摘要
数据交换设备可根据数据报文的优先级提供差别化服务。本文介绍了一种基于VLAN标签的优先级重标记方法,并在山东广电IP微波线路上应用此技术,经测试及实际运行后该技术可确保重要节目信号在信道劣化时的不间断传输,增强了安全播出技术保障能力。
Data exchange equipment can provide differentiated services according to the priority of data packets.This paper introduces a priority re-tagging method based on VLAN tag,and applies this technology on IP microwave line of Shandong Radio and Television.After testing and actual operation,this technology can ensure uninterrupted transmission of important program signals when the channel is deteriorated,and enhance technical guarantee ability of safe broadcasting.
