Description
Technical Field
The invention belongs to the technical field of network communication, and particularly relates to a method and a system for processing an InfiniBand network subnet management message.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The high-speed serial transceiver makes it possible to transmit a great amount of data point to point, and this serial communication technology makes full use of the channel capacity of the transmission medium and reduces the number of required transmission channels and device pins compared with parallel data bus, so as to lower communication cost greatly. A transceiver with excellent performance should have the advantages of low power consumption, small size, easy configuration, high efficiency, etc., so that it can be easily applied to the implementation of technologies related to the network communication field.
InfiniBand (IB) is a computer network communications standard for high performance computing with extremely high throughput and extremely low latency for computer-to-computer data interconnects. InfiniBand also serves as a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems.
The subnetworks in the IB network topology are important components thereof. The master subnet management plays an important role in the subnet. The master subnet management is responsible for searching physical topology in the subnet, distributing Local Identifiers (LID) for nodes, switches and routers in the subnet, maintaining possible paths of each node in the subnet and monitoring and scanning topology change of the subnet in real time.
The Subnet Management Agent (SMA) is attached to each node in the subnet to monitor the internal condition of the node and is communicated with the master subnet manager. And a Subnet Management Interface (SMI) provides a routing function for the communication data packet in the subnet when the nodes in the subnet do not complete the initialization process of distributing LID.
IB networks can be classified into SDR, DDR, QDR, FDR, EDR, etc. according to transmission rates, each of which can be divided into single channel, dual channel, four channel, eight channel, and twelve channel. According to the physical layer coding rule, QDR and the rate below support 8B/10B coding, and FDR and the rate above support 64/66B coding.
Although the advantage of easy configuration of the high-speed serial transceiver is suitable for developing a complex physical layer environment of an IB network, the management design of the upper-layer sub-network can be changed, and the related operations of the upper-layer sub-network management are consistent no matter how the physical layer environment is, but when the IB physical layer and the upper-layer sub-network management are designed based on the high-speed serial transceiver, coupling is easy to occur, so that the design of related modules of sub-network management becomes complicated.

EXAMPLE III
As shown in fig. 1, this embodiment provides an InfiniBand network subnet management message processing system, which adopts the following technical solutions:
an InfiniBand network subnet management message processing system, comprising:
IB physical layer module in use for sending original subnet management data packet to upper layer subnet management layer;
the SMPReceive module is used for monitoring the IB physical layer in real time to obtain an original subnet management data packet, storing the original subnet management data packet according to the format of an interface which is currently butted with the IB physical layer to obtain a complete subnet management data packet, and sending the subnet management data packet without error check to the upper layer subnet management module through a unified subnet management data interface;
the upper-layer sub-network management module is used for monitoring a unified sub-network management data interface in real time, intercepting an upper-layer sub-network management data packet from the check-error-free sub-network management data packet, and correcting a corresponding field in the upper-layer sub-network management data packet to obtain a corrected sub-network management data packet;
and the SMPSend module is used for carrying out arbitration transmission on the modified subnet management data packet.
As shown in fig. 1, it is a complete relationship diagram of the solution described in the embodiment, where due to various physical layer interfaces of the IB network physical layer caused by rate differences, different data interfaces, such as 8B/10B 4x16, 8B/10B 4x32, etc., need to be interfaced between the IB physical layer module and the smprieceve module, and between the Buffer module and the SMPSend module due to different physical layer rates. Because the length of the message related to the IB network link layer subnet management is fixed, in order to prevent the IB network subnet management message processing from being influenced by the condition of the lower physical layer interface, a uniform and unchangeable subnet management data interface is adopted in the link layer message processing. The uniform and unchangeable subnet management data interface is designed according to the format of an IB network subnet management data packet. And removing two byte identifiers of a packet head and a packet tail of the IB network data packet, wherein the width of the subnet management data interface is the complete IB network subnet management data packet, the total 2272 bit width and the byte sequence are big ends. That is, the smprieceive module is a module that stores the original subnet management packets obtained from different physical layers into a complete subnet management packet with the same width as the unified subnet management data interface.
The IB physical layer module is realized according to an IB network physical layer protocol. The data interface width and the channel number of the physical layer are different due to different real-time running speeds, channel numbers and coding rules of the physical layer.
The smprieceve module is a key module for decoupling subnet management related operations from the underlying physical layer environment. The core design idea is to provide a unified and unchangeable subnet management data interface for an upper layer Subnet Management Agent (SMA) module and a Subnet Management Interface (SMI) module, and simultaneously design a corresponding physical layer data interface according to a lower layer physical layer environment. The SMPRIctive module also comprises a CRC check detection unit and a buffer unit so as to store data and convert a clock domain (InfiniBand clock domain is converted into a subnet management processing clock domain) in time.
As shown in fig. 2. The smprieceve module is first at the snooping physical layer module to detect whether there is a subnet management packet. After detecting the subnet management packet, the second step is performed. And receiving and storing the subnet management data packet in a corresponding mode according to the number of interface channels, the data width and the coding mode which are currently in real-time butted with the physical layer module, and simultaneously carrying out clock domain conversion on the data packet. If the current physical layer interface is 4 lanes, 16 bits per lane width, and the encoding scheme is 8B/10B, then 36 clock cycles are required to store the subnet management data in this case. If the current physical layer interface is 4 channels, each channel has 32-bit width, and the encoding mode is not changed, 18 clock cycles are needed for storing subnet management data. Different numbers of channels, data widths and encoding modes of interfaces of different physical layers require different numbers of cycles and different storage formats when the subnet management data packets are stored, and design and development of processing the subnet management data packets by an upper link layer can be influenced if the subnet management data interfaces are not unified. The SMPReceive module stores the data into the uniform subnet management data interface width according to the corresponding channel number, width and coding mode corresponding to different physical layer interface conditions.
Performing CRC on the unified data, and if the CRC does not have errors, providing data to the upper SMA and SMI module; if the error is found, the error is discarded.
As shown in fig. 3, the SMA module monitors the subnet management data interface provided by the smprieceve module in real time, and intercepts a subnet management data packet sent to the SMA module. After intercepting the subnet management data packet of the SMA type, firstly, the operation type to be executed by the data packet is judged. If the method is the Get method, then next step, according to the corresponding field requirement in the subnet management data packet, the corresponding required data is placed at the corresponding field position of the subnet management data packet, then the corresponding content of the related subnet routing field of the subnet management data packet is modified, and finally the subnet management data is provided to the upper Buffer module; if the method is the Set method, modifying corresponding configuration data according to corresponding field requirements in the subnet management data packet, then placing the modified configuration data at the corresponding field position of the subnet management data packet, modifying corresponding content of related subnet routing fields of the subnet management data packet, and providing the subnet management data to an upper Buffer module.
The SMI module also monitors a subnet management data interface provided by the SMPReceive module in real time, and captures a subnet management data packet needing to be forwarded. The SMI module can provide the subnet management data to the upper layer Buffer module only by modifying the corresponding content of the related subnet routing field of the subnet management data packet according to the specification of IB network SMI protocol.
The Buffer block function is substantially identical to the smprieceive block, but the data flow is reversed. As shown in fig. 4, subnet management data of the lower SMI module or SMA module is received and CRC check is performed, and the obtained CRC check code is placed in a corresponding field. And secondly, corresponding to the condition of the unused physical layer interface, the subnet management data is divided again according to the corresponding channel number, width and coding mode. And thirdly, requesting to send to the upper SMPSend module to obtain the response of the upper SMPSend module and then sending data.
The SMPSend module is responsible for carrying out arbitration transmission on data streams from different Buffer modules, and when an SMI and an SMA data stream arrive at the same time, the SMI data stream is preferentially sent.
It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), or the like.
Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
