Method for supporting multiplex extraterritorial service quality based on route information protocol

Abstract

A method for supporting multiple type of extra-domain service quality based on route information protocol includes updating local path information when PVA packet sent from boundary router adjacent to the other domain is received by boundary router, calculating out optimum routes to relevant destination network address prefix, sending these routes to boundary router adjacent to the other domain and to route management module in PVA packet mode, sending these routes to boundary router adjacent to the other domain in PVA packet mode and simultaneously updating path information in local area when intra-domain route redistributed from route management module is received by boundary router.

Description

technical field

[0001] The method for supporting multiple qualities of service based on the RIP protocol belongs to the technical field of the Internet, and in particular relates to router forwarding technology at the network layer. Background technique

[0002] RIP (Routing Information Protocols, Routing Information Protocol) is the most widely used distance vector protocol, which was developed by Xerox in the 1970s. At that time, RIP was part of the XNS (Xerox Network Service, Xerox Network Service) protocol suite. The TCP / IP version of RIP is an improved version of the Xerox protocol. The biggest feature of RIP is that it is very simple regardless of its implementation principle or configuration method. The measurement of RIP is based on the hop count (hops count), and every time a router passes through, the hop count of the path is increased by one. In this way, the more hops, the longer the path, and the RIP algorithm will preferentially select the path with fewer ho...
