So , bandwidth allocation scheme is very necessary for epon system due to requests of higher uplink bandwidth utilization and qos for different services 为了提高上行带宽的利用率,保证不同业务的qos ,本文将对上行带宽分配算法做详细讨论。
However , the combination of atm will serve to realize on - demand bandwidth allocation according to the required qos and the actual traffic condition 利用atm技术来传送这些业务时,就能够根据所需要的服务质量( qos )级别和需要传输的实际业务量来按需分配带宽。
Weighted fair queuing ( wfq ) , on the other hand , allows allocation of bandwidth on a variable basis , so not all flows have to have the same bandwidth allocation 另一方面,加权公平排队( wfq )允许在可变的基础上分配带宽,因而不是所有的信息流都必须有相同的带宽分配。
It is the key of realizing uplink access in epon that how to design a fair , high - performance and supporting different service qos dynamic bandwidth allocation algorithm 如何设计一种公平、高效、支持不同业务qos的上行接入带宽分配算法是无源光网络实现综合接入的关键。
Based on analyzing the upstream channel ' s description in the docsis protocol , the author profoundly explored the upstream channel ' s bandwidth allocation algorithm in the hfc network 在对docsis协议中上行信道描述部分的分析基础上,对上行信道的带宽分配算法进行了深入的研究。
Reservation based dynamic bandwidth allocation scheme still adopts the concept of uniform spacing , and the access of request slot adapts to loading situation , which improves the non - real time services 动态带宽分配算法自适应于系统的负载状况,最大限度改善了非实时业务的性能。
Instead of prioritizing bandwidth allocation , users can inexpensively overprovision bandwidth when they need to support delay - sensitive traffic such as voice and video 当用户需要支持对延迟敏感的流量,如声音和视频图形时,他们可以廉价地获得很大的带宽,而不用对带宽进行优先等级分配。
Instead of prioritizing bandwidth allocation , users can inexpensively overprovision band - width when they need to support delay - sensitive traffic such as voice and video 当用户需要支持对延迟敏感的流量,如声音和视频图象时,他们可以廉价地获得很大的带宽,而不用对带宽进行优先等级分配。
The dissertation proposes two fair bandwidth allocation algorithms : mblue ( modified blue ) and ufqr ( user fair queuing with reservation ) . 1 . mblue aims at average fairness 针对数据传输过程中带宽分配存在的问题,以及目前的研究现状,提出了两种公平的带宽分配策略及算法,其主要内容如下: 1
The set - up of prediction model and its application in real network traffic are very important in the researches of bandwidth allocation , discarding methods , and loss ratio reducing 建立预测模型及根据模型进行预测,对于网络带宽资源的分配、改进网络中缓冲区的丢弃算法、减小丢失率都具有十分重要的意义。
Bandwidth allocation is the process of assigning radio frequencies to different applications. The radio spectrum is a finite resource creating the need for an effective allocation process.
