N2 - Recent studies on inter-domain DWDM networks have focused on topology abstraction for state summarization, i.e., transforming a physical topology to a virtual mesh, tree or star network. Although these schemes give very good inter-domain blocking reduction, associated inter-domain routing overheads are significant, particularly as the number of domains and border OXC nodes increase. To address these scalability limitations, novel routing update triggering policies for multi-domain DWDM networks are developed. The performance of inter-domain lightpath RWA and signaling schemes in conjunction with these strategies is then studied in order to gauge the overall effectiveness of these approaches.
