摘要:探讨了数字孪生网络南北向接口和孪生层内部接口应具备的不同特性,并给出了当前一些通用接口在数字孪生网络中的适用性建议。同时,针对数字孪生网络面临的多协议问题,提出在孪生网络层和物理网络层间引入南向接口协议适配功能,在孪生网络层和网络应用层间引入北向接口协议适配功能。借助南向和北向的接口协议适配功能,分别提出南北向多协议的识别、解析、转换方法,实现孪生层内部接口的多协议协同,降低构建数字孪生网络的协议处理的复杂度。

Abstract: The different characteristics of the north-south interface and the internal interface of the twin layer in the digital twin network and the applicability suggestions of some general interfaces for the digital twin network in the current network are given. At the same time, aiming at the multi-protocol problem of digital twin network, the southbound interface protocol adaptation between the twin network layer and physical network layer, and northbound interface protocol adaptation between the twin network layer and network application layer are introduced. Based on the protocol adaptation function of southbound and northbound interfaces, the identification, parsing, and transformation methods of southbound and northbound multi-protocol are proposed to realize the multi-protocol collaboration of interfaces in the twin layer and reduce the complexity of protocol processing in constructing digital twin network.   
Keywords: digital twin network; network twin; multi-protocol collaboration; closed-loop control
