Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
With the deepening of the trend of IP, more and more services are encapsulated into ethernet packets for transmission, but the overhead of the ethernet packet header is at least 38 bytes, and when only the services are concerned, the overhead proportion is large, so the invention mainly proposes to compress the ethernet packet header to improve the utilization rate of the air interface bandwidth and save the limited air interface bandwidth resources. For the problem of compression of ethernet data, there is no relevant solution in the current microwave communication.
Fig. 1 is a flowchart of a method for compressing an ethernet packet according to an embodiment of the present invention, and as shown in fig. 1, the method of the embodiment includes the following steps:
s11, receiving an Ethernet message;
s12, compressing the layer 2 message header and/or the layer 3 message header of the Ethernet message.
Fig. 2 is a flowchart of a method for decompressing an ethernet packet according to an embodiment of the present invention, and as shown in fig. 2, the method of the embodiment includes the following steps:
s21, receiving an Ethernet message;
s22, decompressing the layer 2 message header and/or layer 3 message header of the Ethernet message.
The method for processing the Ethernet message provided by the embodiment of the invention comprises the following steps: the compression of the layer 2 message header and/or the compression of the layer 3 message header can identify a Vlan (virtual local area network) mark, realize the compression and self-adaptive decompression processing of the message, have error correction capability and ensure the normal operation of the system. The invention reduces the data volume in transmission by compressing the Ethernet message header in service, thereby achieving the purpose of saving air interface bandwidth.
For the compression of layer 2 headers, as shown in fig. 3, the following steps are included:
step 2001: receiving an IP message (namely an Ethernet message), and comparing the data of the layer 2 message header with the data in the layer 2 compression table;
specifically, after receiving an IP packet, the header compression of the layer 2 packet is started, and the MAC (media access control) header data of the packet is compared with the layer 2 compression table, and if the header data is the same as the MAC header data, the step 2002 is performed, and if the header data is not the same as the MAC header data, the step 2003 is performed.
Step 2002: replacing the data of the layer 2 message header with the corresponding compression identifier in the layer 2 compression table;
when the coming MAC message header is consistent with the data in the layer 2 compression table, the layer 2 enters a compression state, and at the moment, the whole MAC part of the layer 2 is replaced by a corresponding layer 2 compression identifier in the layer 2 compression table to be transmitted in a link.
Step 2003: generating a compression identifier, transmitting the Ethernet message carrying the compression identifier, and updating a layer 2 compression table;
thus, when an ethernet packet with the same layer 2 header data is received next time, the generated compression identifier can be used to replace the layer 2 header data.
When the coming MAC message head is not consistent with the data in the layer 2 compression table, the layer 2 message head enters an updating state, an updating mark is generated at the moment, the updating mark can be added to the front of the MAC of the layer 2 data, then the updating mark is transmitted to the opposite end, and the compression table is updated.
The decompression process of the layer 2 header, as shown in fig. 4, includes the following steps:
step 2010: the network element equipment at the decompression end firstly detects and identifies whether a layer 2 compression identifier exists in the Ethernet message, if not, the Ethernet message is an uncompressed message, and then the step 2020 is executed; if yes, further identifying whether the message is a compression status message or an update status message, if yes, turning to step 2030; if yes, go to step 2040.
In this embodiment, if the network element device determines that the data of the layer 2 packet header only includes the compression identifier, or only includes the compression identifier and the check information, the network element device identifies the packet as a compression status packet.
Step 2020: and carrying out transparent transmission processing on the uncompressed message.
Step 2030: for the message in the compression state, firstly, the compression identification is identified, and the corresponding layer 2MAC data is taken out from the decompression table according to the compression identification, so as to restore the original message.
Step 2040: for the update message, the decompression end first takes out the compression identifier, restores the original MAC data from the message, and then proceeds to step 2050.
Step 2050: and entering a synchronous updating state of a decompression table, and storing the corresponding relation between the compression identifier and the restored original layer 2MAC data into the decompression table to ensure that the compression table is consistent with the decompression table.
For the layer 3 compression flow, as shown in fig. 5, the following steps are included:
step 3001: grouping: after receiving a new Ethernet message, if the Ethernet is identified as a layer 3 message, grouping the data of the layer 3 message header of the message, wherein the subsequent compression process is the compression process for each group.
Step 3002: sectioning: each group of data is subdivided into N sections, and each section is a minimum unit for message compression;
for example, 16 bits as a section.
Step 3003: compression: comparing each group of message data with a local layer 3 compression table, and respectively processing the following steps according to the comparison result:
if the data of each measure in the group is consistent with the data in the layer 3 compression table, replacing the data of the group with the compression identifier corresponding to the group;
if the data in the group for which there is a partial section does not match the data in the layer 3 compression table, replacing the data of the group with the corresponding compression flag of the group, the data indicating a partially different section number and section, and updating the layer 3 compression table, and then proceeding to step 3004;
if the data of each section in the group is not consistent with the data in the layer 3 compression table, a compression flag is assigned to the group, the data of the group is replaced by the compression flag, the number of each section and the data of each section, and the layer 3 compression table is updated, so that when an ethernet packet is received in which the data of the corresponding group in the header of the layer 3 packet is the same, the data of the group is replaced by the assigned compression flag, and then the process goes to step 3004.
Step 3004: framing, framing each compressed packet, for example, the compressed packet is marked before, and adding different sections in each packet after the packet, and transmitting the packet.
For the compression of the layer 3 message, the packet may not be used, and the compression may be performed directly in small sections, for example, the following steps are included:
3011, dividing the data of layer 3 header of the ethernet packet into a plurality of sections;
step 3012, compare the data of each section with the data in the layer 3 compression table, and according to the comparison result, perform the following processing:
if the data of each measure is consistent with the data in the layer 3 compression table, replacing the data of the layer 3 message header with the corresponding compression identifier; if the data of partial sections are inconsistent with the data in the layer 3 compression table, replacing the data of the layer 3 message header by the corresponding compression identification, section number indicating partial difference and section data, and updating the layer 3 compression table; if the data of each subsection is not consistent with the data in the layer 3 compression table, a compression identifier is allocated to each subsection, the compression identifier, all different subsection numbers and the data of each subsection are used for replacing the data of the layer 3 message header, and the layer 3 compression table is updated, so that when an Ethernet message with the same data of the layer 3 message header is received, the data of the layer 3 message header can be replaced by the allocated compression identifier.
The decompression process for layer 3 messages (not grouped), as shown in fig. 6, includes the following steps:
step 3010: the network element equipment at the decompression end analyzes that the layer 3 message is a common message, a compressed message or an updated message, the common message is subjected to transparent transmission processing, the step 3020 is carried out on the compressed message, and the step 3030 is carried out on the updated message;
in this embodiment, if the network element device determines that the data of the layer 3 packet header only includes a compression identifier, or only includes a compression identifier and check information, or includes a compression identifier, and indicates data of a section number and a section that are different in part, the network element device identifies the data as a compressed packet; and if the data of the layer 3 message header comprises a compression identifier and data indicating all different section numbers and sections, identifying the message as an updating message.
Step 3020: the decompression processing of the compressed message is as follows:
if the network element equipment judges that the data of the layer 3 message header only comprises a compression identifier, taking corresponding data from a layer 3 decompression table according to the compression identifier, and restoring the data of the layer 3 message header;
if the data of the layer 3 message header only comprises the compression identification and the check information, taking corresponding data from a layer 3 decompression table according to the compression identification, and restoring the data of the layer 3 message header; then, checking the restored data according to the checking information, and if the checking result is wrong, returning a feedback message carrying the compression identifier to the sending end of the Ethernet message;
if the data of the layer 3 message header comprises the compression identification, the bar number indicating different parts and the bar data, taking the corresponding data from the layer 3 decompression table according to the compression identification, and replacing the data corresponding to the bar number in the taken data with the bar data.
Step 3030: and storing the corresponding relation of the compression identification, the indication of all different section numbers and the section data in the data of the layer 3 message header into a layer 3 decompression table so as to update the recovered message into a local decompression table and keep the message consistent with the compression table.
