Abstract
A method and system for communicating traffic on an emulated subnetwork of a telecommunications ring having a plurality of nodes interconnected by a transmission media includes obtaining traffic at a node on the telecommunications ring. The traffic is segmented into a plurality of discrete segments. A set of broadcast cells is generated by adding an address header to each segment. The address header identifies a virtual channel dedicated to the node on the subnetwork in the telecommunications ring. The set of broadcast cells are transmitted in the virtual channel of the subnetwork and within a frame of the telecommunications ring. At each remaining node on the telecommunications ring, in response to receiving the set of broadcast cells in the virtual channel, both retransmitting and processing the broadcast cells.
