Abstract

The present invention is directed towards systems and methods of routing payload data in a communications system. Specifically, the payload data is routed using a source address. The destination node(s) utilize a dynamically-stored look-up table indicating the source address when the payload data is to be dropped at that node(s).

Claims (9)

1. A communications system for routing data throughout multiple rings, the communications system comprising:

a source node having a source address and a source ring, the source node for routing payload data including the source address and the source ring along with a VLAN tag;

a first destination node on a destination ring, wherein the VLAN tag is associated with the destination ring, the first destination node for receiving the payload data, wherein the first destination node receives the payload data based on the source address, the source ring, and the VLAN tag;

a connecting node on the source ring for inserting the VLAN tag;

an ingress connecting node on the destination ring, the ingress connecting node for stripping the VLAN tag from the payload data, and for routing the payload data, the source address, and the source ring; and

an egress port on the first destination node for stripping the source address and the source ring from the payload data, and for providing the payload data to a connected device.

2. The communications system of claim 1 , wherein the connecting node replicates the payload data, the source address, and the source ring and provides a second VLAN tag for routing to a second destination node.

3. The communications system of claim 1 , wherein the first destination node comprises a table including fields specifying the source address and the source ring.

4. The communications system of claim 1 , wherein the second destination node comprises a table including fields specifying the source address and the source ring.
