Abstract

Abstract:

A media resource pool of multi-tenant cloud-based resource scheduling, load balancing implementation techniques and processes were proposed. Cloud media in the IMS service platform application solutions, cloud technology, media resources test situation were introduced, and cloud media business model was presented. In order to promote cloud media server hardware and software for the local manufacturers and related industry chain development provides a new idea.

Key words: cloud computing, media server, cloud based service platform, load balancing

类型	组网要求	备注
物理服务器与存储设备间的通信网络	光纤链接双链路冗余设计	为了避免物理服务器与存储间的通信线路出故障而导致所有虚拟媒体服务器应用停机，方案采用双链路冗余机制，即每台物理服务器与存储间都有两条独立的链路
物理服务器与物理服务器间的通信网络	1 000 MB以太网连接	部署独立的物理服务器间的交换网络，且该网络只用于各虚拟软件服务器之间的数据传输。采用双链路冗余机制

路数	云媒体虚拟机 CPU 占用	云媒体物理宿主机 CPU占用	云媒体虚拟机内存（MB）	云媒体虚拟机内存（MB）	呼叫成功率
100线	5.3%	0.0%	169	646	100%
300线	16.6%	1.0%	241	979	100%
500线	28.8%	1.0%	315	1 408	100%
1 000线	51.2%	8.3%	500	2 511	100%
注：本表CPU占用均指多CPU加权平均值。由于虚拟机为多核并发处理，单个CPU占用超过100%为正常现象，全局CPU占用进行加权平均计算
