Route learning and forwarding method

Abstract

The invention discloses a route learning and forwarding method. The method comprises the following steps that each router is numbered and an IP address is allocated; the routers learn each other and record learning information to obtain a router information table; each client router learns the client network information of the client to form a routing table of the client network information; eachrouter learns local link information to obtain a global link information table and calculates the shortest path from each router to any router; and the client router receives the network message of the client, and sends the network message to the target client router according to the router information table, the routing table and the shortest path. According to the invention, the intermediate router does not need to store a large amount of routing information, the routing table does not need to be searched again, and the original network message carries complete path information, so that a loop is avoided from the source, and the flow control is easier to grasp.

Description

technical field [0001] The invention relates to the technical field of route data, in particular to a route learning and forwarding method. Background technique [0002] The popularity of the Internet and the wave of cloud computing make us increasingly inseparable from the network environment. With the rapid development of the mobile Internet, various applications and services emerge in an endless stream. Application developers and service providers need to quickly implement their projects or products. In traditional IDC data centers, they generally need to arrange their own or rent server equipment and also It is necessary to build a complex network by yourself, which will definitely take a lot of time and is very error-prone, and it is not easy to expand and achieve disaster recovery. [0003] In the classic network, users actually lack network management capabilities on the cloud. The user has a virtual server of the classic network, and the user only has the ability to...

Problems solved by technology

[0005] At present, the development of routing technology has been very mature and common. The routing learning technology generally uses BGP and other technologies, and the routing forwarding uses routing table technology. However, these two technologies have obvious defects. For routing learning such as BGP, routers only It will care about the status and information of adjacent routers. The learned routing information makes the router only have very limited information and cannot obtain the path and status of the entire network. In fact, many routers in the middle that are only responsible for transmission do not need to learn routing and Save this information; and the routing table technology used in forwarding technology will consume a lot of router performance and increase the corresponding transmission delay because each time the traffic passes through a router, it needs to look up the routing table once
