Embodiment Construction

[0076] The cores of the forwarding engine state detection method and the routing device of the present invention are: the forwarding engine determines the states of other forwarding engines according to the predefined frames it receives and broadcasts from other forwarding engines.

[0077] The method and routing device provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0078] The forwarding engine in the present invention needs to detect the states of other forwarding engines according to the predefined frames broadcast and sent by other forwarding engines. The predefined frames can be newly constructed frames according to the detection needs, or can be broadcast and sent by existing forwarding engines. frame.

[0079] In the description of the following embodiments, the method for detecting the state of the forwarding engine and the routing device of the present invention will be described in detail by takin...

Abstract

The invention relates to a method for detecting the condition of transfer engine and relative route device. It is characterized in that: the transfer engine, based received predefined frame of other transfer engines, fixes the conditions of other engines. The invention can make the transfer engine directly and quickly detect the conditions of other transfer engines, without increasing hardware wires and the hardware complexity; to avoid the process that the route process / manage system informs other transfer engines about the abnormal condition of one transfer engine, to reduce the detecting time. The invention can be used in quick re-route technique, to effectively reduce the service interrupt time caused by the failure of transfer engine, to reduce the detecting cost and improve the transmission reliability.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a forwarding engine state detection method and routing equipment. Background technique [0002] A router is a dedicated device for network interconnection. It is widely used in the fields of Internet / Intranet, LAN interconnection, remote LAN access, small home office, etc., as well as private networks and commercial networks of banking, transportation, post and telecommunications departments. [0003] Routers work at the third layer of the OSI (Open System Interconnect) reference model, the network layer. The basic function of a router is to find a path for the IP message passing through it, that is, route, and then forward the IP message to the next station or the destination host. When a router connects two different types of networks, it must complete the conversion of various protocols while forwarding packets, and unify the upper layer of packets into TCP / IP ...
