Schedule policy based on data services plays a key role on the performance of the hsdpa . considering the priority and delay requirement of service, packet scheduler concentrates on the trade-off between the cell throughput and user fairness 基于數(shù)據(jù)業(yè)務(wù)的調(diào)度策略是hsdpa業(yè)務(wù)的主要保障機(jī)制,設(shè)備需要根據(jù)端到端業(yè)務(wù)質(zhì)量的要求,考慮業(yè)務(wù)的優(yōu)先級和時(shí)延要求的情況下兼顧公平性原則,盡量使小區(qū)的吞吐量最大化。
In packet switching network the essential assignment of packet scheduler is to determine the order and time slot of packets service and satisfy the qos requirement . the research work in this paper is implemented through computer simulations . the whole paper is organized as follows 在分組交換網(wǎng)絡(luò)里,當(dāng)有多個(gè)分組業(yè)務(wù)流等待接受服務(wù)時(shí),必須確定合理的服務(wù)規(guī)則,安排流的服務(wù)順序和服務(wù)時(shí)間,以滿足各個(gè)業(yè)務(wù)流的qos要求,這就是分組調(diào)度所要解決的基本問題。
We study statistical qos service and describe the admission framework of statistical qos service . we study the statistical performance of packet scheduler under e . e . b . model so as to support rapid admission of statistical qos . we design statistical traffic shapping controller that shapes arrival traffic processes on intermediate nodes 討論了網(wǎng)絡(luò)對統(tǒng)計(jì)性qos服務(wù)的支持,描述了統(tǒng)計(jì)性qos服務(wù)準(zhǔn)入控制的算法框架,分析了包調(diào)度器在e.b.b.通信模型下的轉(zhuǎn)發(fā)時(shí)延的確定性和統(tǒng)計(jì)性性能,使得統(tǒng)計(jì)性qos服務(wù)的快速準(zhǔn)入成為可能。
