Abstract
Methods and computing systems for tunneling in a carrier transport network are described. An Internet Protocol (IP) packet having a destination IP address of a destination cellular site of a cellular cluster is received. A frame is formed with the IP packet placed into a payload portion of the frame. An outer Virtual Local Area Network (VLAN) tag that identifies a network of the cellular cluster to a first carrier network is added to the frame, and an inner VLAN tag that identifies the network of the cellular cluster to a second carrier is added. The first carrier network and the second carrier network are coupled via at least one network-to-network interface. The frame, including the IP packet, is forwarded to a provider edge switch of the first carrier network.
