Abstract
A method for dynamic ingress to egress tunnel mapping from a first communication network to a second communication network includes receiving a tunneled communication from a subscriber using the first communication network, determining egress tunnel selection criteria for the tunneled communication, selecting one of at least one egress tunnel based on the egress tunnel selection criteria and forwarding the tunneled communication on the selected egress tunnel. The egress tunnel selection criteria indicate the basis for selecting one of the egress tunnels. An apparatus for dynamic ingress to egress tunnel mapping from a first communication network to a second communication network includes a receiving interface to receive a tunneled communication from a subscriber using the first communication network, an egress tunnel selection criteria determiner to determine egress tunnel selection criteria for the tunneled communication, an egress tunnel selector to select one of at least one egress tunnel based on the egress tunnel selection criteria and a session forwarder to forward the tunneled communication on the selected egress tunnel. In one aspect of the invention, tunnel mapping is performed between Layer 2 Tunneling Protocol (L2TP) ingress and egress tunnels.
