Description

Routing switching equipment, method and switching line card board Technical field The present invention relates to the field of communication technology, in particular to a routing and switching device, a method and a switching line card board. Background technique The router is the third layer (L3) of the OSI (Open System Interconnection) protocol model, that is, the packet switching equipment (or network layer relay equipment) in the network layer. The routing technology consists of two most basic activities, namely, determining the most Optimal path and transmission data packets, namely IP packets. After the router receives the message, it first removes the header of the link layer (unpacking), reads the destination address, and then looks up the routing table. If it can determine where to send it next, add the header of the link layer ( Package), forward the message to the next router that can reach the destination. When the next router receives the message, it will also che...
