Abstract
Embodiments of the present invention relate to the field of communications technologies, and disclose a performance-based routing method and device, which can implement exchange of a performance route by expanding a BGP protocol. A first PCR receives first performance routing information sent by a second PCR. The first performance routing information includes a first performance parameter attribute. It is determined whether a performance route corresponding to the first performance routing information exists in an adjacent routing information base-in Adj-RIB-in of the first PCR. The performance route is added to the Adj-RIB-in when the performance route does not exist in the Adj-RIB-in.
Claims20
A performance-based routing method, comprising:
- receiving, by a first PCR (performance-routing capable router), first performance routing information sent by a second PCR, wherein the first performance routing information comprises a first performance parameter attribute;
- determining whether a performance route corresponding to the first performance routing information exists in an adjacent routing information base-in Adj-RIB-in of the first PCR;
- and
- adding the performance route to the Adj-RIB-in when the performance route does not exist in the Adj-RIB-in.
A performance-based performance-routing capable router (PCR), comprising:
- a first performance routing information receiving unit, configured to receive first performance routing information sent by a second PCR, wherein the first performance routing information comprises a first performance parameter attribute;
- a determining unit, configured to determine whether a performance route corresponding to the first performance routing information exists in an adjacent routing information base-in Adj-RIB-in of the PCR;
- and
- a performance routing information storing unit, configured to add the first performance routing information to the Adj-RIB-in of the PCR when the performance route corresponding to the first performance routing information does not exist in the Adj-RIB-in of the PCR.
