CONTROLLING BURST LOSS RATIO IN OBS USING FEEDBACK CONTROL AND DYNAMIC TECHNIQUES
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 1
Abstract
Optical Burst Switching(OBS) is a switching technique used in optical network where data is sent as bursts. In this switching technique single burst loss can influence loss of multiple data. Hence Burst Loss Ratio (BLR) is the main deciding factor for determining the performance of an OBS network. This paper proposes two level schema by which BLR can be reduced. The first algorithm proposes a closed loop feedback technique in which the destination node senses the data traffic and sends feedback to the source node. The second algorithm provides a link protection and restoration mechanism by providing suitable backup channels by using Label-Stacking and Burst-Multiplexing Techniques. This work provides service level objectives in terms of burst loss ratio (BLR), while guaranteeing QOS requirement of each class of bursts
