摘要:

随着国家大力推进三网融合,手持终端设备可以通过3G网络方便地浏览互联网上丰富的视频信息,但视频格式的多样化给用户浏览带来了诸多不便。通过对Linux虚拟服务器(LVS)调度算法的研究与分析,提出了一种改进的动态负载均衡算法ADLBA,并通过实验验证了该算法的可行性和有效性。

关键词: 负载均衡, 任务调度, LVS, 视频转码

Abstract:

With the rapid development of the triple play, mobile devices can access various video information on Internet by using 3G networks. However, it is not convenient for users that there are various kinds of video formats. An advanced task scheduling algorithm supporting dynamic loading balance (ADLBA) is  proposed based on the research and analysis of Linux Virtual Server (LVS). We implement it to prove its feasibility and practicality.
