PROJECT TITLE :

Enhancing Fault Tolerance and Resource Utilization in Unidirectional Quorum-Based Cycle Routing - 2018

ABSTRACT:

Cycle-based optical network routing, whether or not using synchronous optical networking rings or p-cycles, provides sufficient reliability within the network. Lightweight trails forming a cycle allow broadcasts inside a cycle for use for economical multicasts. Optimal communication quorum sets forming optical cycles based mostly on lightweight trails are shown to flexibly and efficiently route both purpose-to-point and multipoint-to-multipoint traffic requests. Commonly, cycle routing techniques use pairs of cycles to realize each routing and fault tolerance, which use substantial resources and create the potential for underutilization. Instead, we have a tendency to intentionally utilize R redundancy inside the quorum cycles for fault tolerance such that every purpose-to-point communication pairs occur in a minimum of R cycles. We have a tendency to develop a generalized R redundancy cycle technique that provides optical networks high fault-tolerant communications capability. When applied using solely the single unidirectional cycles rather than the standard paired cycles, the generalized R redundancy technique has been shown to virtually halve the mandatory lightweight-path resources in the network. However, due to unidirectional nature, a tiny percentage of node pairs for one-to-one communication may not have specifically two ways. For this reason, we tend to additional develop a greedy cycle direction heuristic and show a reduction of missing pairs. More importantly, we tend to show that the resource requirement is reduced while maintaining the fault tolerance and dependability expected from cycle-based mostly routing. The result is a set of cycles with 96.sixp.c-ninety nine.thirty sevenp.c fault coverage, while using forty two.9%-forty seven.eighteen% fewer resources.
