基于Tilera众核平台的流媒体流量发生系统的设计

Design of streaming media traffic generation system based on Tilera many-core platform

设计了一种基于Tilera众核平台高强度的流媒体流量发生系统架构,其主要包括:系统界面管理模块、服务承载模块和流媒体流量发生模块。系统以流媒体用户行为模型为基础,针对Tilera众核平台进行合理的任务并行的划分,进而完成系统整体框架的并行化设计。经实际测试验证,该系统模拟产生的流媒体流量在不同情景下具有网络吞吐率高、并发用户数多、流媒体流量更为真实的优点,可以对科研人员的网络设备性能测试、网络协议评估等提供更好的支持。

A new system architecture of streaming media traffic generator based on Tilera many- core platform is proposed, it in-cludes module about system interface of management, service loading module and traffic module about streaming media. This system takes advantage of the powerful parallel processing ability and efficient network throughput features of Tilera platform, combined with user behavior of streaming media and parallel technology on Multi- core. After a large number of tests, it proved that the system could generate enough streaming traffic and number of concurrent users under different scenarios, at the same time, the network traffic generated by this system is more real. And the system could provide better support for the study of scientific research per-sonnel about the testing of network equipment performance and evaluation of network protocols, etc.
