一種基于運行性能的網(wǎng)絡可用性算法
A Network Availability Algorithm Considering Network Performance
-
摘要: 隨著網(wǎng)絡用戶對網(wǎng)絡的可用性要求越來越高，如何較公正地評估網(wǎng)絡的可用性成為迫切的問題。該文對WDM網(wǎng)絡在動態(tài)業(yè)務情況下提出了一種網(wǎng)絡可用性算法，并定義了網(wǎng)絡的運行性能等于網(wǎng)絡的業(yè)務接受率乘以業(yè)務要求的可用性。該算法在保證網(wǎng)絡具有最好的運行性能下獲得最高的網(wǎng)絡可用性。最后對所提算法進行了仿真，驗證了其正確性。Abstract: 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.
