Method for setting up notification function for route selection according to border gateway protocol

Abstract

After selecting BGP route sent from neighbor, border gateway sends an informing message for route selection to sender of route. The message includes target address of selected route and address space of local autonomous system. The sender stores information in received message for route selection to information database of route selection in concentration. Thus, inspection standard for packet address needed for method of filtering packets is generated. Route selection clock is added to informing function of route selection. Through route selection clock setup, sender waits for informing message for route selection form downstream autonomous system and gets information from message. Educational examination of simulation software proves that route selection clock decreases overhead of communication and processing overhead of router effectively under condition of not affecting on convergence rate of selecting information.

Description

technical field [0001] The invention belongs to the technical field of computer network routers. Background technique [0002] With the rapid development of the Internet, more and more applications are attracted to the Internet, and the next-generation Internet must be more trustworthy in order to carry a variety of security-sensitive applications. Web users' expectations of Internet service providers are also rising, especially in the financial sector, where consumers are shifting from traditional methods to businesses such as electronic payments and online banking. Various untrustworthy threats from the network, especially malicious attacks, such as distributed DoS, will bring huge losses to network users, so ISPs are under great pressure to improve their capabilities to prevent, monitor and mitigate various threats. hazards. The need for the Internet to provide trusted services is becoming more and more urgent, and the routing system needs to provide support for this. ...

AI Technical Summary

Problems solved by technology

The current routing protocol can only provide routers with information about how to forward packets, but does not provide support for information about which interface the packets should enter from.
