transport layer
(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).
{OSI} documents: {ITU} Rec. X.214 (ISO 8072), ITU Rec. X.224
(ISO 8073).
