摘要:
针对多光纤链路的光网络,提出了三种带宽适配算法,以更有效地管理相邻设备之间的多根光纤,从而减少光纤使用成本和管理复杂度。根据多光纤链路的剩余带宽特性,提出了三种算法的基本思想,然后在基于多光纤链路的MPLS网络中利用LCRA算法来验证三种算法的性能。三种算法在实现负载均衡、提高网络资源利用效率的同时各有其适用场合。仿真结果表明MFA算法有更低的请求拒绝率,更有利于带宽较小的业务的适配;而BFA和FFA算法更利于带宽较大的业务的适配,但请求拒绝率较高
Abstract:
For optical network of multi-fiber links,three bandwidth adaption algorithms were proposed to manage the fibers between adjacent devices more effectively.Thereby reduce the cost of fibers and managing complexity.First of all,the basic idea of the three algorithms was proposed according to the remaining bandwidth of multi-fiber links.Then the performance of three algorithms were verified in the MPLS network of multi-fiber links using LCRA algorithm.The three algorithms has its own application while balancing overall load and improving resource utilization efficiency.Simulation results show that the MFA algorithm has a lower rejecting rate,more conducive to small traffics to adapt;The BFA and the FFA algorithms is more conducive to traffic of greater bandwidth,but has a higher rejecting rate
