Redirector, relay and route information configuration system and update method

Abstract

The invention discloses a system for configuring a redirection, a relay and route information and an updating method thereof; wherein the redirection comprises a route memory module used for storing route configuration information to each target node and a route indication module used for inquiring the route configuration information and generating route indication information which carries the route information according to the route configuration information, the route indication module is connected with the route memory module; the redirection also consists of a monitoring module which is connected with the route memory module and is used for monitoring the change of the route configuration information; a notifying module which is respectively connected with the monitoring module and is used for sending corresponding notice of route information invalidation of the changed route configuration information to a middle node which is managed by the redirection. By adopting the invention, when the route configuration information changes, the node can be notified that the previously subscribed route indication information is invalid, and the cached route information can be automatically, rapidly and timely updated, which ensures a correct forwarding of the service request information and improves service quality.

Description

technical field [0001] The invention relates to a message sending technology in the communication field, especially a redirector, a relay, a routing information configuration system and an updating method. Background technique [0002] AAA refers to Authentication (authentication), Authorization (authorization) and Accounting (billing). Authentication, Authorization, and Accounting (AAA) has been the basis of network operations since its inception. The RADIUS (Remote Access Dial up User Service) protocol is one of the most commonly used authentication and accounting protocols at present. It is simple, secure, easy to manage, and has good scalability, so it is widely used. However, due to the defects of the protocol itself, such as UDP-based transmission, simple packet loss mechanism, no regulations on retransmission and centralized billing service, it is not suitable for the current network development and needs further improvement. Diameter (diameter, Diameter protocol is...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is: in the prior art, when the routing configuration information in the redirector changes, the nodes that have sent the redirection request message before cannot be notified, and can only wait for the redirection routing information to expire automatically and become invalid , which will lead to the interruption of the application and the degradation of the quality of service
