一种网络服务可扩展性分析方法研究

摘要

服务可扩展性是网络研究中一种非常重要的属性，它的优劣决定着网络系统未来的可用性。综合现有的网络服务可扩展性及其分析方法所面临的问题，用统一的描述方式将不同的网络系统的服务行为抽象为服务拓扑模型，用统一的评价模型进行服务可扩展性分析，以便能够对不同的网络系统进行比较全面而正确的可扩展性评价。利用该可扩展性分析方法对网络路由系统进行实验建模，使用 NS2对实验模型进行仿真实验，验证其适用性和优越性，为进一步研究新型网络及其扩展性提供可靠依据。%Service scalability is a very important attribute in network research.The quality of service scalability determines the availability of network in the future.This paper colligates the problems encountered by current scalabilities of network services and their analyses methods,uses uniform description means to abstract the service behaviours of different network systems as the service topology models,and then analyses the services scalability by unified evaluation model,so as to carry out rather comprehensive and correct evaluation on the scalabilities of different network systems.Moreover this scalability analysis method is used in experimental modelling of network routing system,and the NS2 is employed to carry out simulation experiment on experimental model to verify its applicability and superiority.This provides the reliable basis for the further research of novel networks and their scalability.
