Feasibility Issues

Abstract

After specifying, evaluating, and optimizing our network architecture and protocol in the previous chapters, we now investigate the feasibility of the network. For the signalling of reservation requests we adopt a previously reported realization of spectrum spreading. In Section 8.1, we examine the impact of the transmission impairments of Section 1.2 on the transmission limitations of the network. In Section 8.2, we investigate by means of simulations the throughput-delay and packet loss performance of the network using the aforementioned signalling approach. Unlike the analyses and supplementary simulations of Chapter 6, we do not assume Bernoulli traffic in the following simulations. Instead, we use packet header trace files which were recorded at the metro level. The obtained results are discussed in Section 8.3. Section 8.4 provides some conclusions.
