[nox-dev] Kernel Mininet didn't work on debian squeeze
I would like to know if is there a mininet kernel image that works with debian squeeze? because, current kernel image didn't install on debian squeeze, following the errors printed: dpkg-deb: `linux-image-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb' is not a debian format archive dpkg: error processing linux-image-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb (--install): subprocess dpkg-deb --control returned error exit status 2 dpkg-deb: `linux-headers-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb' is not a debian format archive dpkg: error processing linux-headers-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb (--install): subprocess dpkg-deb --control returned error exit status 2 Errors were encountered while processing: linux-image-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb linux-headers-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb Fernando N.

[nox-dev] packing openflow message
Hi,I would like to pack openflow message.so, I am trying to pack ofp_queue_stats_request,ofp_queue_stats.if I want to use ofp_queue_stats_request,struct ofp_queue_stats_request{uint16_t port no;uint8_t pad[2];uint32_t queue_id;}ofp_queue_stats_request oqs;oqs.pack();send_openflow_command();Is it correct way ?please let me know in detail having a example.
Best Regards,

Re: [nox-dev] Bandwidth Measurement.
Hi, I think the closest thing that openflow can provide would be information about how many bytes have been sent on one side and received on the other side of a link. So you could infer an approximation of active rates on the link by polling 2 neighboring switches from NOX at some regular intervals. This can not be very accurate because there are factors like round-trip-times for the requests/replies from NOX to the 2 switches and back, these times will be different, also there are packets travelling between the switches that should be taken into account etc. But this is definitely a place to start if you want to do such measurements from NOX. The "monitoring" component on the destiny branch (netapps/monitoring) does something like that (it regularly polls all switches for all kinds of statistics), so it's a good place to look at. 2011/6/29 Min-Hyup KANG > Hi, > > > I would like to measure bandwidth between switches. > > > I am reading openflow spec 1.0, but there are not existing exactly. > > > please can you give me some tips ? > > > > Best Regards, > Min-Hyup KANG > > > ___ > nox-dev mailing list > nox-dev@noxrepo.org > http://noxrepo.org/mailman/listinfo/nox-dev > > ___ nox-dev mailing list nox-dev@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev
