1. A method for performing resource allocation and admission control of virtual private networks in a communications network with a plurality of customer endpoints and a plurality of provider edge routers, comprising:
- receiving a new customer virtual private network request; and
determining whether to admit or reject the new customer virtual private network request based upon available capacity information for paths between the plurality of provider edge routers and customer traffic between the plurality of customer endpoints and the plurality of provider edge routers, wherein the determining comprises;
provisioning edge resources to optimize routing table sizes and a backhaul distance upon receiving the new customer virtual private network request; and
computing an initial customer traffic matrix using customer specified peak rate traffic information and the available capacity information.
