Re: request for comment: New Version Notification for draft-liu-bmwg-virtual-network-benchmark-00.txt

Hi Vic,

Key points are as following:

   a)The hypervisor type is of ultimate importance to the test results.
      Tester VM must be installed on the same hypervisor type as the
      real DUT. When feasible, tester VM software should be installed on
      a separate, but identical type of, hypervisor.
   b)The VNIC speed will have impact on test results. Tester must
      calibrate against all VNIC speeds to be tested against a real DUT.
   c)VM allocation of CPU resources and memory will affect test results
   d)Packet sizes will affect test results dramatically due to the
      nature of virtual machine

[MD] why don’t we configure tester VM with PCI by-pass mode to access the NIC directly this way there will be no dependency on the hypervisor - which is way better approach then above mentioned.

   e)Other possible extensions of above table: The number of VMs to be
      created, latency and/or jitter readings, one VNIC per VM vs.
      multiple VM sharing one VNIC, and uni-directional traffic vs. bi-
      directional traffic.
[MD] for multiple VM using one vNIC - we should be SR-IOV architecture which also has limited dependency on hypervisor.


Please fix your draft with above suggestions - Please don’t bring in vSwitch in the picture for tester VM - this will always limit the performance to half regardless of mem/cpu availability.

Regards,
Muhammad

Hi all 

We are researching on virtual network and we've submit a draft of benchmark for virtual network.
Hope we can discuss on the mailing list and any comment are big welcome.

Thank you!
All the best!
Vic

Abstract:
   As the virtual network have been wide establish in IDC. The
   performance of virtual network has become a consideration to the IDC
   managers. This draft introduce a benchmarking methodology for
   virtualization network performance.


                                                                                  


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
