Dear Friends, I was using Qosr and encountered the foll problems.... For example suppose there is a link with bandwidth 10Mb and I want to reserve 10Mb, i get the message bandwidth reservation failed. But when I make reservation for 9.9Mb the reservation takes place. I was wondering how could i modify my QOSR code to make sure tht 10Mb is reserved when 10Mb is asked for and there is 10Mb space available on the link. I have attached the code that I was using, please do help me and lemme know wht changes i can do to make this work. Thanks a lot, Take care, Sujith ----------------------------------------------------------------------- The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives.Anyone who has never made a mistake has never tried anything new.

Dear friends, Can anybody please send me a simple code wherein they have implemented the Get bw procedure...I just wanted to understand the functioning of Qosr in NS...and how to go about writing tcl scripts for QoS routing... Thanks, Regards, Sujith |

You might need to install ns2 first and untar qosrns package in the ns2 = directory. Then, you should be able to run ./configure The "configure" = is included in ns2 package not qosr package. =20 Br, Peng -----Original Message----- From: pj...@gy...

Hi, Im working with ns-2.1b9a all in one package on Linux. Plus qosrns-0.2-pre2-ns2.1b9 project to simulate Qos IP network. My problem is that I got the following error when running some scripts : Segmentation fault Core dumped Although that my network is only 6 nodes & 10 links (not so large..!). Maybe Something is missed up in the implementation of the package (qosrn). Do anybody have idea about this error ..?!

Hi, I noticed that QOSPF does not react to link dynamics, for example: $ns rtmodel-at 0.9 down $n0 $n1 the QOSPF cannot realise that the link is down even when you release the session at the same time and create another one just afterwards QOSPF tries to use the same link which is down. Have anybody got any ideas about it? I look forward to your reply, Kind Regards Costas Samdanis __________________________________________________ Do you Yahoo!?

Hi, The resources still reserved by cd-ldp. to release the ressources you can apply the function : "$MPLSnode send-crldp-release-msg $lspid" modified like outlined in : http://sourceforge.net/mailarchive/forum.php?thread_id=805544&forum_id=8130 Tell me if you find any problem.

Hi, In QOSPF if you stop (e.g $ns at 1.0 "$cbr stop") the flow traffic the bw is still reserved. Do anybody know how to release the bw when the traffic of the flow stops?

Hi, I have downloaded the QOSPF for ns2. I computes the explicit route and implements source routing using that explicit route. Have anybody got any idea on how to change this source routing to distributed routing.

Hi,
I looked the example qosr.tcl, and i was thinking if
it is possible to implement elastic reservations.
Specifically, I mean, whenever QOSPF do an update and
a better route exit to trigger an update also in the
reseavation of the path and recompute the eroute. For
example,
n1
/ \
5Mb / \ 5Mb
/ \
/ 2Mb \
n0----------n2
1. a 2.5 Mbps session between n0 and n2 fid 1 (path
taken n0-n1-n2)
2. a 1.5 Mbps session between n0 and n2 fid 2 (path
taken n0-n2)
3. a 1.5 Mbps session between n0 and n2 fid 3 (path
taken n0-n1-n2)
4. a 3.0 Mbps session between n0 and n2 fid 4
(unsuccessful as bandwith not available so forwarded
as best-effort fid 0)
If fid 1 and fid 2 stop after 2.0sec, fid 4 which was
unsuccessful so far, to be able to make a new
reservation in the path n0-n1-n2 after the 2.0secs
Kind Regards

Hi all,
The problem I have been talking about recently has been solved.
The cause of this problem is that the "collect-resource" function does not
call "bw-changed" after modification of "usable-bw_". After making changes to
the source files of ns MNS/OSPF fine. The changes are as followed (I attached
the necessary file also).
Rgds..
Tarek.
file : ~ns/tcl/mns_v2.0/ns-mpls-cbq.tcl
SimpleLink instproc collect-resource {flowid cbq_qtype} {
$self instvar usable_bw_
set cbqclass [$self get-class-in-cbq-pool $flowid]
if { $cbqclass == -1 } {
return
}
set link_bw [$self get-link-bw]
set extra_bw [$self set usable_bw_]
set cbqclass_bw [$cbqclass allot]
self set usable_bw_ [expr $extra_bw + $cbqclass_bw * $link_bw]
# Modified by Tarek Nadour
set QOSPFenable [RtModule/MPLS set enableQOSPF]
if {$QOSPFenable != 0} {
set rtqospf [ [$self src] get-module "QOSPF"]
$rtqospf bw-changed
}
# option: cbqclass bw okborrow maxidle prio xdelay
$cbqclass CBQ-set-papameter 0.0 ignore ignore ignore ignore
set oldqueue [$self get-queue-in-cbq-pool $cbqclass]
$oldqueue reset
$self CBQ-change-flowid $cbqclass -1
$self update-flowid-in-cbq-pool $cbqclass -1
}

Hi all,
The problem I have been talking about recently has been solved.
The cause of this problem is that the "collect-resource" function does not
call "bw-changed" after modification of "usable-bw_". After making changes to
the source files of ns MNS/OSPF fine. The changes are as followed (I attached
the necessary file also).
Rgds..
Tarek.
file : ~ns/tcl/mns_v2.0/ns-mpls-cbq.tcl
SimpleLink instproc collect-resource {flowid cbq_qtype} {
$self instvar usable_bw_
set cbqclass [$self get-class-in-cbq-pool $flowid]
if { $cbqclass == -1 } {
return
}
set link_bw [$self get-link-bw]
set extra_bw [$self set usable_bw_]
set cbqclass_bw [$cbqclass allot]
self set usable_bw_ [expr $extra_bw + $cbqclass_bw * $link_bw]
# Modified by Tarek Nadour
set QOSPFenable [RtModule/MPLS set enableQOSPF]
if {$QOSPFenable != 0} {
set rtqospf [ [$self src] get-module "QOSPF"]
$rtqospf bw-changed
}
# option: cbqclass bw okborrow maxidle prio xdelay
$cbqclass CBQ-set-papameter 0.0 ignore ignore ignore ignore
set oldqueue [$self get-queue-in-cbq-pool $cbqclass]
$oldqueue reset
$self CBQ-change-flowid $cbqclass -1
$self update-flowid-in-cbq-pool $cbqclass -1
}

qosrns-0.2-pre2 for ns-2.1b9 has been released you can get it from www.sourceforge.net/projects/qosrns please report any bug reports / installation problems to this list -- Amardeep Singh |

Hi all, A new version of qosrns has been released. I have uploaded qosrns-0.2-pre2-ns2.1b8a.tar.gz to the project page on sourceforge. This version will work with ns-2.1b8a. I need to make some changes for it to work with ns2.1b9. I would be releasing that tomorrow. This release comes with mns (mpls implementation for ns) extended with qospf support. For an example, see test-constraint-routing-qospf.tcl in tcl/ex directory. Please mail this list for any installation related problem. -- Amardeep Singh |

Hello, I've compiled ns with qosrns files and works perfectly ! Thanks. Tarek.
