摘要: 设计并实现一个互动电视业务边缘资源管理系统。采用轮播服务组信息的方式,实现终端的开机定位。对边缘IPQAM资源进行动态分配、回收,充分利用IPQAM资源。使用超时检测机制,保证资源的有效回收。运用数据缓存与限制最大等待请求队列长度的策略进行系统优化,将业务逻辑操作与数据库操作分离。性能分析结果表明,该系统经过数据缓存优化后,并发响应速率明显提升,响应时延降低。

Abstract: This paper designs and implements an edge resource management system based on data caching for interactive digital TV services. End system terminal such as set-top box achieves the correct positioning through carouseling service group information. By using dynamic resource management algorithm, the edge resource management system allocates and reclaims IPQAM resources. By using data caching and the max-waiting-length threshold strategy, it ensures high concurrent processing capability, and the use of overtime monitoring mechanism guarantees effective recycling of resources. Performance analysis results show that with data caching, the system significantly improves the concurrency and greatly reduces the average response latency.

Key words: resource management, resource allocation, data cache, digital television, interactive services
