Publish/subscribe gateway for voice communication

Currently, one trend in network research is to revise the architecture of the present Internet, from “Host-Centric Networking” to a new concept called “Information-Centric Networking (ICN)”. One of the ongoing projects in this field is PURSUIT, which uses the publish/subscribe paradigm as a basic communication model. In this paper we propose a novel design of a gateway which connects IP and PURSUIT publish/subscribe networks together, enabling their co-existence during an IP to pub/sub migration phase, for example. We focus on the gateway's mechanism to transparently convert IP-based end-to-end traffic to the publish/subscribe based, and vice versa, in order to support voice communication using Session Initiation Protocol (SIP). In addition, we describe our prototype implementation, evaluate the system's performance, and finally compare the call setup efficiency between IP and pub/sub networks.
