Patent ID: 7599302

Claim:
A method for dynamically enforcing inter-domain policy and quality of service (QoS) for Traffic Engineering (TE) Label Switched Paths (LSPs) between a local domain and a remote domain in a computer network, the method comprising: receiving a path computation request at a Path Computation Element (PCE) of the local domain, the path computation request for an inter-domain TE-LSP from the remote domain to the local domain; sending a policy verification request from the PCE to a Policy Decision Point (PDP) of the local domain, the policy verification request including one or more constraints of the inter-domain TE-LSP to be checked against configured policy for the remote domain and previously established TE-LSPs from the remote domain; and determining at the PDP of the local domain whether the TE-LSP is allowed based on configured policy for the remote domain and previously established TE-LSPs from the remote domain.
