Claim:
1. A method comprising: receiving, by a path computation element from a client application, a path request that specifies two endpoints of a network, the two endpoints comprising an ingress endpoint and an egress endpoint; computing, by the path computation element and in response to receiving the path request, a path through the network to transport network traffic between the two endpoints from the ingress endpoint to the egress endpoint; and sending, by the path computation element to a router of the network that is the ingress endpoint, a message, wherein the message includes path information associated with each router along the path and traffic engineering information associated with one or more of the routers along the path, the message directing the router to establish, via a signaling protocol and based on the path information and the traffic engineering information received via the message, a traffic engineered label switched path (TE LSP) that traverses the path through the network to transport network traffic between the two endpoints from the ingress endpoint to the egress endpoint.
