ISM:Intent-Perceptible Service Migration Model for IP Network Survivability
本文提出了一种漂移意图可感知的IP网络生存性服务提供模型(Intent-perceived Service Migration
ISM).在ISM模型中
我们设计了一种独特的服务漂移触发机制和目标节点选取策略
并通过服务器与客户端的协作
使客户端对服务器集群内部的服务漂移意图有了预感知能力.分析结果表明
ISM模型既能在时间和空间上保证服务漂移的随机性
增强服务抗毁度;又能显著减小由服务漂移带来的服务间断时间
有效提高了IP网络服务可生存性.
Abstract
The existing service migration methods bring the server cluster heavy burden
and their time spending is so high that seriously affects the service continuity.In order to enhance the survivability of IP network services
the paper puts forward an intent-perceptible service migration model (ISM).In this model
we design a novel trigger mechanism and object selecting method for service migration
and make the service migration intention perceptible for the client with the cooperation of the server.The evaluation results show that ISM model can not only ensure the service invulnerability by maintaining a high randomness of service migration
but also improve the service continuity by reducing the service gap time spending on service migration to the maximum extent.Therefore
ISM model can enhance IP network survivability efficiently.
