动态拓扑下的可重构服务承载网资源迁移方法

Resource migration scheme for reconfigurable service carrying network under dynamic topology condition

提出了动态网络模型分析承载网资源迁移问题,并引入了迁移效率概念,设计了资源迁移方法。该方法以元请求迁移过程为基础,分别针对拓扑收缩和增长情况提出资源容错迁移和资源均衡迁移两种算法。仿真结果表明,基于迁移效率的资源迁移方法提高了请求接受率和负载均衡度,同时降低了迁移代价。

This paper proposed a dynamic network model to analyze the RSCN resource migration problem,and introduced a concept of migration efficiency to design a resource migration scheme.This scheme included two algorithms based on atomic request migration procedures,which were resource fault-tolerant migration and resource balanced migration respectively focusing on topology contraction and growth.Simulation results show that the migration-efficiency-based resource migration scheme（ME-Mig） increases the request accepted ratio and the network load balance degree,while decreasing the cost of RSCN＇s migration.
