QoS Resource Reservation Mechanisms for Switched Optical Networks

Abstract

The paper regards the problem of resource reservation mechanisms for Quality of Service support in switched optical networks. The authors propose modifications and extensions for resources reservation strategy algorithms with resources pools, link capacity threshold and adaptive advance reservation approach. They examine proposed solutions in Automatically Switched Optical Network with Generalized Multi-Protocol Label Switching named as ASON/GMPLS network. The analysis is performed by simulation the Polish network structure with the use of OMNeT++ discrete-event simulator.
