With evolution of Internet, next generation Internet primarily is a network-service-driven. In the future, Especially, Telecommunication network, computer network and wireless mobile network will be merged into an all-IP network,
services provided by this large scale network will increase by exponent. This will result in some critical problems--how to effectively manage these services provided by such network to make service users obtain their QoSguaranteed-service at anytime and anywhere. Study shows that the interaction between service providers and service
users, in practice, is a service level agreement (SLA) process. Therefore, SLA acts as quite importance, In this paper, a
kind of perspective of using service location protocol (SLP) to implement SLA is proposed based on fully researching
of SLP. The main idea is as follow: information of SLA object can be bound to user agents' (UA) request messages.
Comparison with conventional method, it not only cuts down the agreement numbers between service providers and
service users, but also saves network bandwidth and guarantees QoS.
