Resource Provisioning for Dynamic Multi-Domain WDM Networks: Effectiveness and Fairness
Source: University of Illinois
In this paper, the authors approach new problems of resource dimensioning and routing for multi-domain networks supporting future user-driven dynamic traffic. Three basic dimensioning approaches - independent, global, and normalized - are studied in conjunction with the appropriate routing schemes that match each dimensioning policy based on how much information is shared across domains. They quantify the performance of inter-domain and intra-domain traffic while considering changes in traffic loads as well as network rescaling. The authors introduce the notion of fairness, which raises questions about how network domains with separate ownership and possibly conflicting economic interests should decide on co-providing bandwidth-on-demand services.
