International audienceReal-time communications are much more than only traditional voice services. They have become interactive, transversal and are expected to be integrated as a feature of other applications. More and more communications services are offered by web companies that have been taking advantage of Internet flat rate charges and mostly use best-effort capabilities. Simultaneously, many efforts are currently devoted to improve the quality of experience of clients using communication services. The paper analyses current implementations of managed VoIP and emerging WebRTC technology in order to assess the possibility of offering specialized media flow treatments to real-time web communications. It proposes two research approaches: "in-network" and "over-the-network" and several elements that could contribute to an overall solution allowing web communication services to benefit from specialized network services
International audienceThe omnipresence of real-time communication has significantly increased in recent years. Nevertheless it is treated as any best effort traffic, regardless its vulnerability to network conditions. WebRTC allows communication between browsers and uses application layer mechanisms to assure the quality (e.g. congestion control), but would benefit from network layer mechanisms. In this paper we evaluate specialized network treatment based on queuing management for uplink in wired access networks. We propose a test environment and later, based on application and network layer measurements, we assess the impact of proposed solutions on WebRTC quality. We prove that best effort is not enough to assure WebRTC communication in a presence of TCP flows and that network layer mechanisms can significantly improve the perceived quality of WebRTC communication

Nowadays, an in-app payment mechanism is offered in most existing mobile payment solutions. However, current solutions are not flexible and impose certain restrictions: users are limited to predefined payment options and merchants need to adapt their payment mechanisms to each payment provider they use. Ideally mobile payments should be as flexible as possible to be able to target various markets together with users' spending habits. Mozilla wants to promote an open approach in mobile payments by offering a flexible, easily accessible solution. This solution is analyzed, its shortcomings and possible improvements are discussed leading to an original proposal.
