Application Layer Traffic Engineering for Multipoint Communication System

Abstract

Recent advancement of network systems enables various kinds of remote communication. In this paper, we focus on person-to-person multipoint communication. When we use multipoint communication systems, it's preferable to make maximum use of the available network resources to obtain the maximum communication quality. However, current systems are not possible to utilize the network resources effectively. In this paper, we propose a framework to describe a multipoint communication policy which enables application layer engineering for multipoint communication systems. By using our framework, one can easily control the multipoint communication like a traffic engineering over the broadband networks. To exemplify the effectiveness of the framework, we utilize SAMTK-3D which is a multipoint communication system in a three-dimensional virtual space. By using SAMTK-3D, we can reproduce an event held on a real space in a virtual space and enable a remote participation such that the mutual communication between a real space and a virtual space is possible. We also implement a policy management client which can visualize of the communication and control the multipoint communication policy.
