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