Abstract
Disclosed are a path computation element communication protocol (PCEP) session establishment method and device. The technical solution comprises: at a PCC or PCE node device side, before needing to establish a PCEP session, allocating a TCP connection communication end attribute to a PCC or a PCE at either end in the manner of static configuration/dynamic designation or election mechanism automatic allocation; or detecting whether to establish a TCP connection relationship, if not, actively connecting the opposite end, and if a plurality of TCP connection relationships has been established, simultaneously cutting off a plurality of connections at both ends, and reinitiating a TCP connection after waiting a random time respectively. The present invention achieves the establishment of a PCEP session in the multi-PCE cooperation computation scenario under the condition of meeting two constraint conditions which are specified by a protocol.
