Detailed Description

For ease of understanding, a description of some of the concepts related to the embodiments of the present application are given by way of example for reference. The following is shown:

data packet (packet): is a data unit in a transmission control protocol/internet protocol (transmission control protocol/internet protocol, TCP/IP) protocol communication transmission. The data packet includes a physical layer, a link layer, a transmission control protocol (transmission control protocol, TCP) layer, and an internet protocol (internet protocol, IP) layer, which correspond to layer 1, layer 2, layer 3 (layer 3, L3), and layer 4 (layer 4, L4) of the data packet, respectively. Each layer appends a header to the data in the packet, which header contains the necessary information for that layer. The header of the TCP layer of the data packet comprises a source port and a destination port of the data packet, and the header of the IP layer of the data packet comprises a source IP address, a destination IP address and a protocol number of the data packet. In the embodiment of the application, the L3/L4 of the data packet is the TCP/IP layer of the data packet. Resolving the header of the L3/L4 of the data packet can be understood as resolving the header of the TCP/IP layer of the data packet, so as to obtain the source IP address, destination IP address, protocol number, source port and destination port of the data packet, and thus obtain the quintuple information of the data packet.

Quintuple information: the five-tuple information in the embodiment of the application corresponds to the same data flow by all the same data packets.

And (3) packaging: the modem of the terminal needs to receive a plurality of data packets from the air interface side and send the data packets to the application processor for processing, and the data packets are grouped into one data packet to be sent in a grouping way, so that the transmission rate can be improved.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, "/" means or is meant unless otherwise indicated, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone.

The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b or c may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or plural.

Currently, in the case of packet reception, the process of processing a data packet at the terminal side is shown in fig. 1, and the terminal side includes a modem and an application processor. The modem is used for receiving the data packet and sending the data packet to the application processor, and the application processor is used for processing the data packet, and specifically comprises the following steps:

step 1, the modem receives a plurality of data packets from an air interface side.

And 2, the modem packs the plurality of data packets according to the receiving sequence from the air interface side.

Step 2 can be understood as that the modem groups a plurality of data packets into one large data packet (i.e., the grouped data packets) in the order of reception from the air interface side.

And 3, the modem sends the packetized data packet to the application processor through a universal serial bus (universal serial bus, USB).

And 4, the application processor receives the data packets after grouping on the hardware adaptation layer, and transmits the data packets after grouping to the network card layer of the application processor.

Among them, an application processor can be understood as a central processing unit (central processing unit, CPU). The application processor comprises a hardware adaptation layer, a network card layer, a protocol stack layer and an application layer. The header of each layer in the data packet has independent software to parse, wherein the hardware adaptation layer and the network card layer can be understood as software for parsing the header of the data packet link layer, the protocol stack layer in the application processor can be understood as a software collection for parsing the header of the data packet TCP layer and the header of the IP layer, and the application layer comprises one or more application programs. The application processor may run different software on different layers to perform different actions. For example, the application processor is mainly responsible for transmitting the received data packets after grouping to the network card layer on the hardware adaptation layer.

Specifically, in step 4, the application processor dispatches the packetized data packet to a core (i.e., a single core) of the application processor on the hardware adaptation layer, and the packetized data packet is transmitted to the network card layer of the application processor through the single core.

And 5, unpacking the packed data packets on the network card layer by the application processor to obtain a plurality of data packets.

After receiving the data packets after grouping, the application processor can unpack the data packets after grouping into a package format on the network card layer to obtain a plurality of data packets. It is also understood that one large packet (i.e., a packetized packet) is unpacked into a plurality of packets.

Specifically, in step 5, the application processor unpacks the data packets after the unpacking through the single check on the network card layer to obtain a plurality of data packets.

And 6, the application processor transmits the data packets to a protocol stack layer of the application processor on the network card layer.

Specifically, in step 6, the application processor dispatches the multiple data packets obtained after unpacking to a single core on the network card layer to transmit to the protocol stack layer.

Therefore, when the downlink rate of the air interface side is too high, and the modem receives more data packets from the air interface side, the application processor unpacks the packets and transmits a plurality of data packets on the network card layer through a single core, which can cause a larger load born by the single core, and further cause a decrease in the speed of processing the data packets by the application processor, namely a decrease in the processing capacity of the terminal side.

And 7, the application processor decodes the data packets on the protocol stack layer to obtain a plurality of user data in the data packets, and copies the user data to a core corresponding to the application program.

After receiving a plurality of data packets on a protocol stack layer, an application processor can parse the data packets to obtain a plurality of user data in the data packets, which can be understood as analyzing each data packet in the data packets layer by layer to obtain the user data in each data packet.

Specifically, in step 7, the application processor decodes the data packets through the single check multiple data packets on the protocol stack layer to obtain multiple user data in the multiple data packets, and schedules the multiple user data to the single core and copies the multiple user data to the core corresponding to the application program.

Therefore, when the number of user data obtained by the packet disassembly is large, the application processor decodes the packet by checking a plurality of packets through a single core on the protocol stack layer and copies the user data in the packet to the core corresponding to the application program, which results in a large load borne by the single core and further results in a decrease in the processing capacity of the terminal side.

It can be seen that, in the process of processing the data packet at the terminal side, the processes of unpacking, unpacking the data packet and copying the user data to the core corresponding to the application program by the application processor in steps 5 to 7 are processes with larger load occupation in the process of processing the data packet by the application processor. However, in the above-mentioned packet-collecting scenario, the terminal side only processes the data packet through a single core, so that the situation that the load of one core of the application processor is too high and the load of the other cores is low or in an idle state occurs, and the processing time and the processing speed of processing the data packet through a single core are long, so that the processing capability of the terminal side is reduced.

Therefore, in order to process the data packets through the multiple cores and balance the loads borne by the multiple cores, a scheme is proposed in which the application processor unpacks the packets on the network card layer and then parses the headers of the L3/L4 of the multiple data packets, that is, the headers of the TCP/IP layers of the multiple data packets. As shown in fig. 2, this scheme can be understood as replacing the above-mentioned steps 5 to 7 with steps 5 '-7', the remaining steps 1 to 4 are unchanged, and the steps 5 '-7' are as follows:

and 5', unpacking the packed data packets on the network card layer by using the processor to obtain a plurality of data packets, and analyzing the heads of L3/L4 of the plurality of data packets.

The five-tuple information of the data packet can be obtained by analyzing the head of the L3/L4 of the data packet, and the data stream to which the data packet belongs can be determined according to the five-tuple information of the data packet. The same data stream is initiated by the same application program, and the same application program can initiate a plurality of different data streams, or it can be understood that the same data stream corresponds to the same application program, and a plurality of different data streams can correspond to the same application program. The application processor can analyze the heads of the L3/L4 of the data packets on the network card layer to distinguish the data packets according to the data flow, namely, the data packets are split.

Specifically, in step 5', the application processor unpacks the data packets after unpacking through a single core on the network card layer to obtain a plurality of data packets, and then analyzes the heads of the L3/L4 of the plurality of data packets through the single core.

And 6', the application processor transmits a plurality of data packets to a protocol stack layer of the application processor on the network card layer.

The protocol stack layer that transmits the plurality of data packets to the application processor can be understood as: according to the result of the splitting of the plurality of data packets in the step 5 ', the data packets belonging to the same data stream are scheduled to the same core and transmitted to the protocol stack layer of the application processor, namely, the application processor in the step 6' schedules the plurality of data packets obtained after the splitting of the packets on the network card layer to the plurality of cores and transmits to the protocol stack layer.

And 7', the application processor unpacks the data packets on the protocol stack layer to obtain a plurality of user data in the data packets, and copies the user data to a core corresponding to the application program.

Specifically, in step 7', the application processor decodes the data packet by checking the plurality of data packets on the protocol stack layer to obtain a plurality of user data in the plurality of data packets, and schedules the plurality of user data to the plurality of cores to copy to the cores corresponding to the application program. It is also understood that a plurality of user data obtained by parsing a plurality of packets belonging to the same data stream are scheduled to the same core and copied to the core corresponding to the application corresponding to the data stream.

After the steps 5-7 are replaced by the steps 5 '-7', the application processor can process the data packet through a plurality of cores, so that the load born by a single core is reduced. However, the application processor adds an additional processing procedure on the network card layer, that is, the application processor adds a processing procedure of analyzing the header of the L3/L4 of the plurality of data packets on the network card layer, and the application processor still can analyze the data packets according to the original processing flow on the protocol stack layer. This approach therefore causes additional consumption by the application processor, introducing additional processing overhead.

Accordingly, the present application proposes a method of processing data packets, which may be applied to an electronic device. In view of the problem that in the prior art, under a packet-collecting scene, a single core processes a data packet, which results in the reduction of the capability of an application processor to process the data packet, the application divides a plurality of received data packets into at least one data segment, each data segment corresponds to an application program, each data segment comprises a data segment header, and one or more received data packets in each data segment are transmitted to a core corresponding to the application program according to the data segment header, thereby reasonably balancing the load born by a plurality of cores of the application processor, avoiding the situation that one core bears higher load and other cores bear lower load or are in an idle state, and improving the capability of the electronic equipment to process the data packet.

As shown in fig. 3, the method for processing a data packet according to the embodiment of the present application may be applied to a scenario of packet reception, where the scenario includes an electronic device and an external device, and the electronic device may be, for example, a chip, a mobile terminal, a tablet computer, a notebook computer, a personal computer (personal computer, PC), etc., and the external device may be, for example, a server, etc. The electronic device and the external device can communicate with each other, for example, data packets can be mutually transmitted, the external device is used for sending a plurality of receiving data packets to the electronic device, and the electronic device is used for receiving and processing the plurality of receiving data packets sent by the external device. Communication between the electronic device and the external device may pass through one or more intermediate nodes, such as a base station, a wireless router, a wired router, a gateway or relay node, etc.

The different processing units may be separate components or may be integrated in one or more processors. For example, the processor 401 may include a graphics processor (graphics processing unit, GPU), a central processor (central processing unit, CPU), and/or a neural network processor (neural network processing unit, NPU), etc. In the present embodiment, the processor 401 includes a modem 4011 and an application processor 4012.

It is understood that a data segment corresponds to a data stream, i.e. one or more received data packets in a data segment correspond to an application to which the same data stream corresponds, whereas a data stream is initiated by an application, and thus a data stream may also be understood to correspond to an application. The modem 4011 is further configured to send out the packetized data packets.

The application processor 4012 may be operable to receive and process received data packets. In this embodiment of the present application, the application processor 4012 may be configured to unpack the packed data packet to obtain at least one data segment, and transmit one or more received data packets in each data segment to a core corresponding to the application program.

The chip interface 403 is used to communicate with external devices of the chip, for example, with a server.

In the method for processing data packets provided by the present application, the electronic device is taken as an example of a chip, and in the process of packaging and receiving packets by the chip, a plurality of received data packets are divided into at least one data segment, each data segment corresponds to an application program, each data segment comprises a data segment header, and a process of transmitting one or more received data packets in each data segment to a core corresponding to the application program according to the data segment header is described.

As shown in fig. 5, an embodiment of the present application provides a method for processing a data packet, where the method is applied to an electronic device, and the electronic device includes a plurality of cores, and takes the electronic device as a chip 400 for example, the method includes:

step 501, demodulating a plurality of received data packets, and dividing the plurality of received data packets into at least one data segment.

The plurality of received data packets may be understood as a plurality of data packets received by the electronic device from an external device, for example, a plurality of data packets received from a server, and the plurality of received data packets may be from different servers, and the plurality of received data packets may be, for example, a plurality of ethernet data packets. Each of the plurality of received data packets has a corresponding data stream, and the corresponding data stream of each of the plurality of received data packets may be the same or different. The data flow is initiated by an application program, one application program can initiate a plurality of data flows, and it can be understood that the same application program can initiate a plurality of different data flows, namely a plurality of data flows with different quintuple information. One data stream corresponds to one application, and it is understood that each received data packet has a corresponding application.

Dividing the plurality of received data packets into at least one data segment according to the data stream, specifically dividing one or more received data packets corresponding to the same data stream in the plurality of received data packets into the same data segment, can be understood as that one data stream corresponds to one data segment. Each data segment in the at least one data segment corresponds to an application program, it may be understood that one data segment corresponds to an application program, and a plurality of data segments may correspond to the same application program, that is, a plurality of data streams corresponding to the plurality of data segments are initiated by the same application program.

Each of the at least one data segment includes a data segment header for identifying an application, e.g., the data segment header includes data stream Identification (ID) information for indicating the application to which the data segment corresponds, which may be understood as indicating the application to which one or more received data packets divided into the data segment correspond.

In an exemplary embodiment, after receiving a plurality of received data packets, the electronic device demodulates the plurality of received data packets, identifies data streams corresponding to the plurality of received data packets, i.e., divides the plurality of received data packets into a plurality of data segments, and divides one or more received data packets belonging to a same data stream into a plurality of data segments. As shown in fig. 6, taking a plurality of received data packets as a received data packet 0, a received data packet 1 and a received data packet 2 as an example, after demodulating the received data packet 0, the received data packet 1 and the received data packet 2, the electronic device identifies a first data stream corresponding to the received data packet 2, and a second data stream corresponding to the received data packet 0 and the received data packet 1. The electronic device individually packages the received data packet 2 in a first data segment, and the first data segment includes a data segment header 0 for identifying a first application program corresponding to the first data segment. The electronic device packs the received data packet 0 and the received data packet 1 together in the second data segment according to the received sequence, and the second data segment includes a data segment header 1 for identifying a second application program corresponding to the second data segment. The first application program and the second application program may be the same application program or different application programs.

Specifically, the step 501 may be performed by a modem in the electronic device, for example, may be performed by the modem 4011 in fig. 4.

In some alternative embodiments, step 501 specifically includes:

and 5011, determining a data segment corresponding to each received data packet according to five-tuple information of each received data packet in the plurality of received data packets, so as to pack one or more received data packet groups in each data segment.

In step 501, the demodulation of the plurality of received data packets may be, for example, parsing the header of the L3/L4 of the plurality of received data packets to obtain quintuple information of each received data packet. The data packets with the identical quintuple information correspond to the same data stream, i.e. the data packets with the identical quintuple information can be divided into the same data segment and correspond to the same application program. It can be understood that the process of parsing the header of the L3/L4 of the plurality of data packets on the network card layer by the application processor in the prior art step 5' is performed by the modem 4011 of the present application, and the modem 4011 of the present application has the capability of parsing the header of the L3/L4 of the plurality of received data packets to obtain five-tuple information of each received data packet. Illustratively, the modem 4011 of the application includes a hardware accelerator, and the modem 4011 performs the step of parsing the header of the L3/L4 of the plurality of received data packets to obtain five-tuple information of each received data packet through the hardware accelerator. After obtaining the quintuple information of each received data packet, the modem 4011 can package one or more received data packets with the same quintuple information in the same data segment, which can also be performed by a hardware accelerator in the modem 4011.

The electronic device determines a data segment corresponding to each received data packet according to the five-tuple information of each received data packet after obtaining the five-tuple information of each received data packet, and packages one or more received data packets with the same five-tuple information in the same data segment.

As shown in fig. 6, the electronic device packages one or more received data packet groups with the same quintuple information in the same data segment in the order in which the plurality of received data packets are received. The plurality of received data packets after grouping include a grouping header, a data segment header of each data segment, and one or more received data packets in each data segment. The packet header is used for storing description information of a plurality of received data packets after the whole packet is formed, the data segment header of each data segment is used for identifying a data stream corresponding to the data segment, namely, an application program corresponding to the data segment, and one or more received data packets in each data segment are one or more received data packets corresponding to the same data stream, namely, one or more received data packets corresponding to the application program identified by the data segment header.

Taking a universal serial bus (universal serial bus, USB) network control model (network control model, NCM) packet format as an example, the plurality of received packets after being packetized are as shown in fig. 7, and include an NCM header, a plurality of NCM packet pointers (NDPs), and a plurality of received packets.

The NCM header may be understood as a packet header, and is used to store description information of a plurality of received data packets after being packetized. The NCM header includes information such as an NCM transport header (NCM transfer header, NTH), a length (NCM header), and a pointer (NDP). The NTH is a packet identifier, used for storing a fixed string application specific integrated circuit (application specific integrated circuit, ASIC) code, and the length (NCM header) is used for describing the length of the entire NCM header, and the pointer (NDP) is used for pointing to the position of the first NDP in the plurality of received data packets after the packet is assembled, which can be understood as being capable of indexing to the first NDP header after parsing into the pointer (NDP).

The plurality of NDPs may be understood as a plurality of data segments, and currently, in the NCM packet format specified by the USB communication device class (communication device class, CDC), the partitioning rule of each NDP is not specified.

As shown in fig. 7, the plurality of NDPs includes NDP0 and NDP1, and NDP0 includes a received data packet 2, and NDP1 includes a received data packet 0 and a received data packet 1. NDP0 includes information such as NDP0 header, length (NDP 0), pointer (next NDP), pointer (received packet 2), and length (received packet 2). The NDP0 header may be understood as a data segment header. Currently, in the NCM packet format of the USB CDC specification, the NDP header defaults to store the "ncmx" string ASIC code value, and in this embodiment, the NDP header is optimized to store information for identifying the application program. It should be understood that, when the NDP0 header is used to indicate information of an application program corresponding to the NDP0, for example, store the data stream ID information, and exemplarily put the data stream ID information into the NDP0 header, a fixed character may be placed in the first 16 bits (bits), and the data stream ID information is placed in the last 16 bits, which is not limited in this application. Length (NDP 0) is used to describe the length of the entire NDP0, a pointer (next NDP) is used to point to the location of the next NDP, a pointer (received packet 2) is used to point to the location of the received packet 2, and length (received packet 2) is used to describe the length of the received packet 2.

The format of NDP1 is similar to that of NDP0, and NDP1 includes information such as NDP1 header, length (NDP 1), pointer (next NDP), pointer (received packet 0), length (received packet 0), pointer (received packet 1), and length (received packet 1). The data stream ID information stored in the NDP1 header is different from the data stream ID information stored in the NDP0 header, which may be understood that NDP1 and NDP0 correspond to different applications, the length (NDP 1) is used to describe the length of the entire NDP1, the pointer (next NDP) is used to point to the position of the next NDP, when NDP1 is the last NDP, it may be understood that when the current data segment is the last data segment, the pointer (next NDP) =null, the pointer (received data packet 0) is used to point to the position of the received data packet 0, the length (received data packet 0) is used to describe the length of the received data packet 0, the pointer (received data, 1) is used to point to the position of the received data packet 1, and the length (received data packet 1) is used to describe the length of the received data packet 1.

The plurality of received data packets may be, for example, a plurality of ethernet data packets, and according to the quintuple information of each received data packet, one or more received data packets with the same quintuple information are grouped into the same data segment according to the grouping format of fig. 6 or fig. 7.

In the NCM group packet format of the CDC protocol specification illustrated in fig. 7, the NDP includes one or more received data packets, which may be understood as including pointer information of the one or more received data packets, where the one or more received data packets are indexed by the pointer information of the one or more received data packets. For example, the received data packet 1 is indexed to the position of the received data packet 1 by pointer (received data packet 1) information in the NDP1, and the NDP1 does not directly include the received data packet 1, but includes pointer (received data packet 1) information indicating the position of the received data packet 1, that is, it may be indicated that the NDP1 includes the received data packet 1. Accordingly, the packet format proposed in the embodiment of the present application may also be a manually defined packet format, where each data segment directly includes one or more received data packets, where the one or more data packets correspond to the same data stream, i.e. to the same application.

Step 502, at least one data segment is parsed to obtain a data segment header, and one or more received data packets in each data segment are transmitted to a core corresponding to an application program according to the data segment header.

The parsing of the at least one data segment may be understood as that the electronic device unpacks the multiple received data packets after the unpacking to obtain a data segment header included in each data segment of the at least one data segment and one or more received data packets in each data segment.

An electronic device comprises a plurality of cores, it being understood that an application processor in the electronic device comprises a plurality of cores, and an application program corresponds to one core, it being understood that an application program runs on one core. And according to the data segment header of each data segment obtained by analyzing at least one data segment, wherein the data stream ID information included in the data segment header can identify the application program corresponding to the data segment. Transmitting one or more received data packets in each data segment to the core corresponding to the application corresponding to the data segment may be understood as scheduling the one or more received data packets to run on the core corresponding to the application corresponding to the data segment.

The electronic device may, for example, unpack the packed multiple received data packets to obtain a data segment header of each data segment and one or more received data packets in each data segment, and transmit, according to an application program identified by the data segment header of each data segment, one or more received data packets in each data segment to a core corresponding to the corresponding application program, and run the application program on the core to process the one or more received data packets. Referring to the grouped multiple received data packets shown in fig. 6, the electronic device unpacks the grouped multiple received data packets to obtain information such as a data segment header 0, a received data packet 2, a data segment header 1, a received data packet 0, and a received data packet 1. The electronic device transmits the received data packet 2 to the core corresponding to the first application program identified by the data segment header 0 according to the data segment header 0, and operates the first application program on the core corresponding to the first application program so as to process the received data packet 2. The electronic device transmits the received data packet 0 and the received data packet 1 to a core corresponding to the second application program identified by the data segment header 1 according to the data segment header 1, and runs the second application program on the core corresponding to the second application program so as to process the received data packet 0 and the received data packet 1.

Specifically, the step 502 may be performed by an application processor in the electronic device, for example, may be performed by the application processor 4012 in fig. 4.

In some alternative embodiments, the application processor includes a hardware adaptation layer, a network card layer, a protocol stack layer, and an application layer. The header of each layer in the data packet is provided with independent software for analysis, wherein the hardware adaptation layer and the network card layer can be understood as software for analyzing the header of the data packet link layer, the protocol stack layer in the application processor can be understood as a software collection for analyzing the header of the data packet TCP layer and the header of the IP layer, the application layer comprises one or more application programs, one application program runs on one core, and the hardware adaptation layer, the network card layer and the protocol stack layer support multi-core operation. Step 502 specifically includes:

and 5021, analyzing at least one data segment on the network card layer to obtain a data segment header, and determining an application program according to the data segment header.

After receiving the multiple received data packets after the grouping, the electronic device transmits the multiple received data packets after the grouping to the network card layer on the hardware adaptation layer. The electronic equipment unpacks the plurality of packed received data packets on the network card layer to obtain the data segment header of each data segment, and determines the application program corresponding to each data segment according to the application program identified by the data segment header.

Step 5022, transmitting one or more received data packets from the network card layer to the protocol stack layer.

The electronic device transmits one or more received data packets corresponding to the same application program to the protocol stack layer, which can be understood that the electronic device schedules one or more received data packets corresponding to the same application program to the same core for transmission to the protocol stack layer, that is, the electronic device schedules one or more received data packets corresponding to different application programs in a plurality of received data packets to different cores for transmission to the protocol stack layer.

The electronic device transmits one or more received data packets in each data segment to the protocol stack layer through different upload queues, illustratively, on the network card layer according to the application program of the data segment header identification of each data segment. Wherein one or more received data packets in the same data segment are transmitted in the same upload queue.

And 5023, analyzing one or more received data packets on the protocol stack layer to obtain analyzed data.

The electronic equipment analyzes the received data packets layer by layer on a protocol stack layer to obtain analyzed data, and one or more pieces of data in the same data segment correspond to the same application program.

Step 5024, the parsed data is transmitted to the core corresponding to the application program.

The electronic device transmits the parsed data to a core corresponding to an application corresponding to the parsed data, that is, the parsed data is transmitted to a core corresponding to an application corresponding to a data segment corresponding to the parsed data. It may be understood that one or more received data packets corresponding to the same data segment in the plurality of received data packets correspond to the same application program, one application program corresponds to one core, and data obtained by parsing the one or more received data packets corresponding to the same data segment is scheduled to the core corresponding to the corresponding application program.
