局域网经分组交换网的互连技术

Interconnection technique of LAN through packet switching networks

研究了Ｋ－ＮＥＴ局域网经Ｘ．２５公用分组交换网实现互连的有关技术。在将局域网与分组交换网的特性进行比较的基础上，给出了一种“逐网”“站级”的网际互连结构，并提出了互连中若干关键问题的解决办法：使用信用量分配技术解决网际信息流控制、将局域网的寻址扩展成多级寻址方式以解决网际寻址问题和在网关中实现分组的分割与重装等。

An investigation in the K--NET interconnection technique through the X. 25 PSPDN (packet switching public data network) is conducted. Based on the comparison between the characteristics of LAN and PSPDN, a kind of respective--net and workshop--level internetwork interconnection structure is given.Some of key problems about interconnection are discussed: a flow control technique for internetworking based on credit distribution, a multi-level addressing scheme of LAN for internetwork addressing, the approach of pack;tsegmentation and reassembling.
