Abstract:
An apparatus comprising a node configured to communicate with a path computation element (PCE) and a neighbor node, wherein the node is configured to send a local traffic engineering (TE) information directly to the PCE without sending the local TE information to the neighbor node. Also disclosed is a network component comprising at least one processor configured to implement a method comprising establishing a PCE protocol (PCEP) session with a PCE, and sending a TE information directly to the PCE without flooding the TE information. Also disclosed is a method comprising receiving a TE information, updating a first TE database (TED) using the TE information, and synchronizing the first TED with a second TED.
