帧中继网络的数量稳定地增长.今天,大多数帧中继接点用来连接广域上的局域网.作为多点线路的另一方案,帧中继已受到系统网络体系结构(SNA)用户的普遍欢迎.为了跟上帧中继的增长和网间连接日新月异的发展,近几年,测试和测量设备厂商一直把帧中继能力附加在传输测试仪和协议分析仪上.某些测试设备厂商把帧中继测试能力建立在单独的专用平台上.另一些厂商已从专用解决方案转向以PC机为基础的平台.这种PC机平台与接口卡,以及可以安装在PC机内的软件一起出售.此外,局域网与广域网网间分析仪也已问世.1994年,由德国Wandel＆Goltermann公司首创的局域网/广域网分析仪能同时监视、分析和仿真局域网和广域网接点.
The number of Frame Relay networks has steadily increased. Today, most Frame Relay contacts are used to connect to a wide area network. As an alternative to a multipoint line, Frame Relay has been used by System Network Architecture (SNA) users In order to keep up with the growth of Frame Relay and the rapid development of internetworking, test and measurement equipment vendors have been attaching frame relay capabilities to transmission testers and protocol analyzers in recent years. Some test equipment vendors Frame Relay testing capabilities are built on a dedicated dedicated platform, while others have moved from proprietary solutions to PC-based platforms that work with interface cards and software that can be installed in PCs In addition, LAN and WAN inter-network analyzers have also been introduced.In 1994, LAN / WAN analyzers pioneered by Wandel & Goltermann in Germany were able to monitor, analyze and simulate both LAN and WAN contacts simultaneously.
