This draft describes a Kademlia-based protocol for Resource Lookup in P2PSIP. The proposed protocol is based on dSIP, a SIP-based protocol proposed by other authors as generic framework for a distributed SIP Location Service. Although the dSIP authors have obsoleted the draft by a newer approach based on a binary protocol named RELOAD, we are still considering this SIP-based approach, due to implementation simplicity, possibility of reuse of already available SIP stack implementations, easy integration into existing UAs, minimization of the number of required protocols for a P2P UA, and widespread support for (and relative maturity of) the SIP standard.
