Abstract

This paper proposes PhoneNet, an application framework to support direct group communication among phones without relay nodes. PhoneNet presents the familiar abstraction of a multi-user chat service to application writers. It performs two main functions: inviting participants to the chat room and routing data between participants directly without going through any intermediaries. Made possible by a generic chat room service embedded in the network itself, all application-specific code in PhoneNet applications runs on the phones themselves. Unlike the conventional server-client model, this design does not require scalable central servers that can handle all simultaneous interactions. As a first step, we have created a prototype of PhoneNet that works within an administrative domain. The multicast functionality among phones is implemented on top of a software-defined network (SDN). We have developed two applications using PhoneNet: teleconferencing and photo-sharing. Our experience suggests that it is easy to develop PhoneNet applications and PhoneNet appears to be effective in reducing network traffic.
