Summary:
ISU researchers developed a novel method to enhance fault tolerance capabilities of cycles in the optical networks based on quorum set theory and light-trails.

Development Stage:
Description:
Optical networking is a high-speed communication that consists of multiple transmitters and receivers interconnected by fiber-optic cables. It integrates signals encoded onto light to transmit information among various nodes of a telecommunications networks. However, failures within a network are to be expected and can happened as much as every couple days. Protecting against these optical circuit faults is important and developing new methods with enhanced efficiency and distributed control is in demand. In a distributed system and algorithms, nodes are often grouped into intersection sets referred to as quorum sets to improve efficiency and distribution control. Using the same quorum set theory, ISU researchers found a method to accomplish the efficiency and distributed control in optical network routing. This method applies the distributed efficiency of the quorum sets to routing optical cycles based on light-trail. With this method, unicast and multicast communication requests do not need to be known or even modeled a priori. Furthermore, in the presence of network link faults, >99% average coverage enables the continued operation of nearly all arbitrary unicast and multicast requests in the network.

Advantage:
• Quorum-based cycles show efficiency and distributed control.
• This method is reliable and fault tolerant.
• Supports expected traffic (one-to-one or one-to-many traffic) efficiently.
• Creates fair and efficient resource utilization.
Application:
Optical network
