Intelligent Deflection Routing Protocol
نویسنده
چکیده
Contention is the main source of burst loss in Optical Burst Switched (OBS) networks where deflection routing is one of the methods to resolve contention. Deflection routing requires enhancements only in the routing software without additional hardware installations. Its main goal is to successfully deflect a burst based only on a limited knowledge that nodes posses about their environment. In this paper, we present an intelligent deflection protocol named iDef. The iDef enhances a node with intelligent decision making ability through a Monte-Carlo planning algorithm, which employs a forward search to select the best output interface for a burst to be deflected. The proposed iDef design enables a node to adapt itself to changes in network topology and traffic patterns.

A deflection routing algorithm that can be applied to a novel self-routing address scheme for networks with arbitrary topology is proposed. The proposed deflection routing algorithm can be implemented all-optically using bitwise optical logic gates. Besides the primary output link selection, alternate output link choices by a packet at each node in case of deflection are also encoded in the add...
متن کاملPerformance Evaluation of Combined Buffering and Deflection Routing in Hierarchical Ring Interconnection Networks
Buffering and Deflection routing are two commonly methods used in resolving packet contention in the crossbar switches between levels in a hierarchical ring interconnection networks. However, each method is limited its own ways. To improve the performance, we propose a new hybrid routing algorithm which uses both buffering and deflection. Our extensive simulation results show that this combined...

In this work we study the OSPF protocol focussing our attention on the multi-area architecture. The target of the work is to model the multi-area OSPF and to analyze the complexity it introduces in the intra-domain routing. To make this we propose a model of the OSPF protocol. The aims of the model is to discover the routing choices performed by the routers without reproducing the exchange of i...
متن کاملContention-based limited deflection routing in OBS networks
One of the critical design issues in Optical Burst Switching (OBS) networks is finding ways to minimize burst dropping resulting from resource contention. The existing variants of the basic deflection routing schemes all lack the ability to determine the alternate route based on clear performance objectives. In this paper, we present Contention-Based Limited Deflection Routing (CLDR) scheme, wh...
