Blocking analysis of dynamic lightpath establishment based on multistates reservation for wavelength-routed networks

Abstract

Two methods of reservation namely ANIR (all nodes-initiated reservation) and MSR (multi-states reservation) are proposed and compared with SIR (source-initiated reservation) and DIR (destination-initiated reservation). The four methods of reservation are simulated in NSFNET and ARPA topologies. Numeric results show that the blocking probability of ANIR is lower than SIR, but the number of packages which it generates is larger, and the blocking probability of MSR is lower than DIR and SIR under light load.
