Problems solved by technology

However, according to the fast start feature of the RoCEv2 protocol, the packet traffic sent from a certain source port may be relatively large in a certain period of time. In addition, the randomness of the hash may also cause a certain path in a multipath network to The traffic at a certain moment is large, which may lead to the congestion of a certain path in the multi-path network
When the network is congested, it will not only increase the network delay, but also increase the possibility of network packet loss, resulting in a decrease in the effective bandwidth of network transmission.

Abstract

The present invention proposes a message transmission method and an apparatus for implementing the same. In the prior art, the routing device selects a forwarding path according to the hash value of the quintuple information of the forwarded message. The traffic of the packets on each path may be unbalanced because the quintuple information of the packets sent by the different queues may be the same or be corresponded to the same forwarding path. In the method of the present invention, the packet to be sent is divided into a plurality of packets, and the packets in different packets have different source port information, and the header carried in each packet carries the write address of the massage in the memory in the destination server. In this way, the packets to be sent are forwardedon different paths, which increases the balance of network traffic.

Description

technical field [0001] The present invention relates to the technical field of message transmission, in particular to a method and device for message transmission. Background technique [0002] In a data communication system, in order to increase the speed of message transmission between servers, a Remote Direct Memory Access (English: Remote Direct Memory Access, RDMA for short) technology is usually used for connection. RDMA is to transfer data directly to the storage area of ​​the computer through the network, and quickly move the data from one system to the remote system memory without affecting the operating system. RDMA eliminates the overhead of external memory copying and context switching, thus freeing up memory bandwidth and CPU cycles for improved application performance. [0003] Converged Ethernet-based remote direct memory access (English full name: RDMA over ConvergedEthernet, abbreviation: RoCE) is a type of RDMA technology that allows servers to perform rem...
