Message processing method and device

Abstract

The invention discloses a message processing method and device. The method comprises receiving first sub message, which comprises a serial number and a destination address, sent by first PCIE bus equipment, determining whether the serial number of the first sub message is equal to a target serial number which is a serial number of next sub message adjacenet to a serial nunber of sub messafe sent to second PCIE bus equipment before the first sub messafge is received, storing the first sub message if the serial number of the first sub message is equal to the target serial number, receiving second sub message sent by the first PCIE bus equipment, sending the second sub message to the second PCIE bus equipment through a PCIE bus when the serial number of the second sub message is equal to the target serial number, where in the destination address of the first sub message is the same as a destination address of the second sub message, updating the target serial number, and sending the stored first sub message to the second PCIE bus equipment through the PCIE bus when the serial number of the first sub message is equal to the updated target serail number. According to embodiments of the invention, sequantial transmission of message in a PCIE system can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a message processing method and device. Background technique [0002] With the continuous development of the Peripheral Component Interface Express (PCIE) bus, the PCIE bus has developed from intra-system interconnection to inter-system interconnection. Because in the PCIE system structure, the PCIE bus can only realize short-distance transmission of messages, so that when When the two systems are far apart, the transmission of messages between the two systems cannot be completed through the PCIE bus. Therefore, the Ethernet link layer is used to realize the long-distance transmission of messages. Due to the limited capacity of the link layer, when the capacity of the transmitted message is greater than the maximum capacity of the link layer, it is necessary to divide the message into sub-capacities with smaller capacity. Packet to ensure that the capacity of each sub-packe...

AI Technical Summary

Problems solved by technology

When the bandwidth of the PCIE bus is greater than the bandwidth of the link layer, these sub-messages will be transmitted through multiple link-layer channels. Since the delays of different link-layer channels are different, the order of the sub-messages received by the receiving end is different from that of the link layer. The order of sub-messages sent by the sender is different, which will conflict with the requirements for sequential transmission of messages in the PCIE system
