Isochronous Resource Reservation for the Deterministic Delay Guaranteed Collaboration

With increasing processor speeds and convergence on wired-wireless networks, the potential for computing complex behavior in real-time collaboration has greatly improved. In recent years, distributed virtual environments have become a major trend and application fields of collaboration have been diffused into machine-to-machine services. Collaboration requires communication channels among resources and coordination functions for the integration and harmonious adjustment of the individual work effort towards the accomplishment of a goal. For realizing the advanced collaborative environments, highly interactive communication will be indispensable. New features from Ethernet technology to meet delay and jitter requirements for time-constrained collaboration will be required. In this paper, to obtain the deterministic latency transport for supporting the time- constrained collaboration, Ethernet frame forwarding with the isochronous resource reservation is proposed. We define the isochronous forwarding window which is the time duration and virtually identified on point-to-point links, and propose the resource reservation in terms of isochronous forwarding window with the admission algorithm based on probabilistic admitted level of quality for the collaboration communication channel.
