如何解决异构计算机网络的互连问题至关重要，网络实时通信也是当前计算机网络应用的热点。本文针对这两方面的问题，提出了异构网的同构化思想，讨论了网络实时通信的实现方法，并给出了异构网中解决进程实时通信问题的模型和方案。 How to solve the interconnection problem of heterogeneous computer networks is very important. Real-time network communication is also a hot spot in the current computer network applications. In view of these two problems, this paper puts forward the idea of ​​isomorphism of heterogeneous networks, discusses the method of realizing real-time communication in networks, and presents the models and schemes to solve the real-time communication problems in heterogeneous networks.
