TTCP is a benchmarking tool for determining TCP and UDP performance 
between 2 systems.

The program was created at the US Army Ballistics Research Lab (BRL)
and is in the public domain. Feel free to distribute this program
but please do leave the credit notices in the source and man page intact.

Contents of the directories:

SRC/ttcp.c		Source that runs on IRIX 3.3.x and 4.0.x systems
		and BSD-based systems.  This version also uses getopt(3) 
		and has 2 new options: -f and -T.

SRC/ttcp.c-brl	Original source from BRL.

DOCS/ttcp.1		Manual page (describes ttcp.c options, which are a 
		superset of the other version).

SRC/ttcpATM.c   NCSU mods for ATM measurements (needs to be checked)
 

SRC/ttcpATMS.c  NCSU mods for ATM measurements (using SONET) - needs to be
                checked.

OS2/TTCPOS2.EXE IBM compiled OS2 version

W95-98-NT/      ttcpw - NCSU port of ttcp to Windows95/98 and NT 
                (includes a Word-based - DOC - and text-based Manual)

UNIX/AIX        NCSU compiled AIX 3.2.5 versions (will run on AIX 4.1 and 
                4.2)

UNIX/SunOS5. 4  NCSU compiled Sun OS 5.4 version

UNIX/Ultrix4.3  NCSU compiled Dec Ultrix 4.3 version

Java            NCSU re-write of ttcp for Java (alpha version)

How to get TCP performance numbers:

	receiver				sender

host1%  ttcp -r -s			host2% ttcp -t -s host1

-n and -l options change the number and size of the buffers.

Do ttcpxxx -h for more help on options.
