Abstract:
A national large-scale IPTV system needs to consider how to make its performance optimized when providing user with various multi-media services. This paper describes the architecture of IPTV system and Web cache methods. It finds the bottleneck of EPG performance after analyzing test data, and designs a cache architecture named EPG_Cache to fit IPTV system. EPG_Cache can improve EPG performance by caching part of valuable data.

摘要: 电信级IPTV系统向用户提供丰富的节目的同时也要考虑提高系统自身的性能。该文描述了IPTV系统架构与现有的 Web Cache 技术,通过对测试数据的分析找到影响EPG性能的瓶颈。分析了IPTV系统的特点,提出了一种适合IPTV 系统的Web cache 架构 EPG_Cache,EPG_Cache通过提供缓存部分数据的方法提高EPG的响应速度。
