“…Elleuch and Houle proposed a large-scale peerbased MVoIP system in 2008. Their solution enables multihost media process support while the conference control and management are kept simplified and centralized around the administrator [4]. They build two different meshed networks to enable both voice audio distribution between participants and general conference control.…”

Achieving high-quality voice conference calls over the Internet is a difficult task. Heterogeneous mobile devices and network dynamics must be properly managed by multiparty VoIP systems to ensure a good quality of experience. In this paper, we propose a multiparty VoIP system based on SDN technology that uses both multicast distribution and dynamic stream adaptation to optimize the conference call quality for each participant. We define a tree construction algorithm that includes two modes: a minimum spanning tree mode and a shortest path tree mode. We have simulated conference calls with various parameters and results show that a trade-off can be achieved between path latency and bandwidth consumption when using multicasted streams with adaptive bitrates. Compared to a typical multiparty VoIP system, up to two-third bandwidth consumption reduction is possible with only a small increase of the average path latency. Our solution could be leveraged by other types of real-time applications such as online gaming.

“…In substitution to centralized and fully-coupled media flows, Application Layer Multicast (ALM) end-points based solution for large scale conference has been proposed [9][10][11]. These ALM solutions tend to produce self-organizing, efficient and self-improving overlay meshes that can be dynamically adapted to different network variations.…”

Several models and architectures are proposed to support multiparty communication over IP. Even if some of these solutions support large number of participants using a conference server, solutions that base their media distribution on peers are adapted to support only small conferencing groups. Deploying multimedia communication based on WebRTC API for more than browser-to-browser connection is not inherently supported and creates new challenge in terms of media stream distribution as well as membership and conferencing operation control overhead. Many conference models presented in this paper can support multi-party communication between endpoints over an IP networks. Otherwise, the use of WebRTC technology require direct P2P media negotiation between participants as well as signaling interaction with the Server to manage the conference. This paper introduces two specific conference models adapted to support WebRTC communication between browsers for both small scale and large scale conference. The proposed abstract protocols included in this work implements conference creation and browser joining/leaving and can be mapped using SIP/DSP primitives.

“…However, a minimum spanning tree is constructed based purely on delay constraints and coordinates in the physical network-thus, nodes may be far apart in the virtual space, but have to forward packets for which they have no interest in. Elleuch and Houle also use a tree-based media distribution network where mixer nodes and leaf nodes are distinguished [Elleuch and Houle 2008]. This setup allows resource-constrained devices to act only as receivers, while more powerful devices can act as senders, receivers and mixers.…”

“…As a result, these values need to be estimated and result in a sub-optimal solution. Note that similar to Elluech and Houle's work [Elleuch and Houle 2008], the tree is organized around delay between peers and not distance in the virtual world.…”

Multiparty voice communication, where multiple people can communicate in a group, is an important component of networked virtual environments (NVEs), especially in many types of online games. In this paper, we present a new peer-to-peer protocol that uses Gabriel graphs, a subgraph of Delaunay triangulations, to provide scalable multiparty voice communication. In addition, our protocol uses positional information so that voice data can be accurately modeled to listeners to increase the immersiveness of their experience. Our simulations show that the algorithms scale well even in densely populated areas, while prioritizing the sending of voice packets to the closest listeners of a speaker first, thus behaving as users expect.
