DEFLECTION ROUTING IN BUFFER-LESS NETWORKS

Performance and analysis using ns-3

ABSTRACT

In Buffer-less networks such as Optical Burst Switch (OBS) that are high-bandwidth backbone networks (Ethernet interfaces of 40 Gigabit Ethernet and 100 Gigabit speed [1]), packets are assembled into bursts that are transmitted over optical fibers [2]. Burst blocks or burst drops occur due to contention in these complex networks [3]. Contentions occur when the buffer space is unavailable for packet bursts that are scheduled for transmission [4]. Deflection routing is used to deflect the traffic flow to a different next-hop [5]. In this project we plan to study the performance of Deflection Routing in resolving packet contention problems in complex networks such as OBS using ns-3 network simulator [6].

We would like to thank our advisor Dr. Ljiljana Trajkovic for all her guidance and continuous support throughout this project. We would like to thank you for encouraging our study and opening the doors of an amazing lab where we met wonderful, smart, and committed people. Your advice on both, study as well as on our career have been priceless. We are also deeply grateful to our Teaching Assistant Zhida Li for the brainstorming discussions and guidance. We have learned so much from you. We also want to thank and acknowledge Dr. Soroush Haeri and Dr. Ljiljana Trajkovic for the iDef Framework and the source code that we studied and ran test cases for computing the performance of Deflection Routing algorithms.
