| Abstract: | As the need of network user for high-availability is increased, how to evaluate the network availability justly becomes an on edge problem. Network availability is studied from life of hardware aspect. We find that availability and blocking ratio are usual contradictory in WDM networks, and make a practical and scientific network availability definition, which is the threshold availability value compare blocking ratio. We proposed a Dynamic Network Availability Algorithm (DNAA) in WDM networks to get the network availability. It is practical to user and operator of network. Simulation results show that DNAA is not only correct but also efficient. |
