iMSC 级联会议调度的讨论与实现 摘要由于网络的不断普与与应用，视频会议越来越广泛地应用于各个领域，视讯市场也在不断的进展壮大。目前，单个 MCU(Multipoint Control Unit)所能承受的会议容量已经不能满足特定环境下的需求，而不同会议存在于不同 MCU 时，我们又很难进行统一管理。因此，MCU 需要高效灵活的平台进行统一管理和调度，当单个 MCU 不能满足要求的时候，我们需要调度多个 MCU 进行级联，以实现会议的扩容。基于此，本文主要结合某公司开发的 iMOS(IP Multimedia Open System)平台，针对 MCU 间的互控级联进行进一步的讨论和分析，实现基于iMSC(Intelligent Multimedia Service Center)平台下对 MCU 互控级联进行统一管理和调度。本文从会议创建、会议控制和会议备份分析其流程实现，还考虑从原 MCU 稳定性出发，分析比较重要的几个策略。根据级联会议的特性，分析测试的测试策略与测试方案，以保障产品在开发完成时的质量。关键词： 视频会议，终端，多媒体控制单元，互控级联AbstractAs the growing popularity of the network and applications, video conferencing is becoming more widely used in various fields, the video market has continued to grow and develop. At present, the meeting can bear a single MCU(Multipoint Control Unit) capacity can not meet the needs of specific environments, and different meetings exist in different MCU, we are difficult to unified management. Thus, MCU need flexible and efficient platform for unified management and scheduling, when a single MCU can not meet the requirements, we need to schedule more than one MCU cascaded to achieve the meeting of the expansion. Based on this, this paper developed iMOS (Integrate Multimedia Open System) with a platform for interaction between the control cascade MCU for further research and analysis, platform-based iMSC (IntelligentMultimediaServiceCenter) cascade of mutual control of the MCU for unified management and scheduling. This created from the meeting, conference and meeting control...
