綜合業(yè)務(wù)衛(wèi)星廣播網(wǎng)帶寬分配策略研究

本文在對綜合業(yè)務(wù)衛(wèi)星廣播網(wǎng)所承載業(yè)務(wù)進行了分類并分析了各類業(yè)務(wù)QoS 需求的
基礎(chǔ)上，提出了一種基于優(yōu)先級和自適應(yīng)最小回轉(zhuǎn)周期輪轉(zhuǎn)調(diào)度的適合于綜合業(yè)務(wù)衛(wèi)星廣播網(wǎng)的帶寬分配策略。仿真結(jié)果表明，該帶寬分配策略能夠滿足綜合業(yè)務(wù)衛(wèi)星廣播網(wǎng)各類業(yè)務(wù)的QoS 需求。

Abstract：In this paper, we propose a bandwidth allocation scheme that is applicable to the
integrated service satellite broadcast network. Based on the study of service categorization and their QoS requirement, the scheme is a new hybrid one which combines priority queuing and adaptive minimized cycle round robin. Simulation results show that the proposed scheme can meet the QoS requirement of services in the integrated service satellite broadcast network.
Key words：satellite broadcast network; bandwidth allocation; QoS
