摘要
结合广电网大容量的发展要求,考虑较为复杂的网状网结构,网络生存性问题日益凸显。对经典的预置圈(P圈)容量算法进行了改进,并选用COST239网络拓扑对改进算法进行编程仿真。结果证明,改进算法在减少预置圈数量的同时能够提高资源利用率,性能有所提高,可以较好地解决广电网的生存性问题。
Combined with the large capacity requirement of broadcast＆TV network, in view of more complex mesh network, survivability is important to large capacity OTN network. In this paper, the classical P-cycle capacity assignment algorithm-CIDA is improved and the algorithm is simulated by using the COST239 network topology. The simulation results show that the improved algorithm has brought about better resource utilization and less P-cycles. The performance has been improved. Thus the improved P-cycle algorithm can better solve the survivability problem of large capacity broadcast ＆TV network.
