Abstract
There is an increasing need for many media gateway nodes to be used in enterprise networks. These media gateway nodes are typically connected behind a network address translator (NAT) which connects the enterprise network to a public communications network. Communication between the access nodes and a service provider network, which is also connected to the public network, is needed to provide communications services to end users. However, as the number of media gateways increases problems arise associated with increased traffic, complexity and use of resources at the NAT and at the service provider network. A solution is presented whereby a node is used to represent the media gateway nodes in the enterprise network.
