Abstract:
This document describes an idea "Sharp Close" that eliminates or
minimizes TIME-WAIT state of TCP connections.
In the current TCP specification ([RFC0793]), there are some
inappropriate or not up to date functions. Here we focus and
discuss on TCP TIME-WAIT state function.
TIME-WAIT is the last state of TCP connection of Active Close side
node. After TCP connections are effectively closed, they move to
TIME-WAIT state. After TIME-WAIT state is finished, resources of
connections are released. This means that even if connections are
effectively finished, resources of connections are NOT released.
The TIME-WAIT state prevents from releasing them.
From the viewpoints of current high-speed and high-multiplicity
communication styles, it is thought that TIME-WAIT state is one of
evil functions.
In order to provide efficient communication that matches current
styles, an idea "Sharp Close" that eliminates or minimizes TIME-
WAIT state of TCP connections is proposed.
