Protocol Portability

Figure 1–6 shows how an X.25 protocol module can work with different drivers on different machines by using compatible service interfaces. The X.25 protocol module interfaces are Connection Oriented Network Service (CONS) and Link Access Protocol – Balanced (LAPB).

Figure 1–6 Protocol Module Portability

Diagram demonstrates that the same protocol module can
be used by different drivers on different machines.
