同一物理网段上多逻辑网的并存

Coexistence of Multi-logic-Network on The Same Physical Network

基于网络互连和应用发展要求，讨论了现有网络互连方法、局域网络协议及拓扑结构以及ＴＣＰ／ＩＰ在此基础上，提出逻辑网络的定义以及多种逻辑网络共存于同一物理网段的模型，并给出一实例。

On the basis of the demand of network interconnection application and development, this paper discusses the current method of network interconnection, the protocol of LAN, the topological structure and TCP/IP Based on the above discuss, the authors give out the definition of Logic Network and the model of Multi-Logic-Network coexistence on the same physical network The end of this paper is an example and the discussion of the model′s application
