服务动态扩展网络及其结点系统模型的实现

Implementation of service dynamic extended network and its node system model

为有效提升网络服务能力,可扩展网络服务模型(ENSM)将网络服务内涵从承载网拓展到整个网络,定义了一种以协议元功能单元动态部署及动态组合为基础的统一服务扩展模型,可有效提高网络服务能力及服务扩展能力。本文基于ENSM原理提出服务动态扩展网络(SDEN),并结合SDN、NFV等新型网络架构设计思想对其结点模型及关键机制进行研究,设计并实现了SDEN结点系统,通过路由服务的定制和动态扩展,验证SDEN结点系统设计方案可行性及其对可扩展网络服务模型的良好支持。

To effectively enhance network service capability,Extensible Network Service Model(ENSM)extends the connotation of network services from bearer network to the entire network,and defines a unified service extension model based on dynamic deployment and combination of protocol meta-functional units,which can effectively improve network services capacity and service expansion capacity.In this paper,a new network called Service Dynamic Extended Network(SDEN)is proposed based on ENSM.Combined with the network architecture idea of SDN and NFV,SDEN node system model is researched and designed.In addition the experiment based on customization and dynamic expansion of routing services is implemented on a simple SDEN node system which turned out that the SDEN node system is feasible and has good support for ENSM services extensibility.
