MTP3 Overview

Description: OpenSS7 SS7 Stack Overview.

This is the Signalling System No. 7 (SS7) Message Transfer Part (MTP) Level 3 (MTP3) component of the OpenSS7 SS7 stack. This component implements the MTP Level 3 functions in a STREAMS multiplexing driver.

The MTP3 STREAMS driver provides three user-level interfaces: the Message Transfer Part Interface (MTPI), the Network Provider Interface (NPI) and the Transport Provider Interface (TPI).

The MTP3 STREAMS driver supports I_LINK and I_PLINK of Signalling Link Interface (SLI) streams providing SS7 MTP Level 2 signalling links under the multiplexing driver.
