NAME


ibtl - Solaris InfiniBand Transport Layer

DESCRIPTION


InfiniBand (IB) is an I/O technology based on switched fabrics. The
Solaris InfiniBand Transport Layer (IBTL) is a Solaris kernel misc module
and adheres to the IB Architecture Version 1.1 specification and provides
a transport layer abstraction to IB client drivers.


IBTL implements the programming interfaces for the Solaris InfiniBand
Transport Framework (IBTF), consisting of the IB Channel Interface (CI)
and the IB Transport Interface (TI).


The CI consists of Host Channel Adapters (HCAs) and HCA drivers. A host
is attached to the IB fabric through the CI layer. The Solaris InfiniBand
CI is Sun's API rendering of the InfiniBand Architecture (IBTA) "verbs"
specification.


The Solaris InfiniBand TI is the kernel service driver interface into the
Solaris InfiniBand Transport Framework. It provides transport and
communications setup programming interfaces for Unreliable Datagram (UD)
and Reliable Connected (RC) transport types only.
