Performance Evaluation of the Loop Buffer Switch under Prioritized Traffic

By Devesh Pratap Singh Rajiv Srivastava

DOI: https://doi.org/10.5815/ijitcs.2013.05.08, Pub. Date: 8 Apr. 2013

In this paper, optical loop buffer based architecture is discussed; with its advantages over other architectures. In general the performance of the switch is measured at physical and network layer. The physical layer analysis deals with power budget analysis, however, at the network layer; the performance is measured in terms of packet loss probability and average delay. To obtain more realistic performance at the network layer the QoS parameters need to be included. In this paper, a QoS parameter which is known as priority of the incoming packets is included and corresponding results are presented, and it has been found that even at the load of 0.7, packet loss probabilities on the order of 10-5 can be achieved.

Performance Evaluation of the Loop Buffer Switch Under Prioritized Traffic and Optical Regeneration

By Devesh Pratap Singh Rafik Ahmad Rajiv Srivastava

DOI: https://doi.org/10.5815/ijitcs.2013.01.04, Pub. Date: 8 Dec. 2012

In this paper, an all-optical regenerator based, photonic packet switch architecture, which consists of the fiber loop for the storage of the contending packets, is considered. In the loop buffer, the available buffer space may not be fully utilized due to the limited re-circulation count of the data placed on buffer. This limit can be counteracted by placing a pool of regenerators inside the buffer. As optical regenerators are costly devices, hence they should be placed optimally in the buffer. The simulations results are presented by consider Prioritized and non – prioritized traffic. It is shown in the results that regeneration of data is essential if prioritized traffic has to be considered.
