An Infrastructure of Network Services for Seamless Integration in Advanced Collaborative Computing Environments

Advanced collaborative computing environments are one of the most important tools for integrating high-performance computers and computations and for interacting with colleagues around the world. However, heterogeneous characteristics such as network transfer rates, computational abilities, and hierarchical systems make the seamless integration of distributed resources a challenge. In this paper, we argue that advanced collaborative computing environments need an infrastructure of network services to support distributed and quality guaranteed multimedia applications. Accordingly, we propose the design of network services for high-performance collaborative computing. We present a collaborative environment network service infrastructure (CENSI) to embed network services into various systems intelligently and elastically. We also discuss three management modules: a three-party matching module (resources, requests, and network services), a module for performance monitoring and evaluation of group communications, and a module for distribution topology analysis
