Information Transmission From The Router

Some routers only support a single protocol, but most routers can support the transmission of multiple protocols, that is, multi-protocol routers. Since each protocol has its own rules, the algorithm of multiple protocols to be completed in one router is bound to reduce the performance of the router. The main job of the router is to find the best transmission path for each data frame passing through the router and efficiently deliver that data to the destination site. It can be seen that the strategy of choosing the best path, that is, the routing algorithm, is the key to the router. In order to complete this work, data related to various transmission paths - routing tables - is stored in the router for route selection. The path table stores the flag information of the subnet, the number of routers on the Internet, and the name of the next router. The path table can be fixed by the system administrator.
