# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to ‘$srcdir/foo’. In other projects, it is set to
# ‘$srcdir’, ‘$srcdir/..’, or ‘$srcdir/../..’.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is ‘.’, but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir=’\$(top_srcdir)/’`expr “$ac_aux_dir” : “$srcdir//*$.*$”`
# and then we would define $MISSING as
# MISSING=”\${SHELL} $am_aux_dir/missing”
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this “fixed” $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

NEWUDPL

NAME
newudpl – Network Emulator With UDP Link

SYNOPSIS

DESCRIPTION
This is a tool to create various condition of packet switching behavior
artificially for UDP packets.

The emulator receives UDP packets on a designated port and then delays
them, drops some randomly, corrupts the content, swaps the order of
sending and emulates a finite-bandwidth link by queuing packets. It should
be useful to examine an efficiency of network protocols or codecs.

INSTALLATION
Source codes are available from:
http://www.columbia.edu/~at541/src

To build, unpack the tar file, then type:

./configure
make

I have only tested on SunOS 5.7, 5.8 system and Linux but it should
compile on other Posix-compliant platforms.

OPTIONS
-v
-vv
Verbose output
With a single -v,
the information of dropping packets by congestion and creating
random packet loss/bit error/out of order will be displayed;
with a second one, receiving and sending packets will also be shown.

-p receiving port : sending port

Specifies the binding ip-port for receiving and sending UDP packets.
Otherwise, default values will be used.

Available range: 1024 – 65535 or 0x400 – 0xFFFF
Default: receiving 41192, sending 41193

-s emulating link speed

Specifies a finite-bandwidth. The speed of Transferring UDP packets
will not exceed this speed. Unit is in kb/s.

Available range: 1 – 50000(MAX_KBPS)
Default: 1000

-e Ethernet speed

Specifies a Ethernet speed on the machine. It is used to calculate a
tranmission delay, which makes difference especially when the emulating
link speed is slow.

Available range: 1 for 10M, 2 for 100M, 3 for Gigabit Ethernet
Default: 10M(b/s)

-d delay

Specifies delay time. All the packets will have minimum delay. The
deley for each packet could be varies, depenging on the link speed.
For example, -d2 is 2 (sec) and -d1.345678 is 1.345678 (sec).

Available range: 0 – 10(MAX_DELAYSEC)
Default: 0

-q queue-buffer size

Specifies the size of queueing buffer for receiving packets. If you
large this number, less likly to have packet loss by congestion for the
same link speed.

Available range: 1 – 16384 or 0x1 – 0x4000(MAX_QBUFSIZE)
Default: 8192

-i source host [[ : | / ] port | * ]

Specifies the source host for receiving packets. If the emulater
receives a packet from a different host then the packet will be
rejected. The host name could be either IP number with dotted-decimal
notation (e.g., 128.59.16.8) or the host name (e.g., cs.columbia.edu).
If the port is not sepcified then it will accept only packets from the
the port 41191, default values, with corrsponding source host, but you
could rule out this checking by using ‘*’.

Default: host – localhost, port 41191
Example,
-i dynamo.cs.columbia.edu/32768
-i dynamo.cs.columbia.edu/0x8000
-> accepts packets only from dynamo.cs.columbia.edu/32768
-i diamond.cs.columbia.edu
-> accepts packets only from diamond.cs.columbia.edu/41191
-i 128.59.16.7:*
-> accepts packets any port from disco.cs.columbia.edu(128.59.16.7)

-o destination host [[ : | / ] port ]

Specifies a destination host for outgoing packets.

Default: host – localhost, port 41194

-B bit error rate

Specifies a rate of genarating bit errors for outgoing packets.
The rate is in 1/100000(BITERRDENOM).

Available range: 1 – 99999(BITERRDENOM – 1)
Default: 0

-L random packet loss rate

Specifies a rate of genarating random packet loss for outgoing packets.
The rate is in percentage.

Available range: 1 – 99
Default: 0

-C conditional Gilbert packet loss rate

Specifies a rate of conditional Gilbert packet loss

Available range: 0.0 – 1.0
Default: 0.0

-U average overall Gilbert packet loss

Specifies an average rate of unconditional overall Gilbert packet loss

Available range: 0.0 – 1.0
Default: 0.0

-O out of order rate

Specifies a rate of randomizing oreder of packets. The distination host
will receive some packets in out of order in certain rate.
The rate is in percentage.

Available range: 1 – 99
Default: 0

USAGE
To create condition under following parameters,

from: dynamo.cs.columbia.edu(128.59.16.4)/41191
to: disco.cs.columbia.edu(128.59.16.7)/41194
link speed : 50(kb/s)
delay : 2.004000(sec)
no packet errors

type,

newudpl -idynamo.cs.columbia.edu -odisco.cs.columbia.edu -s50 -d2.004

For,
verbose mode
from: any port of dynamo.cs.columbia.edu(128.59.16.4)
to: disco.cs.columbia.edu(128.59.16.7)/32768
with error rate
random packet loss: 7(1/100 per packet)
bit error : 5(1/100000 per bit)
out of order : 9(1/100 per packet)

newudpl -idynamo.cs.columbia.edu/* -odisco.cs.columbia.edu:0x8000 -v -L7
-B5 -O9

To stop the emulator,
1) press ctr-c
2) type any ‘q’ ‘quit’ ‘stop’ ‘exit’ from the console

ACKNOWLEDGEMENTS
For genarating a random variable corresponding to binomial distribution ,
I used the bnldev() function from
William H. Press, Brian P. Flannery, Saul A. Teukolsky, William T.
Vetterling, ‘Numerical Recipes in C’ The Press Syndicate of the University
of Cambridge, 1992.

This emulator was developed under supervising by,
Wenyu Jiang http://www.cs.columbia.edu/~wenyu/

## why we pick this rather obscure method:
## – Don’t want to use -MD because we’d like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## – The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the ‘gcc’ depmode.
## – Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the “deleted header file” problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn’t do
## this for us directly.
## Some versions of gcc put a space before the ‘:’. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can’t process this invocation

NEWUDPL

NAME
newudpl – Network Emulator With UDP Link

SYNOPSIS

newudpl [-[v|vv]] [-p [recv_port]:[send_port]]

[-i sorce_host[[:|/][port|*]]] [-o dest_host[[:|/]port]]

[-s link_speed] [-d delay] [-e Ethernet_speed] [-q queue_buf_size]

[-[B|L|C|U|O] error_rate]

DESCRIPTION
This is a tool to create various condition of packet switching
behavior artificially for UDP packets.

The emulator receives UDP packets on a designated port and then delays
them, drops some randomly, corrupts the content, swaps the order of sending
and emulates a finite-bandwidth link by queuing packets. It should be
useful to examine an efficiency of network protocols or codecs.

INSTALLATION
Source codes are available from:

http://www.columbia.edu/~at541/src

Unix/Unix like system

To build, unpack the tar file, then type:

./configure

make

Windows98/NT

Microsoft VC++ 6

Open newudpl.dsw under msc\ and just press F7.

Borland C++ builder

Open newudpl_bcb.bpr under bcb\ and just press F9.

I have only tested on SunOS 5.7, 5.8 system and Linux but it should compile
on other Posix-compliant platforms.

OPTIONS

-v
-vv
Verbose output.

With a single -v,

the information of dropping packets by congestion and creating

random packet loss/bit error/out of order will be displayed;

with a second one, receiving and sending packets will also be shown.

-p receiving port : sending port

Specifies the binding ip-port for receiving and sending UDP packets.
Otherwise, default values will be used.

Available range: 1024 – 65535 or 0x400 – 0xFFFF

Default: receiving 41192, sending 41193

-s emulating link speed

Specifies a finite-bandwidth. The speed of Transferring UDP packets
will not exceed this speed. Unit is in kb/s.

Available range: 1 – 50000(MAX_KBPS)

Default: 1000

-e Ethernet speed

Specifies a Ethernet speed on the machine. It is used to calculate a
transmission delay, which makes difference especially when the emulating
link speed is slow.

Available range: 1 for 10M, 2 for 100M, 3 for Gigabit Ethernet

Default: 10M(b/s)

-d delay

Specifies delay time. All the packets will have minimum delay. The
delay for each packet could be varies, depending on the link speed.

For example, -d2 is 2 (sec) and -d1.345678 is 1.345678 (sec).

Available range: 0 – 10(MAX_DELAYSEC)

Default: 0

-q queue-buffer size

Specifies the size of queuing buffer for receiving packets. If you
large this number less likely to have congestion packet loss for the same
link speed.

Available range: 1 – 16384 or 0x1 – 0x4000(MAX_QBUFSIZE)

Default: 8192

-i source host [[ : | / ] port | * ]

Specifies the source host for receiving packets. If the emulator
receives a packet from a different host then the packet will be
rejected. The host name could be either IP number with dotted-decimal
notation (e.g., 128.59.16.8) or the host name (e.g., cs.columbia.edu).
If the port is not specified then it will accept only packets from the
the port 41191, default values, with corresponding source host, but you
could rule out this checking by using ‘*’.

Default: host – localhost, port 41191

Example,

-i dynamo.cs.columbia.edu/32768

-i dynamo.cs.columbia.edu/0x8000

-> accepts packets only from dynamo.cs.columbia.edu/32768

-i diamond.cs.columbia.edu

-> accepts packets only from diamond.cs.columbia.edu/41191

-i 128.59.16.7:*

-> accepts packets any port from disco.cs.columbia.edu
(128.59.16.7)

-o destination host [[ : | / ] port ]

Specifies a destination host for outgoing packets.

Default: host – localhost, port 41194

-B bit error rate

Specifies a rate of generating bit errors for outgoing packets.
The rate is in 1/100000(BITERRDENOM).

Available range: 1 – 99999(BITERRDENOM – 1)

Default: 0

-L random packet loss rate

Specifies a rate of genarating random packet loss for outgoing packets.
The rate is in percentage.

Available range: 1 – 99

Default: 0

-C conditional Gilbert packet loss rate

Specifies a rate of conditional Gilbert packet loss

Available range: 0.0 – 1.0

Default: 0.0

-U average overall Gilbert packet loss

Specifies an average rate of unconditional
overall Gilbert packet loss

Available range: 0.0 – 1.0

Default: 0.0

-O out of order rate

Specifies a rate of randomizing order of packets. The destination host
will receive some packets in out of order in certain rate.
The rate is in percentage.

Available range: 1 – 99

Default: 0

USAGE

To create condition under following parameters,

from: dynamo.cs.columbia.edu(128.59.16.4)/41191

to: disco.cs.columbia.edu(128.59.16.7)/41194

verbose mode

from: any port of dynamo.cs.columbia.edu(128.59.16.4)

to: disco.cs.columbia.edu(128.59.16.7)/32768

with error rate

random packet loss : 7(1/100 per packet)
bit error : 5(1/100000 per bit)

when it is done, all the options precede everything else. Thus
all application programs are extended to handle flexible argument order.

Setting the environment variable POSIXLY_CORRECT disables permutation.
Then the behavior is completely standard.

If the caller did not specify anything,
the default is REQUIRE_ORDER if the environment variable
POSIXLY_CORRECT is defined, PERMUTE otherwise.

REQUIRE_ORDER means don’t recognize them as options;
stop option processing when the first non-option is seen.
This is what Unix does.
This mode of operation is selected by either setting the environment
variable POSIXLY_CORRECT, or using `+’ as the first character
of the list of option characters.

PERMUTE is the default. We permute the contents of ARGV as we scan,
so that eventually all the non-options are at the end. This allows options
to be given in any order, even with programs that were not written to
expect this.

RETURN_IN_ORDER is an option available to programs that were written
to expect options and other ARGV-elements in any order and that care about
the ordering of the two. We describe each non-option ARGV-element
as if it were the argument of an option with character code 1.
Using `-‘ as the first character of the list of option characters
selects this mode of operation.

The special argument `–‘ forces an end of option-scanning regardless
of the value of `ordering’. In the case of RETURN_IN_ORDER, only
`–‘ can cause `getopt’ to return EOF with `optind’ != ARGC. */

If an element of ARGV starts with '-', and is not exactly "-" or "--", then it is an option element. The characters of this element (aside from the initial '-') are option characters. If `getopt' is called repeatedly, it returns successively each of the option characters from each of the option elements. If `getopt' finds another option character, it returns that character, updating `optind' and `nextchar' so that the next call to `getopt' can resume the scan with the following option character or ARGV-element. If there are no more option characters, `getopt' returns `EOF'. Then `optind' is the index in ARGV of the first ARGV-element that is not an option. (The ARGV-elements have been permuted so that those that are not options now come last.) OPTSTRING is a string containing the legitimate option characters. If an option character is seen that is not listed in OPTSTRING, return '?' after printing an error message. If you set `opterr' to zero, the error message is suppressed but we still return '?'. If a char in OPTSTRING is followed by a colon, that means it wants an arg, so the following text in the same ARGV-element, or the text of the following ARGV-element, is returned in `optarg'. Two colons mean an option that wants an optional arg; if there is text in the current ARGV-element, it is returned in `optarg', otherwise `optarg' is set to zero. If OPTSTRING starts with `-' or `+', it requests different methods of handling the non-option ARGV-elements. See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. Long-named options begin with `--' instead of `-'. Their names may be abbreviated as long as the abbreviation is unique or is an exact match for some defined option. If they have an argument, it follows the option name in the same ARGV-element, separated from the option name by a `=', or else the in next ARGV-element. When `getopt' finds a long-named option, it returns 0 if that option's `flag' field is nonzero, the value of the option's `val' field if the `flag' field is zero. The elements of ARGV aren't really const, because we permute them. But we pretend they're const in the prototype to be compatible with other systems. LONGOPTS is a vector of `struct option' terminated by an element containing a name which is zero. LONGIND returns the index in LONGOPT of the long-named option found. It is only valid when a long-named option has been found by the most recent call.
