Tampere University of Technology This document specifies extensions to the Service Location Protocol verson 2 (SLPv2) which allow applications residing in Mobile IPv6 nodes to interact with SLPv2 agents in fixed networks. Each mobile node contains a Visiting Agent which communicates with Access Agents residing in fixed networks. In networks already deployed with SLPv2- based service infrastructure, this allows applications in visiting mobile nodes to use SLPv2 and provide site-local services without needing prior knowledge or static configuration of the networks they visit. By monitoring changes in Access Agent Advertisements, Visiting Agents can decide if the mobile node has moved to a new network, and if it is necessary to rediscover and reregister site- local services. This document extends SLPv2 and the SLP API with new message types, error codes and function calls. Both C and Java API bindings are provided.
