Components

Linux Data Link (ldl) Driver

The Linux Data Link product provides a Data Link Provider Interface (DLPI) for Linux network interfaces as well as providing a Linux networking interface for STREAMS drivers supporting the Data Link Provider Interface (DLPI).

STREAMS INET (strinet) Driver

The IP product provides a Internet Protocol (IP) multiplexing driver which provides Transport Provider Interface (TPI) to the native Linux NET4 IP implementation.

STREAMS SCTP (strsctp) Driver

The SCTP product provides a Stream Control Transmission Protocol (SCTP) STREAMS multiplexing driver which provides SCTP protocol modules. In addition, this product is responsible for a Linux Native implementation of SCTP and STREAMS access to the Linux Native implementation.

OpenSS7 has two Stream Control Transmission Protocol (SCTP) drivers: one for the STREAMS stack which is written as a STREAMS driver; another native to the Linux kernel. OpenSS7 provides an INET package for STREAMS which provides a STREAMS Transport Provider Interface (TPI) to our Linux native kernel (sockets) implementation, as well as providing an SCTP STREAMS driver which provides Transport Provider Interface (TPI) and Network Provider Interface (NPI) under STREAMS.

Linux SVR4.2 STREAMS

The STREAMS product provides a high-performance, production replacement for Linux STREAMS (LiS), called Linux Fast-STREAMS, or LfS, for short.

Linux 2.4/2.6 Kernel

OpenSS7 does not currently need any specific kernel projects other than STREAMS and the various drivers and modules.

Interfaces

XTI Library (libxnet)

The STREAMS X/Open Transport Interface (XTI) product provides an XNS 5.2 compliant XTI interface library, and a cooperating set of timod(4) and tirdwr(4) modules.

Socket System Driver (socksys) and Module (sockmod)

The STREAMS Socket System product provides an SVR 4.2 compliant socket system interface for Linux Fast-STREAMS.

Sockets Library (libsocket)

The STREAMS Sockets product provides an XNS 5.2, POSIX/SUSv3 compliant sockets interface to Streams supporting the Transport Provider Interface (TPI).

STREAMS DDI/DKI Compatibility (strcompat) Modules

The STREAMS compatibility modules product provides STREAMS DDI/DKI interface compatibility for most major UNIX STREAMS implementations, including AIX, HPUX, IRIX, LfS, LiS, MacOT, OSF/1, SVR 3.2, SVR 4.2, and UnixWare.
