【摘要】 该文以协同设计技术为背景，针对网络拓扑结构，提出了广义树、广义图的概念以及树图嵌套、图树嵌套的方法。 用这种方法可推演出结构、性能优越的网络结构。 该文还探讨了利用通用协议TCP／IP实现这种方法的一些技术问题。更多还原

【Abstract】 ： With the background of Co－design technique，probing into network extension structure，this paper brings forward two key concepts：Extensive Tree，Extensive Graph；and two key methods：Nestification of Tree in Graph，Nestification of Graph in Tree.Using these Methods，we can deduce net structures which are superior in both aspects of construction and function.This article also discusses some technical problems about how to achieve these methods with universal protocol TCP／IP．更多还原
