GMPLS网络中的多元故障传播模型

摘要

现有流行病传播模型的应用范围仅限于一元故障或同构网络.为此,提出一个通用多协议标志交换(GMPLS)网络中的多元故障传播模型.将网络节点功能分为控制层和数据层,并给出故障传播阈值的计算公式.使用不同的拓扑结构进行模拟实验,结果均接近于理论值,验证了该模型的正确性.%Existing epidemic spread models are only used in unitary failure and homogeneous network. Aiming this problem, this paper presents a multiple failure spread model in Generalized Multiprotocol Label Switching(GMPLS) network. This model assign node functions into two planes: control plane and data plane. The math formulation for finding the epidemic threshold is given. Extensive simulations is carried out on different network topologies, the results are approach to the theoretical values, which show this model is exact.
