Blocking Analysis of Dynamic Lightpath Establishment based onMulti-states Reservation for Wavelength-Routed Networks

摘要

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