【Abstract】 Internet is currently evolving from a best effort only service towards a service that supports different levels of Quality of Service. Especially,with IPv6 becoming mature and Telecom network,Internet network and wireless mobile network are merged into an all IP network. In the future,Internet will be a network-service-driven. This integrated all IP network will provides tremendous services with service users. Therefore, it will be important to effectively manage these services both for service providers and service users. For service providers, providing high QoS with service users,They can earn much high profits. For service users,they can obtain all kinds of abundant different level QoS to meet their needs,at anytime and anywhere. In this paper,service management technique progresses are overall surveyed,different organization service management models are surveyed,including their principle and application scenario. Finally,all these service management models are compared. Interoperability among these service management models is implemented by bridge protocol. The survey lays a foundation for next research for Internet service management.更多还原
