随着网络用户对网络的可用性要求越来越高,如何较公正地评估网络的可用性成为迫切的问题。该文对WDM网络在动态业务情况下提出了一种网络可用性算法,并定义了网络的运行性能等于网络的业务接受率乘以业务要求的可用性。该算法在保证网络具有最好的运行性能下获得最高的网络可用性。最后对所提算法进行了仿真,验证了其正确性。
As the need of network user for high-availability is increased, how to evaluate the network availability just becomes an on edge problem. Then a Dynamic connections Network Availability Algorithm (DNAA) in WDM network is proposed, which considers high network performance, and the network performance is defined as that the accept rate multiplies the required availability of users. Simulation results show that DNAA is not only correct but also efficient.
