MPLS快速重路由(FRR)中的主路径和备份路径可以根据IP控制平面的管理链路成本被建立为最短路径,或者被建立为显式计算的任意路径。在这两种情况下,路径布局可以被优化,使得针对特定流量矩阵和针对一组所考虑的故障场景的最大链路利用率被最小化。在本文中,我们提出了一个线性规划的路径布局优化明确计算的路径,它可以产生单一的路径和路由整个流量沿着这些路径,或产生多个路径和传播这些路径之间的流量提供负载平衡。我们比较了这两种情况下的最低最大链路利用率最低的最大链路利用率,可以通过优化独特的基于IP的路径。我们的研究结果量化了优化的显式多路径或显式单路径相比,优化的基于IP的路径提供的资源效率使用的增益。此外,我们调查,如果显式路径布局会导致增加配置工作相比,基于IP的布局,如果是的话,到什么程度。
Primary and backup paths in MPLS fast reroute (FRR) may be established as shortest paths according to the administrative link costs of the IP control plane, or as explicitly calculated arbitrary paths. In both cases, the path layout can be optimized so that the maximum link utilization for a specific traffic matrix and for a set of considered failure scenarios is minimized. In this paper, we propose a linear program for the optimization of the path layout for explicitly calculated paths, which can either produce single paths and route entire traffic along those paths, or generate multiple paths and spread the traffic among those paths providing load balancing. We compare the resulting lowest maximum link utilization in both cases with the lowest maximum link utilization that can be obtained by optimizing unique IP-based paths. Our results quantify the gain in resource efficiency usage provided by optimized explicit multiple paths or explicit single paths as compared to optimized IP-based paths. Furthermore, we investigate if explicit path layouts cause an increased configuration effort compared to IP-based layouts and if yes, to what extend.
