Multi-path routing method and device based on network equipment

Abstract

The invention relates to a multi-path routing method and a device based on network equipment, and the method comprises the steps: S1, establishing a hierarchical structure in a storage node, and enabling the hierarchical structure to sequentially comprise a network equipment set, network equipment and a network port from the top to the bottom; S2, creating a virtual path between the network devices connected with the two network device sets and between the network ports; S3, determining a virtual path according to different path selection strategies, and transmitting data through a logic datalink contained in the virtual path between the network ports; the path selection strategy in the step S3 is specifically as follows: if the network equipment set or the network equipment shares the concurrency performance, the network equipment set or the network equipment adopts a Failover mode, and if the concurrency performance of the network equipment set or the network equipment is independent, the network equipment or the network port adopts a Round robin mode. Compared with the prior art, the method has the advantages of equal load balance, high availability and the like.

Description

technical field [0001] The invention relates to a network data transmission technology, in particular to a multi-path routing method and device based on network equipment. Background technique [0002] In the storage system, data is stored in different physical nodes, which exchange data through high-speed interconnected network devices. Usually, there are multiple network devices in the same physical node, and multiple transmission links established between different network devices in each physical node. When the path fails, the server can transfer the I / O through this transmission link to other normal transmission links, and the application program will not be aware of this change, thereby improving the high availability of the system, and at the same time, the transmission links can be aggregated Use it as a transmission link to achieve I / O load balancing. This method is a multipath method. It can be seen that this method has two advantages: one is to aggregate multipl...

Problems solved by technology

In addition, ports of network devices may share their concurrent capabilities, such as Image 6 Port 1 and port 2 of network device 1 on medium storage node 1, where the capability of a single port is the same as the sum of the capabilities of the two ports, there is no operational meaning in path selection every time switching paths

[0004] It can be seen that the above method will bring the following disadvantages: in the continuous logical path selection, the device at one end of the path may be repeatedly selected, and the logical path will be repeated at the same time, which will cause the load imbalance of the network equipment; The network ports that share the concurrent performance will actually increase the probability of the network device being selected continuously, resulting in instantaneous network congestion. At the same time, it will be meaningless to switch between the network ports that share the concurrent performance, which will increase the running time and will also Bring concurrency performance loss
