Abstract
To make service location protocol of IETF which is to be used in the wide area network to discover the location of desired service when computing resources are connected to the network, and to support simless connectivity between wired and wireless network in service viewpoint, to support the diversity trend of service agents in WIF, it needs to improve SLP, so as to add Liaison Agent and Forwarding Agent with FAAdvert message that is to communicate in between those entities. LA entity confirms the location of service located in wide area network, and FA transfers service information. The usage of existing messages such as SrvRqst, SrvRply, AttrRqst, AttrRply, DAAdvert, SrvReg, SrvAck, SrvDeReg is same as ever in wide area service network. The behaviors of improved protocol is modeled into petri-net and prove that it is free of deadlock and live-lock by execution of the model.
