Abstract:
1. A method of circuit emulation over an Internet Protocol (IP) interworking Virtual Leased Line (VLL) to enable a circuit emulation port having non-Ethernet technology to connect to an Ethernet port, the method comprising: configuring the 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 User Datagram Protocol (UDP) port number; specifying an Ipipe VLL for each of the one or more channels; determining Time Division Multiplexed (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 the 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; generating an Address Resolution Protocol (ARP) request, wherein the ARP request specifies a circuit emulation device as a destination and an IP address of the circuit emulation port as a source; and forwarding the one or more packets from the Ethernet port to an IP destination.
