Abstract
A method of circuit emulation over an IP interworking VLL, and related system, the method including one or more of the following: configuring a circuit emulation port with one or more logical interfaces; configuring one or more channels on each of the one or more logical interfaces; configuring the one or more channels with a destination IP address; configuring the one or more channels with a destination UDP port number; specifying an Ipipe VLL for each of the one or more channels; determining TDM traffic to go onto the specified Ipipe; packetizing TDM traffic; encapsulating the TDM traffic with encapsulation; inserting one or more packets of the TDM traffic into an IP interworking VLL; sending the one or more packets through the Ipipe; stripping the encapsulation from the one or more packets of the TDM traffic; and forwarding the one or more packets to a destination.
