(Or "host-host layer") The middle layer in the
OSI seven layer model. The transport layer determines how
to use the network layer to provide a virtual error-free,
point to point connection so that host A can send messages to
host B and they will arrive un-corrupted and in the correct
order. It establishes and dissolves connections between
hosts. It is used by the session layer.
An example transport layer protocol is {Transmission Control
Protocol} (TCP).

TLI
Transport Level Interface
(TLI, or "Transport Level
Interface") A protocol-independent interface for accessing
network facilities, modelled after the ISO transport layer
(level 4), that first appeared in Unix SVR3.
TLI is defined by SVID as transport mechanism for networking
interfaces, in preference to sockets, which are biased
toward IP and friends. A disavantage is that a process
cannot use read/write directly, but has to use backends using
stdin and stdout to communicate with the network
connection. TLI is implemented in SVR4 using the STREAMS
interface. It adds no new system calls, just a library,
libnsl_s.a. The major functions are t_open, t_bind,
t_connect, t_listen, t_accept, t_snd, t_rcv, read, write.
According to the Solaris t_open man page, XTI (X/OPEN
Transport Interface) evolved from TLI, and supports the TLI
API for compatibility, with some variations on semantics.
