Abstract
We present the set of protocols and procedures that constitute
Inter-Domain Policy Routing (IDPR). IDPR includes the virtual
gateway protocol, the flooding protocol, the route server query
protocol, the route generation procedure, the path control protocol,
and the data message forwarding procedure.
