ADSP stands for AppleTalk Data Stream Protocol which is a Session layer protocol used to set up a session for exchanging data between various networking devices. It also provides the functionality of flow-control at the Transport layer. It guarantees sequential data delivery with flow control.
- It provides a symmetric, connection-oriented, and full-duplex communication between two sockets on the AppleTalk network.
- ADSP provides a strong interface to its clients, where clients have the permission to open connection, send data, receive data, and finally close connection using the remote end.
- It provides an attention message mechanism for the clients for their internal control.
- It provides a forward-reset mechanism which permits the clients to perform abort the delivery of outstanding bytes of data to the remote client.
- It also consists of a built-in flow control feature that guarantees that the data is sent by the application only if its remote partner has buffer capacity to accept the data.
- The data can be transmitted as a continuous stream or logically broken down into messages by the client.
- The connection could be rejected by this protocol.
- It includes both session and transport services.
- The half-open connections do not exist in ADSP i.e. it is full-duplex protocol.
- Sequential data delivery is guaranteed i.e. it is a reliable protocol.
- Duplicate data is not transmitted.
- It uses the Connection Control Block (CCB) to set up control information for synchronized communication among sockets and for error checking.
- It does not include authentication and encryption features.
- It does not support Transport Service Data Units (TSDUs) by default.
