基于局域网的会议电视通信平台设计

Design of Communication Platform for Conference TV Based on LAN

由于传统平台在实际应用中经常出现数据丢失、丢包率较高等问题,为此提出基于局域网的会议电视通信平台设计研究.会议电视通信平台整体架构采用IGG构架,由应用层、服务层、数据层、运行支撑层组成;采用线型拓扑结构局域网对平台会议电视通信方式进行设计;将UDP协议作为平台通信协议,并对UDP协议指令帧和应答帧格式进行设定,以此完成基于局域网的会议电视通信平台设计.经实验证明,此次设计平台丢包率在0.008%-0.025%,低于传统平台的丢包率.

Due to the data loss and high packet loss rate of traditional platform in practical application,this paper proposes the design and research of video conference communication platform based on LAN.The overall architecture of the video conference communication platform adopts the IgG framework,which is composed of application layer,service layer,data layer and operation support layer.The LAN of linear topology structure is used to design the communication mode of the platform conference television.UDP protocol is used as the platform communication protocol,and the format of command frame and response frame of UDP protocol is set to complete the video conference communication based on LAN Experimental results show that the packet loss rate of this design platform is between 0.008%~0.025%,which is lower than the traditional platform.
