摘要
对网络体系结构的研究现状进行了介绍.基于MCES(micro-communicationel ement structure)架构设计了一种基于服务的网络体系结构原型.在原型系统中,实现了服务元的合理组合和调度,并从体系结构上更好地支持QoS和网络安全.同时,通过改进的套接字机制实现了向后兼容现有TCP/IP网络应用程序,满足了用户不断增长的网络服务要求.基于Linux的实验结果显示,该体系结构组成的系统是合理的、可行的,并具有很好的传输效率和可扩展性.
The state of the art of network architecture is presented. Based on a micro-communication element structure （MCES）, a service-based network architecture prototype is implemented, in which service units are scheduled and assembled logically. While supporting QoS and ensuring network security more effectively, the prototype can be compatible with all existing TCP/IP applications by an improved socket design. The experimental results show that the prototype of service-based network architecture is feasible, and possesses good transmission efficiently and scalability.
