基于现场总线的企业信息系统网络的服务体系结构

The Service Architecture of Enterprise Information System Based on Fieldbus

传统的TCP/IP技术由于只支持尽力而为型一种类型的服务,使它在基于现场总线的企业信息系统网络的应用中受到了相当大的局限性。阐述了在企业信息系统网络中引入了QoS控制的必要性,在IntServ的基础上通过简化服务体系模型,并且为了实现针对该类型局域网络的一些特殊要求对IntServ进行一定调整和补充,提出了一种适用于企业信息系统网络的QoS体系结构。

Traditional TCP/IP technology is limited to apply for enterprise information system based on fieldbus because it only supports best-effort service. It is expatiated on the necessity of introducing QoS into this network. Furthermore, It adjusts and complements IntServ for accomplishing special requirement of the network on the basis of IntServ and brings forward a new QoS architecture for the network.
