.SH NAME
isoc \- minimal ISODE client for testing
.SH SYNOPSIS
.in +.5i
.ti -.5i
.B isoc
host provider entity
.in -.5i
.SH DESCRIPTION
The \fIisoc\fR program requests a few minimal ISODE services
and is useful primarily for debugging purposes.
Currently,
several entities can be requested, depending on the provider selected.
The echo entities will verify that the data they send is received correctly.
The \fIisode/\fR entities use association control (when applicable)
in order to test out these newer facilities.
.PP
Further,
to measure raw TCP performance, the \fIsink\fR entity can be requested of
the \fIraw\fR provider.
This option depends on the target system already having a TCP sink server in
place.
Berkeley UNIX sites usually have such a server.

Finally,
on those hosts with sub\-second timing facilities,
by redirecting \fIisoc\fR's standard input to a file,
raw performance at a given layer can be measured.
