可扩展网络服务模型的服务扩展能力分析

Analysis of service extensible capability for extensible network service model

网络的服务扩展能力是下一代网络的重大需求,也是网络服务模型技术发展的主要挑战。可扩展网络服务模型正是应网络发展的这一需求而提出的。概述了该服务模型的基本概念与原理;从原理分析的角度对该服务模型的服务扩展能力进行了定性分析;使用网络服务扩展能力的分析方法,从理论和网络实际应用2个角度选用实例对该服务模型的服务扩展能力的进行了定量分析。由定性分析与定量分析结果可知,可扩展网络服务模型具有很好的服务扩展能力。

The capability of providing network service extensibility is the major demand of next generation network, it is also the main challenge of network service model technology. The extensible network service model was proposed in re- sponse to the demand of network development. Firstly, an overview of the basic principles of the extensible network ser- vice model was expounded. And then, from the point of view of principle analysis, the service extension capability of the service model was qualitatively analyzed. Finally, using the analytic method of network service extensible capability, the service extension capability of the service model was quantitative analyzed from two perspectives of theory and practical application. The qualitative analysis and the quantitative analysis show that the extensible network service model has strong service extensible capability.
