摘要: 在承载于WDM的IP网中,波长电路通常具备备用电路,在多数时间内该备用电路处于空闲状态,造成了资源浪费。日益增长的带宽需求对传输网造成了巨大的压力,增大空闲备用电路的利用率十分必要。本文提出了一种IP网络与波长业务共享容量的可生存网络设计,通过使用一种高效的启发式算法,在保证IP网络可生存性的状况下,将波长电路的空闲备用电路合理分配给IP网络。实验结果表明,通过波长电路与IP网络共享空闲备用电路,能够实现更高的资源利用率,在保证其生存性的同时降低网络成本。
Abstract: In the IP over WDM networks, wavelength circuits typically have backup circuits which are often idle. This situation causes a lot of waste of resources. The growing bandwidth demand puts large pressure on the transmission network, so it is necessary to increase the utilization of idle backup circuits. In this paper, we propose a survivable network design with capacity sharing between IP and wavelength service. An efficient heuristic approach is presented. This approach allocates the idle backup wavelength circuit to the IP network while ensuring the survivability of the IP network. We observe that sharing idle backup circuits with IP traffic enables higher resource utilization. The approach ensures its survivability while reducing network cost.
