【摘要】 <正> 1 前言随着Internet与移动技术的飞速发展,使得Internet用户海量剧增。但是随着人们对高级应用要求的日益增加,对目前的Internet提出了更高的要求。众所周知,目前的网络还是一个尽力型服务的网络,这一网络对它所提供的服务基本上没有服务质量的保证。目前除了Internet IP数据网络之外,还存着许多其它的异质网络,像电信网络、移动网络以及电视网络等,而这些异质网络提供的服务彼此是相互独立的,不能进行互操作。可以说这些网络基本上还以网络孤岛的形式存更多还原

【Abstract】 Internet is best effort network, on the whole,it doesn’t provide any quality of service assurance for services. Especially. all kinds of stream media need more network performance and quality of service. Currently, because of existing many heterogeneous networks, such as telecommunication network, IP data network,mobile network and so on,in order to break off this heterogeneous network isolated complexion,research and development next generation network must be carried out,only by this way,can these isolated heterogeneous network be merged into an all IP network. This network will provide enormous services for service users,how to manage these services effectively is a topic proposed by next generation internet. [1] gave research status for service management and advance, this paper researches service management requirement for next generation Internet and workflow etc. and based on these technique,a service management architecture model is proposed. It consists of service access layer, service deployment layer, service providing layer, service mapping layer, policy control layer and network element managing layer. These layers coordinate to implement service management.更多还原
