Disclosed are a path selection method and device, a routing bridge, and a network. The method comprises: obtaining a current network load parameter of a first routing bridge in a Transparent Interconnection of Lots of Links (TRILL) network; sending link state overload notification information to all other routing bridges in the TRILL network when the network load parameter exceeds a corresponding preset overload threshold; instructing all other routing bridges to mark the first routing bridge as unreachable state, and calculating a shortest path in paths from all other routing bridges to the routing bridges in the TRILL network again. With the technical solution of the present invention, a current network load parameter of a routing bridge in a TRILL network is detected in real time, and when the routing bridge is overloaded, other routing bridges are actively notified, so as to enable the other routing bridges to perform path selection operations again, thereby avoiding problems of packet loss and delay caused by an excessively heavy load on a particular routing bridge, and improving reliability of the TRILL network to some extent. |
