遁信工程学院所研究的分组交换的话音数据综合业务局域网(ISLN),已获得阶段性研究成果。1987年4月14日,参加此项研究工作的四名硕士研究生进行了论文答辩,并在答辩前进行了现场表演。 这个实验的ISLN取名为NICENET(Nanjing Institute of Communications Engineering NET),是令牌总线型结构。这种结构具有总线型局域网接入站点比较灵活的优点,同时也因令牌循环周期具有确定的上限值因而非常适合于 Silence Engineering Institute studied the packet-switched voice data Integrated Services LAN (ISLN), has been the stage of research results. On April 14, 1987, four master students participating in the research conducted a thesis defense and conducted a live performance before the defense. The experimental ISLN named NICENET (Nanjing Institute of Communications Engineering NET), is a token bus architecture. This architecture has the advantage of a more flexible LAN-based access site and also has a well-defined upper limit for the token cycle time
