An Optical Data Double Ring Network

Abstract

This paper proposes an optical ring network that can tap the optical bandwidth by eliminating performance bottlenecks associated with the electronic processing of transmitted data. The proposed network and node architecture address the issues of packet transmission control and resources contentions, such as link, transmitter, and receiver contentions, in networks which maintain the data in the optical format. The presented solution does not require multiple transmitters and receivers at each node to resolve contentions and offers route-through, fault-tolerant switches. Performance evaluation shows that this ring network can asymptotically achieve the ideal capacity of an all-optical contention free ring.
