(XOT) 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.

Figure 66 XOT typical application diagram

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
