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.
