摘    要:本文通过对现有网络中服务类别的分析、归纳,针对现有的分层网络体系结构存在的层间功能重叠和复杂的分层处理过程所带来的网络服务效率低下的问题,提出了一种基于服务元的网络体系结构.服务元只提供服务,不接受服务,所以避免了层间交互和服务传递的开销.服务元不仅能为本节点应用提供服务,而且不同节点的服务元可以合作向某一节点或整个网络提供服务.本文给出了微通信元系统构架,它是一种易于从TCP/IP过渡的服务元网络体系结构的构架.作为微通信元的服务元被组织成微通信系统,大量的微通信系统被组织成网络系统.微通信元系统构架具有简洁、可扩展和容易实现的特点.

关 键 词:网络体系结构  层次结构  面向对象  服务元  微通信元

Abstract:Based on the analysis of network services and the deficiency in current layered network architectures caused by multi-layer functional duplication and complicated processing,this paper proposes a Service Unit based Network Architecture (SUNA).Service Unit (SU) only provides services,and does not receive any services,thus it avoids inter-layer interactions and costs of delivering services.SU provides services for local node applications,and SUs of different nodes can also collaborate to provide services for the entire network or a certain node.Furthermore,the Micro-communication Element System (MCES) is presented for SUNA,which is easy to be transitted from TCP/IP.Micro-communication System is constructed of organized Micro-communication Elements which are equal to SUs,and network system consists of many Micro-communication Systems.MCES is easy to design and implement and has greater flexibility.
Keywords:network architecture  layered architecture  object-oriented  service unit  micro-communication element
