Due to its particular mixed topology of star and branch as well as its asymmetric upstream and downstream , the upstream channel ' s bandwidth allocation algorithm in hfc network has been a research hotspot domestic and abroad 由于hfc网络特有的星型与树枝型相混合的拓扑结构以及它的上下行非对称特性,使得hfc网络中上行带宽分配算法的研究成为了国际国内研究的热点。
To effectively and fairly allocate bandwidths between end users and ensure quality of service ( qos ) requirement , we propose a new fixed cycle polling dynamic bandwidth allocation algorithm 在设计动态带宽分配算法的时候,考虑到网络流量的特性,并满足提高系统的带宽利用率、保证公平性和qos ( qualityofservice )要求的目的,本文提出了一种固定轮询周期的保证qos的动态带宽分配算法。
Some common satellite resource allocation algorithms are analyzed in this paper , especially the wrr ( weighted round robin ) algorithm based on the flux estimate which can guarantee the qos of vbr ( variable bit rate ) 本论文首先分析了当前国内外一些常用的卫星资源调度算法,特别是基于流量估计的wrr ( weightedroundrobin )调度算法,它能够对vbr ( variablebitrate )业务进行很好的支持。

The paper also analyzed the request access delay ( rad ) when using the bandwidth allocation algorithm , and found that the number of allocated contention slots has little effect on the rad , however the rad connected with the length of upstream time segment being depicted 论文还分析了在该带宽分配算法影响下的请求分组访问延迟,发现请求分组访问延迟受竞争时隙数的影响不大,而是与map帧所描述的上行时间段的长短有关。
Then a new fixed cycle polling dynamic bandwidth allocation algorithm is proposed to support qos and improve bandwidth utilization in epon . the proposed algorithm consists of two parts : one is scheduling between olt and onus , and the other is scheduling between priority queues in onu 此算法将带宽分配过程分为两部分,首先是onu之间的调度,即olt给每个onu分配带宽;其次是onu内部的调度,即onu将带宽分配给各个优先级队列。
Simulation results showed that the new method can improve the system throughput , obtain higher transmit power utilization and decrease the number of invalid sub - channels without additional complexity when compared with the conventional power allocation algorithm 仿真结果表明,在准静态平坦衰落信道下,与传统算法(如注水算法)相比,新算法能进一步改善系统的吞吐量,提高发射功率的使用效率,减少不可用子信道个数,且无附加复杂度。
