A Hierarchical Backbone Network Based on VLB Architecture
Rui Li, Jianya Chen, Yunjie Liu, Tao Huang · 2010
The increasing growth of the global Internet making the shortcomings of its unstructured topology and distributed routing algorithm are exposed more rapidly. To design a controllable, scalable and manageable backbone network with a simple, efficient architecture is very imperative. Among many topologies, Tree topology which has a natural hierarchical structure and explicit end-to-end transmission path provides a promising solution for the future Internet architecture. To overcome the defects of tree topology in reliability and scalability, we propose a hierarchical network based on Viliant load-balancing (VLB) architecture which takes advantage of the both. The analysis of its fault-tolerance property and the corresponding flow-level load-balancing scheme are also presented in the paper.
