Abstract:
A redirector, a relay and a routing information configuring system and an updating method are provided. The redirector includes: routing storing module, which is used to store the routing configuration information to each destination node, and the routing indication module connected to the routing storing module, which is used to search the routing configuration information and generate the routing indication information carrying the routing information based on the routing configuration information. It also includes: the monitoring module connected to the routing storing module, which is used to detect the change of the routing configuration information, and the notification module connected to the monitoring module, which is used to transmit the invalidation notification of the routing information corresponding to the routing configuration information to the medial nodes managed by the redirector. Using the scheme above, when the routing configuration information changes, it can notify the node in good time that the routing indication information subscribed before has become invalid, and can also update the caching routing information automatically, fast and in good time, and it makes sure the correct forwarding of the service request and improves the service quality.
