A Performance Overview of Quality of Service Mechanisms in Optical Burst Switching Networks
This Chapter addresses the problem of quality of service (QoS) provisioning in optical burst switching (OBS) networks. OBS is considered as a very promising mid-term solution for the next-generation optical networks. The lack of optical memories, however, makes the operation in such networks quite complicated, especially in case when one wants to guarantee a certain level of service quality. In...
متن کاملEarly drop and wavelength grouping schemes for providing absolute QoS differentiation in optical burst-switched networks
A number of schemes have been proposed to support QoS in optical burst-switched (OBS) networks. Most schemes only support relative QoS differentiation instead of absolute QoS guarantee. However, absolute QoS differentiation is a basic requirement for many delay and loss sensitive applications. In this paper, we propose two mechanisms for providing absolute QoS differentiation in OBS networks, a...
متن کاملSTSM Scientific Report
The purpose of this short scientific mission was to initiate a joint UST and UPC research work focusing on QoS management in OBS networks. Particularly, a framework for QoS management architecture have been discussed and proposed during the stay in Stuttgart. The main stress was put on definition of Classes of Quality (CoQ) for OBS networks and performance evaluation of selected QoS mechanisms....
متن کاملBuffer and Bandwidth Allocation Algorithms for Quality of Service Provisioning in WDM Optical Burst Switching Networks
Optical Burst Switching (OBS) has been developed as an efficient switching technique to exploit the capacity provided by Wavelength Division Multiplexing (WDM) transmission technology for the next generation optical Internet. One critical design issue in OBS is how to provide Quality-of-Service (QoS) in optical networks. This thesis focuses on providing QoS in OBS networks. Two basic models for...
متن کاملA Fuzzy Based Three Color Meter/Marker for Diffserv Networks (RESEARCH NOTE)
Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF, meters an IP packet stream and marks its packets either green, yellow, or red....
