STREAMS-based Transport Provider Interface

STREAMS-based Transport Provider Interface

This chapter describes the STREAMS-based Transport Provider Interface (TPI). TPI is a service interface that maps to strategic levels of the Open Systems Interconnection (OSI) Reference Model. TPI supports the services of the Transport Layer for connection-mode and connectionless-mode services. One advantage to using TPI is its ability to hide implementation details of a particular service from the consumer of the service. This enables system programmers to develop software independent of the particular protocol that provides a specific service. This chapter focuses on TPI as it is defined within the STREAMS environment.
