Introduction to XOT Protocol

XOT (X.25 Over TCP) is a protocol that is supported by TCP, and implements the
connection of two X.25 networks through IP network. The practical application
environment is shown in the following figure.

Since the application of IP network is broader and broader, the practical
applications of supporting X.25 data through IP net and connecting X.25
networks are becoming more and more. The conventional X.25 protocol is the
third layer of the OSI seven-layer model, i.e., the network layer, for which the LAPB
