摘要

针对千兆无源光网络系统无法满足一些新服务的问题

如分辨率不断增长的互联网视频协议要求

文章提出了一种改进的GIANT动态带宽分配（DBA）算法。通过传输容器（T-CONT）的优先级划分带宽

将T-CONT1的带宽分配给每个分配标识

其主要目的是降低数据、视频和语音等服务的延迟。所提算法将这些服务表示为传输容器

用于动态地改进无源光网络系统的上行带宽分配和传输状态。仿真实验验证了所提算法的有效性

与不带DBA的方法和使用未修改的GIANT算法相比

所提算法可以显著降低超文本传输协议（HTTP）服务与"三合一"服务的延迟

将HTTP服务和视频点播服务的延迟分别降低了0.30和0.35 ms。

Abstract

The Gigabit Passive Optical Network（GPON） systems cannot meet some new service problems

such as increasing resolution requirements of video broadcasting in Internet Protocol Television（IPTV）. In order to solve these issues

an improved GIANT Dynamic Bandwidth Allocation（DBA） algorithm is proposed. By prioritizing the bandwidth of T-CONT

the bandwidth of T-CONT 1 is allocated to each Alloc-ID. Its main purpose is to reduce the delay of data

video

voice and other services. The proposed algorithm represents these services as transport containers

which are used to dynamically improve the uplink bandwidth allocation and transmission state of Passive Optical Network（PON） systems. The effectiveness of the proposed algorithm is verified by simulation results. Compared with the DBA-free method and the unmodified GIANT algorithm

the proposed algorithm can significantly reduce the latency of Hyper Text Transfer Protocol（HTTP） service and triple-play service. The latency of HTTP and Video on Demand（VoD） services are reduced by 0.30 and 0.35 ms

respectively.
