在远程控制领域中,网络化控制技术已经比较成熟,但在舰船通信装备控制网络中,需要具有串行和从属关系的多级链路的控制应用。利用初始会话协议(Session Initiation Protocol,SIP)可以方便地建立起多级链路,SIP协议自带的状态机组足以应付复杂的多级链路控制;同时在链路建立的情况下,SIP协议中的信息方法(INFO)可以方便地传输、交换私有控制信息和反馈信息,实现舰船通信装备的多级链路控制。

In the field of remote control,network control technology has been mature relatively,while in the control network of shipborne communication equipment,it still needs the control application of multilevel link with serial or master-slave relationship.The use of Session Initiation Protocol(SIP)facilitates the set-up of multilevel link,and the state unit of SIP protocol can fully deal with the control of complex multilevel link.At the same time,when link is set up,INFO method in SIP protocol can easily propagate and exchange private control and feedback information.
