Abstract

The invention discloses a routing determination method and a routing device. The method comprises the following steps: based on a preset link detection mode, the routing device determines that a broadcast link where the device is has oscillation; when a present assigned intermediate system at the broadcast link is a self distant end neighbor device, a local assigned intermediate system is selected from the device and a self local neighbor device; based on the selected local assigned intermediate system, a self latest LSP (link-state packet) is determined; according to the self latest LSP, and a received latest LSP of the neighbor device of the device, routing calculation is carried out, and a latest routing is determined. When the broadcast link has oscillation, one end of the broadcast link has a plurality of routing devices, and the assigned intermediate system is not included, by employing a scheme provided by an embodiment of the invention, the routing calculation is carried out, and routing convergence can be realized.

Description

technical field

[0001] The present invention relates to the technical field of routing in the technical field of network communication, in particular to a routing determination method and routing equipment. Background technique

[0002] With the development of network technology, more and more users use high-speed dedicated broadcast link (generally 10Mbps or more bandwidth) to replace low-speed DDN (DIGITAL DATA NETWORK, digital data network) dedicated line (general bandwidth around 2Mbps) for data transmission. For example, a typical example is that a bank uses an MSTP (Multi-Service Transport Platform, Multi-Service Transport Platform) line to replace the original low-speed DDN dedicated line for data transmission. The difference between MSTP lines and the well-known Ethernet broadband is that it is transparent to users or routing devices. For users or routing devices, it is equivalent to directly pulling a network cable from the operator side, that is, Ethernet access. ...
