QoS support for IEEE-1394 requests

IEEE-1394 is widely adopted in various commercial products for computing, communication, and entertainment. Although many services with Quality of Service (QoS) supports are now available in systems over IEEE-1394, little work is done for QoS-based resource allocation. In this paper, we aim at the design of a bandwidth reservation mechanism and its policy for isochronous requests, such as those from cameras. We then address the QoS support issue for asynchronous requests, such as those from disks, and then an analytic framework for probability-based QoS analysis. The capability of the proposed methodology and the analytic framework is evaluated by a series of experiments over a Linux-based system prototype.
