COMMENT:
----------------------------------------------------------------------

Thanks for your work on this draft.  I just have one question that was
raised in the SecDir review:

Was there any thought to how the tcpinc efforts might affect the ability
to gather measurements?
http://www.ietf.org/mail-archive/web/secdir/current/msg05726.html

It doesn't have an impact on this draft yet, but could in the future.

Section 6.2.1 Queue/Scheduler Individual Tests Overview
I understand that is not finished work, but do we need to say a few words
about codel and pie
http://datatracker.ietf.org/doc/draft-ietf-aqm-pie/ and
http://datatracker.ietf.org/doc/draft-ietf-aqm-codel/

- More of a transport AD question:
"To this end, the stateful tests will use TCP test patterns to emulate
applications."
Do we need to emulate any applications on SCTP test patterns?
Asking the transport ADs about which deployed protocols use SCTP, their
answer was: WebRTC, SS7 signalling in 3gpp mobile networks.

Subject: RFC 6982: Improving Awareness of Running Code: The Implementation Status Section

Dear WG chairs,

During the IESG retreat this week, we discussed running code. We would like to bring your attention to this RFC: 6982, "Improving Awareness of Running Code: The Implementation Status Section" (experimental).
You can review section 4 for an explanation of the benefits.
Interestingly, out of the 1918 current drafts, only 32 use that "Implementation Status" section.

Please advertise this capability within your WGs.

Hello BMWG,
        Per the minutes of IETF 92, I see there is an action for myself, and I'm closing that loop now. :)
        During the meeting in Dallas, there was support for this draft within the room; I'd like to ask the list now to consider adopting Al's virtual net draft as a WG item. Please, read the draft, and submit your comments and thoughts to the list, here.

Regards,

Comments on draft-morton-bmwg-virtual-net-03

Hi Al,
 
I read the draft in detail and first off, want to state that I fully support this work in BMWG.
 
Here are my first round of comments:
 
1. Section 2, paragraph 2.  I think it is also essential to benchmark a "bare metal" software network function so that the performance of a physcial device, software version on bare metal OS, and software version in VM can be compared
 
2. Section 3.2.
 
- It would be good to expand what is meant by Infrastructure Virtual Network.  Since the VM running on Hypervisor is a VNF, this was not clear
 
- "number of VNF components in the service function chain"  -->  Should this be more of a defintion of the service function chain itself, from which the number of components becomes apparent?  Service function chain would then be clearer with an example as well
 
3. Section 3.3, item #4
 
I am not sure if this is the spirit of this bullet, but what I have observed in VM based applications is the performance degradation when a VM is rotated as others are added.  I think it will be important to define a test which benchmarks the performance of say a switch under RFC 2544 conditions as new VMs are added by the Hypervisor.  This has to do with concurrency and capacity testing for which I have comments a few points below
 
4. Section 3.4,  I think it should be recommended that physical hardware based tester should be used as the first choice for the test traffic device and that a separate tester VNF can be used but with stronger language that this then requires that the tester VNF function be independently benchmarked against it's physical counterpart
 
5. Section 4.1, same as comment #1, add bare metal OS test of software network function
 
6. Section 4.2, paragraph 1.  I think an example of a performance results from internal OS would help here.  Did you have in mind network counters of dropped packets, etc?
 
7. Section 4.4.  This is my first exposure to the 3 x 3 matrix and I this is interesting.  I think what is needed is a section that describes a technique to document the concurrency of VNFs within a hardware platform and the performance / breaking points.
 
An example would be a firewall VNF benchmarked as a single instance and then how many Firewall VNF instances can exist concurrently within the given hardware platform before performance starts to degrade.
 
Then we would get into VNF functions A,B,C and how many of each can exist concurrently within a platform, so there might be a reporting matrix that shows functions A, B, C as columns and rows which show the various combinations of each that can be hosted with 100% performance for each combination (I hope this makes sense as this might be complicated to explain in an email).
 
Again, fully support this work and hope that these comments are helpful.
 
Regards,
Barry
