Improved Non - Real - Time Communication in FDDI Networks withReal - Time

چکیده
The Fiber Distributed Data Interface (FDDI) is suitable for real-time communication because of the high speed and the performance guarantees it provides. However, these guarantees are achieved at the expense of non-real-time traac because the real-time messages are given higher priority over non-real-time messages, resulting in excessive delays for non-real-time messages. In this paper, we propose a scheme for reducing the response time of non-real-time messages while still providing the same quality of service to real-time messages. In the proposed approach, non-real-time messages are transmitted ahead of real-time messages unless it is absolutely necessary to transmit real-time messages rst in order to meet their deadlines. Simulation results show that a substantial reduction in the mean response time of non-real-time messages is achieved when using the proposed approach.

We report our ongoing research in real-time communication with FDDI-based reconngurable networks. The original FDDI architecture was enhanced in order to improve its fault-tolerance capability while a scheduling methodology, including message assignment , bandwidth allocation, and bandwidth management is developed to support real-time communication. As a result, message deadlines are guaranteed...

Token passing channel access mechanisms are used in several communication networks. An important class of token passing approaches are the so-called timed token protocols, which are able to manage both real-time traffic and non real-time traffic. Recently, a new token passing protocol, called Budget Sharing Token protocol (BuST), was proposed to improve the existing timed token approaches in te...
