Description

A method and system for processing InfiniBand network subnet management messages

technical field

The invention belongs to the technical field of network communication, and in particular relates to a method and system for processing InfiniBand network subnet management messages.

Background technique

The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

High-speed serial transceivers make it possible to transmit a large amount of data point-to-point. This serial communication technology makes full use of the channel capacity of the transmission medium. Compared with the parallel data bus, it reduces the number of required transmission channels and device pins, thus greatly Reduce communication costs. A transceiver with excellent performance should have the advantages of low power consumption, small size, easy configuration, and high efficiency, so that it can be easily used to implement related technologies in the field of network communication.

InfiniBand (abbreviated as IB) is a computer network communication standard for high-performance computing. It has extremely high throughput and low latency, and is used for data interconnection between computers. InfiniBand is also used as a direct or switched interconnect between servers and storage systems, and as an interconnect between storage systems.

The subnet is an important part of the IB network topology. Master subnet management plays an important role in subnetting. The main subnet management is responsible for exploring the physical topology in the subnet, distributing Local Identifiers (LIDs) for nodes, switches, and routers in the subnet, maintaining possible paths for each node in the subnet, and monitoring and scanning subnet topology changes in real time.

The subnet management agent (SMA) attaches to each node in the subnet to monitor the internal conditions of the node and communicate with the main subnet management. The subnet management interface (SMI) provides the routing function for the communication data packets in the subnet when the nodes in the subnet have not completed the initialization process of distributing LID.

The IB network can be divided into SDR, DDR, QDR, FDR, EDR, etc. according to the transmission rate, and each rate can be divided into single-channel, dual-channel, four-channel, eight-channel and twelve-channel. According to the coding rules of the physical layer, the rate of QDR and below supports 8B/10B encoding, and the rate of FDR and above supports 64/66B encoding.

Although the advantages of easy configuration of high-speed serial transceivers are suitable for the development of complex physical layer environments of IB networks, it will also change the design of upper-layer subnet management. Regardless of the physical layer environment, the operations related to upper-layer subnet management are consistent, but When designing IB physical layer and upper-layer subnet management-related operations based on high-speed serial transceivers, it is easy to be coupled, which makes the design of subnet management-related modules cumbersome.

Embodiment Three

As shown in Figure 1, this embodiment provides a system for processing InfiniBand network subnet management messages, which adopts the following technical solutions:

A system for processing InfiniBand network subnet management messages, comprising:

The IB physical layer module is used to send the original subnet management data packet to the upper subnet management layer;

The SMPReceive module is used to monitor the IB physical layer in real time to obtain the original subnet management data packet, and store the original subnet management data packet according to the format of the interface currently connected to the IB physical layer to obtain a complete subnet management data packet, and pass The unified subnet management data interface sends the verified subnet management data packet to the upper layer subnet management module;

The upper-layer subnet management module is used to monitor the unified subnet management data interface in real time, intercept the upper-layer subnet management data packet from the verified subnet management data packet, and correct the corresponding fields in the upper-layer subnet management data packet, Get the corrected subnet management packet;

The SMPSend module is used for arbitrating the modified subnet management data packets.

As shown in Figure 1, it is a complete relationship diagram of the scheme described in the embodiment, wherein due to the various situations of the physical layer interface brought by the IB network physical layer due to the rate difference, between the IB physical layer module and the SMPReceive module, between the Buffer module and the SMPSend Due to the different physical layer rates, the modules need to be connected to different data interfaces, such as 8B/10B 4x16, 8B/10B 4x32 and so on. Since the length of the IB network link layer subnet management related packets is fixed, in order to prevent the IB network subnet management packet processing from being affected by the lower physical layer interface, a uniform and constant Subnet management data interface. The unified and unchanged subnet management data interface is designed according to the IB network subnet management data packet format. Remove the two byte identifiers of the header and tail of the IB network data packet, and the width of the subnet management data interface is the complete IB network subnet management data packet, with a total width of 2272 bits and a big-endian byte order. That is to say, the SMPReceive module stores the original subnet management data packets obtained from different physical layers into a complete subnet management data packet with the same width as the unified subnet management data interface.

The IB physical layer module is implemented according to the IB network physical layer protocol. Due to the different real-time operation rate, number of channels, and coding rules of the physical layer, the data interface width and number of channels of the physical layer will be different.

The SMPReceive module is a key module for decoupling subnet management-related operations from the underlying physical layer environment. Its core design idea is to provide a unified subnet management data interface for the upper subnetwork management agent (SMA) module and subnetwork management interface (SMI) module, and design the corresponding physical layer data interface according to the lower physical layer environment. The SMPRecive module also includes a CRC check detection unit and a buffer unit to store data in time and switch the clock domain (the InfiniBand clock domain is converted to the subnetwork management processing clock domain).

as shown in picture 2. The SMPReceive module first monitors the physical layer module to detect whether there is a subnet management packet. After detecting the subnet management packet, proceed to the second step. According to the number of interface channels, data width, and encoding method that are currently connected to the physical layer module in real time, the subnet management data packet is received and stored in a corresponding manner, and the data packet clock domain conversion is performed at the same time. If the current physical layer interface has 4 channels, each channel has a width of 16 bits, and the encoding method is 8B/10B, then in this case, 36 clock cycles are required to store the subnet management data. However, if the current physical layer interface has 4 channels, each channel has a width of 32 bits, and the encoding method remains the same, it takes 18 clock cycles to store the subnet management data. Different physical layer interface channel numbers, data widths, and encoding methods will require different cycle times and different storage formats for storing subnet management data packets. If the subnet management data interface is not unified, it will affect the processing of the upper link layer. Design and development of network management data package. The SMPReceive module corresponds to different physical layer interfaces, and stores data according to the corresponding channel number, width, and encoding method as a unified subnet management data interface width.

The third step is to perform CRC check on the unified data. If the CRC check is correct, the data is provided to the upper layer SMA and SMI modules; if there is an error, it is discarded.

The SMA module, as shown in FIG. 3 , monitors the subnet management data interface provided by the SMPReceive module in real time, and intercepts the subnet management data packets sent to its own SMA. After intercepting the subnet management data packet of the SMA type, first determine the type of operation to be performed by the data packet. If it is the Get method, then the next step is to place the corresponding required data in the corresponding field position of the subnet management packet according to the requirements of the corresponding fields in the subnet management packet, and then modify the subnet routing field corresponding to the subnet management packet. content, and finally provide the subnet management data to the upper-layer Buffer module; if it is the Set method, the next step is to modify the corresponding configuration data according to the requirements of the corresponding fields in the subnet management packet, and then place the modified configuration data in the subnet The location of the corresponding field in the management data packet, and at the same time modify the corresponding content of the subnet routing field in the subnet management packet, and provide the subnet management data to the upper layer Buffer module.

The SMI module also monitors the subnet management data interface provided by the SMPReceive module in real time, and intercepts the subnet management data packets that need to be forwarded. The SMI module only needs to modify the corresponding content of the subnet routing field in the subnet management data packet according to the IB network SMI protocol, and then provide the subnet management data to the upper layer Buffer module.

The function of the Buffer module is basically the same as that of the SMPReceive module, but the data flow is opposite. As shown in Figure 4, first receive the subnet management data of the lower layer SMI module or SMA module and perform CRC check, and place the obtained CRC check code in the corresponding field. In the second step, corresponding to the unused physical layer interface, the subnet management data is re-divided according to the corresponding channel number, width, and encoding method. The third step is to send a request to the upper-layer SMPSend module, and send the data after receiving the response from the upper-layer SMPSend module.

The SMPSend module is responsible for arbitrating and transmitting the data streams from different Buffer modules. When the SMI and SMA data streams arrive at the same time, the SMI data stream is sent first.
