| Abstract: | Real-time performance in LTPB communication network is investigated under the effects of bandwidth allocation schemes. An optimal bandwidth allocation scheme (OLA) for LTPB network and an real-time performance analysis method based on WCAU(the worst available utilization) are proposed . Formal proof that OLA has better performance than any other schemes is given. Finally examples are given to demonstrate the correctness of the conclusion. |
