NS3-dev and MPLS

[netwo...@gmail.com]

hello fellow developers,

I got a new assignment to work on MPLS. (not gonna talk about whats the assignment)

i went to source folder in ns-3,26 and found nothing containing MPLS or similar to that.

then i got new about ns3-dev in which MPLS patch was/is available. 

so i installed the ns3-dev by these line:

hg clone http://code.nsnam.org/ns-3-dev

hg clone http://code.nsnam.org/ns-3-allinone

cd ns-3-allinone && ./download.py

till now everything is fine. then i found link to install MPLS Patch or file to ns3-dev

https://code.google.com/archive/p/ns-3-shop/wikis/InstallationOfMplsModule.wiki

and followed the steps there:- 

python mpls.py install

on the 1st line i got an error

File "mpls.py", line 196, in <module>

    run()

  File "mpls.py", line 186, in run

    install(*argv[2:])

  File "mpls.py", line 93, in install

    if load_files({'[local_path]': local_path}) is not None:

  File "mpls.py", line 145, in load_files

    hg.clone(u, {}, source=remote_path, dest=local_path)

    srcpeer = peer(ui, peeropts, source)

    return _peerorrepo(rui, path, create).peer()

  File "/usr/lib/python2.7/dist-packages/mercurial/hg.py", line 102, in _peerorrepo

    obj = _peerlookup(path).instance(ui, path, create)

    inst._fetchcaps()

  File "/usr/lib/python2.7/dist-packages/mercurial/httppeer.py", line 57, in _fetchcaps

    self.caps = set(self._call('capabilities').split())

  File "/usr/lib/python2.7/dist-packages/mercurial/httppeer.py", line 171, in _call

    fp = self._callstream(cmd, **args)

  File "/usr/lib/python2.7/dist-packages/mercurial/httppeer.py", line 118, in _callstream

    resp = self.urlopener.open(req)

  File "/usr/lib/python2.7/urllib2.py", line 410, in open

    response = meth(req, response)

  File "/usr/lib/python2.7/urllib2.py", line 523, in http_response

    'http', request, response, code, msg, hdrs)

  File "/usr/lib/python2.7/urllib2.py", line 448, in error

    return self._call_chain(*args)

  File "/usr/lib/python2.7/urllib2.py", line 382, in _call_chain

    result = func(*args)

  File "/usr/lib/python2.7/urllib2.py", line 531, in http_error_default

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)

urllib2.HTTPError: HTTP Error 404: Not Found

that's still fine because there is also manually addition step.

i also tried that. and 

BOOM another ERROR

what should i do now?

Hi,

If you read the wiki page carefully, you would see that the supported ns-3 release is significantly old

Place it to ns-3-dev(ns-3.11) folder

when you are trying to install in ns-3.26. 

Even if you download the source code and try to manually merge it, it would require significant effort since both the structure and API of ns-3 has changed.

Regards,

K.

Hi,

Sorry for mistake from my end. 

i am not familiar with ns-3-dev. so NO SIR CAN'T DO THAT.

if you have any other information about MPLS for NS3 (can work above ns-3.17).

i will be much obliged.

Thank you again Mr. K
