摘要:
为解决传统集中式语音监听系统带宽占用大、存储效率低从而不易扩展的弊端,提出了采用云计算架构的语音督察系统.云架构语音督察系统采用分布式架构,通过逻辑统一、物理分离的方法将计算和存储等压力分布到区域服务器,设计网络调度算法将网络流量集中在区域内,避免核心网络的负载压力过大;通过调度算法对各服务器的压力进行调度,实现全系统的负载均衡和冗余备份,保障系统的稳定性和可靠性;结合云计算架构特点构建了10个音频服务以实现语音督察系统的实时监听、音频存储与备份、历史音频查询与回放及问题督察等功能.实验验证传统集中式语音监听系统随着规模扩展中心网络的吞吐也不断扩展,而云架构语音督察系统却增长很小,证明了云架构语音督察系统的易扩展性.
Abstract:
To solve the low scalability of centralized voice surveillance system caused by consuming more internet bandwidth and more storage, cloudy voice surveillance system was introduced. Distributed architecture was used in cloudy voice surveillance system to limit calculation and storage pressure in regional server by method of logical unity and physical separation and to avoid large load pressure in core network by design of network scheduling algorithm for concentrating network traffic locally. The scheduling algorithm for dispatching each server’s pressure to achieve load balancing and scheduling, redundancy backup, was implemented to guarantee system stability and reliability. Ten audio services compounding architecture features were constructed to realize real-time monitoring, audio storage and backup, audio history records query and playback, problem handling and other functions of voice monitoring system. Experimental tests show that the through put of central data network in traditional central voice monitoring system is expanding with the development of central voice monitoring system. However, the growth of the cloud architecture voice monitoring system is small. All these proved the latter’s high scalability.
