Abstract:
1. A method for providing transparent LAN services over a ring network, the ring network including a plurality of nodes and domains, the method comprising: receiving a first data packet at one of the plurality of nodes on the ring network, wherein a source device of a domain transmits the first data packet, further wherein the first data packet includes a destination MAC address and a MAC address of the source device; appending a ring header, a service header, and a multicast MPLS label to the first data packet to form a ring packet, wherein the service header includes a unicast MPLS label and a source IP address, further wherein the multicast MPLS label is associated with the domain only; maintaining a table that associates both the unicast MPLS label and the source IP address of the service header of the ring packet with the MAC address of the source device; and transmitting the ring packet onto the ring network to be multicast to at least another device of the domain associated with the multicast MPLS label.
