Transport Service Access Point

Show me everything on The OSI Model

- In networking, the Transport Service Access Point (TSAP) is part of the Open Systems Interconnection (OSI) IP addressing scheme. It identifies the Network Service Access Point (NSAP) between the session layer and the network layer. The NASP is the part of a network address that identifies which application on the host is sending or receiving a packet.
