[mpls-linux-general] Measure the delay jitter of video stream over MPLS network?

[Jing S. <js...@ca...>]

Hi:

Execuse me for my stupid question, but I really need help
on this question.

I've just setup a little test bed with MPLS & QoS enabled.
I want to measure the effect of QoS enabled MPLS channel
on video streams. I hope the test should be as simple as possible.

I've download a little tool named mpeg_video
which is a mpeg-1 decoder. I place the mpeg-1 files
on one end of the testbed(linux)  and mpeg-1 decoder on the other
end ( Solaris box). The decoder use NFS to fetch the content to play.
After reading the source code of the mpeg-1 decoder I find I
can just record the start and stop time of each frame, while I want to
measure the delay and delay jitter of each stream. And, I don't know if
there
is a free tool  can be used to generate a  graph of jitter-frame
relationship
from raw data.

Is there any person would like to do me a favor on this question?

Thanks a lot .

Regards

James Shen

Let me check my bookmarks one second:
 http://www.antd.nist.gov/itg/nistswitch/extreme.html

and related. Checking out the main nistswitch page (the bsd
implementation) a while ago, IIRC, I saw some RSVP-TE code for the ISI
daemon (which else?). Wasnt there some code for linux's tc on the main ISI
site?

 Where those the guys you are talking about?

Hi Everybody,

I would appreciate if anybody can guide me through following:

I am a new comer to MPLS, and want to start with following topology;


Ingress----------------------LSR-----------------Egress
192.168.100.3            eth1   eth2             192.168.200.3

                 192.168.100.1  192.168.200.1


I have configured the LSR as under ;

mplsadm -v -L eth1:0
mplsadm -v -L eth2:0

mplsadm -A -B -I gen:16:0 -o gen:16:eth1:ipv4:192.168.100.3
mplsadm -A -B -I gen:16:0 -o gen:16:eth2:ipv4:192.168.200.3

Please see where I am wrong and kindly advise me with the correct commands 
in detail while realizing my new entrance into MPLS technology.


Thanks in Advance

No RSVP-TE (yet).  I have talked to a couple of people who were interested
in doing the work (I don't have time) but I haven't herd from any of them
in quite a while.

If anyone is out there working on RSVP-TE, let me know :-)

As for Ethereal decoding RSVP-TE, yes it can decode RSVP-TE.

Hi,

I am having few problems in setting-up Linux box for MPLS command scripts.

I have isntalled kernel 2.4.1 and Mpls 0.802 on my linux box.
The scenerio is ;


  Ingress Router-------LSR-------Egress Router

LSR is a Linux box with MPLS on it.I want to enable mpls label assignments 
and packet forwarding on Linux box so that it can push labels forward.

I need cofniguration only for Linux box/LSR.
How can I verify that I have done correct configurations ?
I am using Ethereal, is there any other command I can use to verify it like 
mplsadm -d or dmesg etc. ?

I will appreciate if anybody can come-up with a very comprehansive rely.

Hi,

Can anybody tell me if MPLS linux supports RSVP ??

In fact I went through Sourceforge.net site and found that RSVP is still not 
supported on MPLS Linux.Can I rely on this information as when I capture 
packets through Ethereal on my MPLS linux Router,I can see RSVP Path and 
Recv. messages.

Please clarify it.

If you comment out -DMPLS_LINUX in the portable directory, you should be
able to compile ldp-portable without havine mpls-linux installed.




I REMOVED THE option -DMPLS_LINUX from the Makefile and tried to
compile. It still does not compile as it is unable to find "mpls.h". Do
i have to make any other changes also to take into consideration.

In the mapping message there is nothing prohibiting multiple FECs to be sent
in the same message.  I do not think you can send multple FEC,Label pairs.
In other words a mapping message can contain 1 (and only one) label TLV but
can contain many FEC elements (with in one FEC TLV).

I have never testes this functionality, but I believe I attempt to handle this
case.

Take a look at ldp_state_func.c:ldp_state_proces() you'll see I attempt to
cycle through all of the FEC elements in the FEC TLV.  Like I said I have
never tested this, so I'm pretty sure it's not going to work, but it is
atleast on the right track :-)

Does the LDP allow to have multiple {fec, label}
bindings in a single mapping message?

I could not get the answer from the RFC. I don't
think your implementation does it.

You're doing it correct. The label space is a responsibility of the "porting"
layer.  So in this case ldp_linux should be the one to add the label space. 
I wouldn't take much work to do it.  Just add the call (look in mplsadm.c for
an example) to ldp_linux.c:add_interface().  For now always assing every
interface to label space 0, later on the label space could be a parameter to
the 'add interface' command.

Do you think your up for it?  If not let me know and I'll add it to my
todo list :-)

You will want to get mpls-linux-0.993.tar.gz and use CVS to get the latest
ldp-portable code.

You will need multiple LDP speaker before you will know if LDP is working
right :-)

There is some documentation in ldp-portable's CVS.

Turn on MPLS kernel debugging:

mplsadm -d

This command toggles (once turns on, the next time it turn off) MPLS
kernel debugging.  You may need to run:

dmesg

To see the output.

You will want to upgrade to 0.993 if you plan of doing and TCP streams over
the LSPs.

[mpls-linux-general] ldp-portable labelspace setting

[Giovanna P. (ERI) <Gio...@er...>]

Dear Mr.Leu,

we are trying a version of your ldp-portable software, updated with CVS repository files.
The software is currently running on linux 2.4.4 patched with mpls-linux-0.990.
Label distribution in unsolicited mode works actually very well, except we noticed that ldp doesn't set labelspace to 0.

At present we simply skip the problem running the mpls command
mplsadm -L eth0:0
from console

but we were wondering if maybe we are missing something and it is possible to 
get the labelspace settled from ldp-portable itself,

Hi


I am a new comer to MPLS and using linux box with kernel 2.4.1 and
mpls-0.990 installed on it.

My problem is that I did try couple of options to enable mpls label
generation on the linux box but seems not working properly.

Here is the scenerio ;

I just want one linux box to work as an LSR initially, with ports eth1 &
eth2 connected with some testing device i.e Ixia or Smartbit two ports.Ixia
Port 2-01 will act as an Ingress Router(Simulated) and Port2-02 as an Egress
Router.

Ixia Port 2-01.........192.168.100.3  connected with Linux box(LSR) through
                       eth1 having IP address....192.168.100.1

                       eth2 having IP address....192.168.200.1

I have configured Ixia properly.

I did following on linux box ;

mplsadm -v -A -B -O gen:16:eth1:ipv4:192.168.100.3 -f 192.168.100.3/32

mplsadm -v -L eth1:0
mplsadm -v -L eth2:0

I am using Ethereal on linux box and when ping the Ixia ports, can only see
RSVP Peth message frames and RSVP Recv frames.
Moreover,how can I verify if the linux box's interfaces are configured with
MPLS properly ?Please guide me(if Ixia box is confusing anybody,then just
guide me
if I am wrong in configuring an LSR to enable label generation only)


I just want you to please confirm if I configured linux box properly for

from http://www.sourceforge.net.

I have some problems, I just have a PC which runs Red Hat 7.0 , I have
no more computers and ethernet cards to establish small test network.
So, I can not set up the mpls-linux-0.990.tar package.

But I am very interested in the "ldp-portable-0.060.tar" package, I have
untar this package in my Linux Read Hat 7.0. I just want to install this
"ldp-portable-0.060.tar" package,
I have read the \ldp-portable-0.060\port\README file.

But, I still have some questions:

Question (1):
Can I compile this Linux implementation by typing make command? I mean
can I Compile this package without installing  the "mpls-linux
mpls-linux-0.990" package? In other word, Can the
"ldp-portable-0.060" package run on Red Hat Linux 7.0 platform
separately?


Question (2):
How to check whether the installed LDP package works or not if it works
well after installation?

Question (2):
Where can I find the documentations in detail for this
ldp-portable-0.060 package?


You help is highly appreciated!
Thanks in advance and I am looking forward to hearing from you.

Sincerely!

Jack Zhao

Hey Yon, good to see you're still alive :-)

No such luck :-(

I'm not sure what this one is, I'll have to try it myself and see if I can
reproduce it.

I attempted to remove all of the references to 'tag' and 'tdp' and add
a couple of configure commands (ingress and egress filtering).
It looks like I horked up the show commands though.  I poked around in the
code last night and was unable to figure our what I did wrong.  If you have
some time to look at zldp_cli.c I would really appreciate it.

Hmmm.  It was working.  Then again I usually write one by hand.  I'll
look in to this as well.

Sorry about that ;-)

I'll try to get some more of the zebra stuff working.  I prefer working
with ldp_zebra as opposed to ldp_linux, so it will get fixed sooner ;-)

BTW thanks again for doing the initial zebra work, with out that kick start
I'd still be concentrating on using ldp_linux.

[jk s. <jk...@us...>]

Hi James,
I did configure two nodes according to README.example. To check whether
the MPLS label switching works or not. I used ping A from node B. To my
surprise what ever may be the incoming and outgoing label the node is
discovered. That means after the label is addeded to IP packets at node A=
,
node B decodes it and respondes to it immaterial of Label (
incoming/outgoing).

May I request U to give me the methodology by which I can confirm that MP=
LSadm
setup configuration is working ( as per README.example ).

Can anybody help me out if they worked on mpls-linux-0.990 by responding =
to
this mail. My main purpose is to demonstrate the mpls labeling.

thankx

If you tring to ingress filter based on bandwidth then README.ingress
is the correct place to start.  If your just trying to build a simple
LER/LSR/LER example utils/README.example is the one you want to look at.

I haven't tried ingress filtering in a long time.  Could one of the origi=
nal
users of it verify that it still works?

[Yon U. <uk...@rz...>]

Hello,

 I shall comment inline to your post. If the problems went away with
0.993, consider this just a coffeine induced halucination.

 On a general note: I did the original code, but haven't touched it since
it got included in the CVS repository. It was buggy (100% alpha). I'm
getting a computer (if dell can wipe its virtual ass and hurry up getting
my money), so I shall be coding some more in the summer.

Please, when getting a core dump, start the program in gdb, as in:
"gdb ./ldp_zebra"

on the  prompt type run, followed by the parameters:
"run -P 2610"

and when it bombs, just type
"bt"
for backtrace, which prints a trace all the way back up the stack.

I can't tell. Sounds like some commands where registered twice to the
zebra cli handler. I did some preprocessor macros for registering both the
tag and mpls commands, could be this. (I only had some '99 vintage
paper docs on cisco cli when I started, they where about tags, not labels,
I think tag commands should be removed now)

 Yep, right. IIRC the save config function and the defined config
functions where neither a subset of each other, TBD.

Please note the date, this was my working copy. Sort of a monster.

 Wanna pay me for coding this? <eg> No, but seriously, if I manage to
rewire my neurons for Jim's preferred C formatting style, some work will
be done on this in the next 3 months.

[mpls-linux-general] mpls-linux 0.993

[James R. L. <jl...@mi...>]

I guess release 0.992 was just not meant to be.  I have release 0.993
which is the same as 0.992, but has the correct patch this time :-)

Sorry to those who downloaded 0.992.
