Router timeout retransmission method and router

Abstract

The invention belongs to the field of communication, and provides a router timeout retransmission method. The method comprises the steps of 101, acquiring the timeout time; and 102, retransmitting a data request to a second path in a shortest path first method when the timeout time exceeds a set threshold. The technical scheme provided by the invention has the advantage of high reliability.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a timeout retransmission method of a router and the router. Background technique [0002] A router is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to channel conditions, and send signals in the order of the best path. The router is the hub of the Internet, the "traffic police". At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The main difference between routing and switching is that switching occurs at layer 2 (the data link layer) of the OSI reference model, while routing occurs at layer 3, the network layer. This difference determines that rout...
