Problems in Dynamic Bandwidth Allocation in Connection Oriented Networks

Chapter

Abstract

In this chapter, the analysis of the problems emerging from dynamic bandwidth allocation in connection-oriented packet networks is considered in a multilayer scenario, considering IP protocols on top of an MPLS network over an OBS optical network. The issue (and problem) is to maintain and ensure the end-to-end in-sequence routing of packets, combining load balancing in packet switching architectures and bandwidth/flow allocation in MPLS-based architectures to establish the ordering of packets. If load balancing can be achieved by switches or routers, this can greatly facilitate applying load balancing across the network. Traffic characteristics such as QoS (delay bounds, throughput) and burstiness are considered.
