摘要
随着彩铃、IVR等多媒体增值业务需求的增加,电信网络中媒体资源服务器的多媒体并发处理能力逐渐成为这些增值业务发展的主要制约瓶颈。该文在分析媒体资源服务器特性的基础上,提出一种基于异构多核微处理器架构的媒体资源服务器的解决方案,探讨媒体资源服务器在该多核架构下的设计及媒体处理的性能优化,并进行相关测试。仿真测试结果表明,该设计可以获得高于现有通用处理器平台下媒体资源服务器2倍～4倍的性能表现。
As the demand of multimedia value-added services becomes larger than ever before, the capacity of media resource server becomes the bottleneck of the development of these services. In this paper, a heterogeneous multi-core processor based media resource server solution is proposed based on the analysis of characteristics of media resource servers. The paper focuses on the architecture of the server and optimizing of media process under the heterogeneous multi-core architecture. Simulation test shows that the media resource server can get 2-4 times performance boost than previous solution.
