Here is a summary of the poll. I put down Aaron as having the sysvirt
position, though he didn't respond directly to the poll. Anyone who
listed both or neither is also listed.

The totals are 23 votes total:

			14 61%	network virtualization
			 4 17%	system virtualization
			 3 13%	both
			 2  9%	neither

I.e., there appears to be a reasonably majority in favor of focusing on
network virtualization at this time. This does not preclude considering
systems issues, nor does it preclude including systems aspects in the
charter at a later time.

I would like to proceed with proposing a charter with this focus, which
I will post later today. If you have an issue you think should be
included, please either post to the list or to me directly, or post in
response to the proposed charter.

We are arranging a 'bar bof' in Hiroshima to continue the discussion
face-to-face, but the key focus at this time should be getting the
charter nailed down so we can get to work.

Joe (volunteer interim chair ;-)

Topic:

Network virtualization is the technology that allows the simultaneous =20=

operation of multiple logical networks (also known as overlays) on a =20
single physical platform. Network virtualization permits distributed =20
participants to create almost instantly their own network with =20
application-specific naming, routing, and resource management =20
mechanisms such as server virtualization enables users to use even a =20
whole computing center arbitrarily as their own personal computer. =20
Recently, network virtualization received tremendous attention since =20
it is expected to be one of the major paradigms for the future =20
Internet as proposed by numerous international initiatives on future =20
networks, e.g. PlanetLab (USA, International), GENI (USA), AKARI =20
(JAPAN), OneLab2 (Europe) and G-Lab (Germany).

Network virtualization is a rather new technology with performance =20
aspects not yet eminent but expected to grow with its spreading =20
application, the scaling of this new type of virtual networks, and the =20=

dynamics of invoking them. These new performance aspects may comprise =20=

the quality of isolation, fairness among virtual systems, the location =20=

transparency of virtual services, the quality of synthetic virtual =20
resources, and the scalability of the composition of virtual network =20
and service and of the management mechanisms for virtual network and =20
their communication patterns.
As a follow-up of the successful 20th ITC Specialist Seminar on =20
Network Virtualization (Hoi An, Vietnam, 20.-21. May 2009), the =20
objective of this special issue of the IJCNDS is to address =20
techniques, architectures, performance models, and performance =20
engineering methods leading to real world network virtualization =20
solutions that provide users with efficient techniques for creating =20
and operating their own high performance virtual network.

Topics of interest are amongst others, but not limited to:
- Performance issues of virtualization techniques on routers and end =20
hosts
  o Isolation and fairness for the resource access among multiple =20
guest systems on a single host
  o Performance issues of virtualized operating systems and server =20
virtualization
  o Performance metrics for virtualized hosts or routers
  o Measurement techniques, e.g. for the parallel throughput on a =20
single host
  o Performance evaluation of virtualized packet switching technologies
  o Middleware for virtualization
- Performance issues of bandwidth and resource virtualization techniques
  o Media access mechanisms for network virtualization in wireline and =20=

wireless environments
  o Performance of Multiqueue Network Interfaces
  o Fairness among overlays using the same transmission system
  o Scheduling mechanisms for virtualized connections
  o Models for resource contention between virtual networks
- Performance issues of overlays for future network architectures
  o Performance of overlay composition
  o Performance assessment of grid computing platforms
  o Performance of content/data-oriented routing
  o Stability, robustness and resilience of overlays, virtual networks =20=

and self-organizing mechanisms
  o Static and time-dependent topology/resource/user models for overlays
  o Metrics for adaptation and dynamics in overlays
  o Mechanisms, Capabilities and Accuracy of Network Coordinate =20
Systems (NCS)
  o Traffic engineering for virtual networks
  o QoS and Quality-of-Experience (QoE) in overlays
- Performance of virtualized transport mechanisms
  o Performance of multi-source download
  o Path selection, path splicing in overlays
  o Engineering for path combination
- Performance of virtualized services and virtualized applications
  o Traffic models of virtualized services and applications (e.g. =20
w.r.t. QoE)
  o Performance of security mechanisms in virtualized network =20
environments
  o Performance of virtualization technologies for Grid Computing and =20=

Service Oriented Architecture (SOA)
o Performance of Virtual Storages
- Virtual Test Labs and Network Federation
  o Capability and performance and of network emulation
  o Performance of virtual network management mechanisms
  o Performance and management of federation points / gateways / =20
interconnects
  o Measurements in deploy virtualized networks

Subject: Re: [nvrg-bof] poll on charter focus - RESPONSES DUE OCT 23
Reply-To: [email-masked]

I already voted for b), but if rough consensus is for a)
let's start there.

But we cannot decouple easily a and b.
As an example, in addition to roting functionality,
in virtualization software there is an internal "network
switch/bridge/repeater" and newtworks can be created
inside the virtulization layer.

It will be interesting.

I'd prefer the RG to focus on network virtualization.

Contrary to what some of the previous posters wrote, I also believe =
there are quite a number of opportunities for pre-standardization work. =
E.g., our work in the 4WARD project includes the deployment of virtual =
networks across provider domains. To that end, we are developing a =
number of inter-provider interfaces, protocols, and data models that =
will eventually require standardization if we hope that some of these =
technologies will see real-world deployment.

That said, I have some concerns that "network virtualization" as =
presented here might be scoped to narrowly. Servers, caching nodes, =
wireless infrastructure etc. are all crucial parts of the network =
infrastructure. Excluding everthing but routers and links would be too =
limiting. This does not mean that the RG should look into OS =
virtualization etc.

BR,
Stephan.

I would like to show my preference for choice a), but as said before, 
network virtualisation cannot be magically done without the support of

I support both topics as subjects of Research Group, but do feel that we sh=

Hi, all,

Work on updating the charter proposal hasn't progressed since the last
meeting in Stockholm. Aaron and I exchanged some ideas a month ago, and
Aaron asked for people to voice their position above then. I haven't
heard any discussion.

In order for this group to move forward, we need to decide what our
focus is. So, to that end, I'll summarize the current views:

       a) virtualization of networks
               Joe

       b) virtualization of systems,
       incl. networks, hosts, services, storage, sensors/actuators
               Aaron

Can everyone on this list please try to post a short not indicating your
view of where this group should focus ASAP, no later than Friday Oct 23.
That should help us gauge how to proceed.

Thanks,

Joe (just as a list member)

Hi all,
I would support b). Virtualization helps in decoupling
functionalities from hardware (e.g. routing), therefore
I would not decouple the two areas. Unless we want just
to talk about bits (and not about bits handling).

I feel option a) is a bit tight for IRTF RG discussion.
Therefor I support option b).

Exactly, although the QoS mechanism that we're proposing are not
necessarily limited to the LAN.
If you're interested, I would be happy to chat with you (or others)
about the current proposals to extend OpenFlow to include QoS support.

Also, in addition to bandwidth, there are other (maybe less obvious)
network resources that need to be isolated, e.g., forwarding table
entries, switch/router CPU, and who controls the traffic-- what we
call "flowspace".

IP tunnels between eGENI islands are definitely one direction we're
pursuing.  That said, we're also trying to deploy eGENI on backbone
research networks like Internet2.   So, the idea is: if there is a
consistent policy across eGENI islands and the islands are directly
connected (i.e., Stanford peers with Internet2) then it should be
possible to have a consistent virtual "slice" across both LAN and WAN.

We're actively trying to set up a demonstration of this and I'm hoping
that we will be able to show some of it at GEC6.

Subject: Re: [nvrg-bof] poll on charter focus - RESPONSES DUE OCT 23

Our research group is more interested in system virtualization since
we would like to see networks go beyond providing connectivity and QoS
on that connectivity. It is true that there are many end-host
virtualization ideas led by other forums and data-center experts. But
still, it would be more interesting for our group to participate in a
research activity that would include the virtualization of (maybe
limited to in network) storage and processing besides forwarding. We
need coherent mechanisms for resource identification, allocation,
monitoring, and management over wide-area networks. We also need
mechanisms that can describe the degree of virtualization (e.g., what
is the isolation model for different resources at different autonomous
networks).

Hi Rob,

I guess FlowVisor could rewrite the OpenFlow protocol coming from the virtu=
alized controllers to insert LAN QoS, right? That would enforce isolation f=
or Enterprise GENI.

I was mainly thinking about the WAN case. My understanding from a discussio=
n in the PlanetLab GENI meeting in Seattle is that the plan was to use IP o=
verlays between Enterprise GENI networks.

g their SLAs fufilled.

Fwiw, I'm working in GENI with my FlowVisor virtualization layer
project (tech report newly available at
http://www.openflowswitch.org/wk/index.php/FlowVisor if anyone is
interested), and while I'm not sure where you draw the line between
"over the top" vs. "close to the metal", FlowVisor (intuitively to me
at least) would seem to run close to the metal and is not really an
overlay like X-Bone.

Cheers,

Subject: Re: [nvrg-bof] poll on charter focus - RESPONSES DUE OCT 23

Dear Joe, all,

    our team is interested in virtual networks,
but not in virtualization of systems.

    We are currently involved in a project called
Manticore (some of you probably know it):
  http://www.i2cat.net/en/projecte/manticore-1

 From this project, we can see some aspects that
in our opinion need an standardization:

    - There is a problem when different vendor devices
should be in the same virtual network: API or protocol
definition required, in a similar way that SMTP does, but
now considering the middleware.
    - There is a problem in the interoperatibility between
virtual networks: Routing, addressing, QoS parameters, etc.

    We are very interested in participate actively, but we
don't see clearly how. We belong to this distribution list
since summer 2008, and we are progressing too slowly. How
can we (all) boost the target and the work plan ?

    Hope it can be useful.
      Best regards,

        Xavier and Felipe,

Topic:

Network virtualization is the technology that allows the simultaneous =20=

operation of multiple logical networks (also known as overlays) on a =20
single physical platform. Network virtualization permits distributed =20
participants to create almost instantly their own network with =20
application-specific naming, routing, and resource management =20
mechanisms such as server virtualization enables users to use even a =20
whole computing center arbitrarily as their own personal computer. =20
Recently, network virtualization received tremendous attention since =20
it is expected to be one of the major paradigms for the future =20
Internet as proposed by numerous international initiatives on future =20
networks, e.g. PlanetLab (USA, International), GENI (USA), AKARI =20
(JAPAN), OneLab2 (Europe) and G-Lab (Germany).

Network virtualization is a rather new technology with performance =20
aspects not yet eminent but expected to grow with its spreading =20
application, the scaling of this new type of virtual networks, and the =20=

dynamics of invoking them. These new performance aspects may comprise =20=

the quality of isolation, fairness among virtual systems, the location =20=

transparency of virtual services, the quality of synthetic virtual =20
resources, and the scalability of the composition of virtual network =20
and service and of the management mechanisms for virtual network and =20
their communication patterns.
As a follow-up of the successful 20th ITC Specialist Seminar on =20
Network Virtualization (Hoi An, Vietnam, 20.-21. May 2009), the =20
objective of this special issue of the IJCNDS is to address =20
techniques, architectures, performance models, and performance =20
engineering methods leading to real world network virtualization =20
solutions that provide users with efficient techniques for creating =20
and operating their own high performance virtual network.

Topics of interest are amongst others, but not limited to:
- Performance issues of virtualization techniques on routers and end =20
hosts
  o Isolation and fairness for the resource access among multiple =20
guest systems on a single host
  o Performance issues of virtualized operating systems and server =20
virtualization
  o Performance metrics for virtualized hosts or routers
  o Measurement techniques, e.g. for the parallel throughput on a =20
single host
  o Performance evaluation of virtualized packet switching technologies
  o Middleware for virtualization
- Performance issues of bandwidth and resource virtualization techniques
  o Media access mechanisms for network virtualization in wireline and =20=

wireless environments
  o Performance of Multiqueue Network Interfaces
  o Fairness among overlays using the same transmission system
  o Scheduling mechanisms for virtualized connections
  o Models for resource contention between virtual networks
- Performance issues of overlays for future network architectures
  o Performance of overlay composition
  o Performance assessment of grid computing platforms
  o Performance of content/data-oriented routing
  o Stability, robustness and resilience of overlays, virtual networks =20=

and self-organizing mechanisms
  o Static and time-dependent topology/resource/user models for overlays
  o Metrics for adaptation and dynamics in overlays
  o Mechanisms, Capabilities and Accuracy of Network Coordinate =20
Systems (NCS)
  o Traffic engineering for virtual networks
  o QoS and Quality-of-Experience (QoE) in overlays
- Performance of virtualized transport mechanisms
  o Performance of multi-source download
  o Path selection, path splicing in overlays
  o Engineering for path combination
- Performance of virtualized services and virtualized applications
  o Traffic models of virtualized services and applications (e.g. =20
w.r.t. QoE)
  o Performance of security mechanisms in virtualized network =20
environments
  o Performance of virtualization technologies for Grid Computing and =20=

Service Oriented Architecture (SOA)
o Performance of Virtual Storages
- Virtual Test Labs and Network Federation
  o Capability and performance and of network emulation
  o Performance of virtual network management mechanisms

I'm confused about this - that metric would kill nearly every current

Subject: Re: [nvrg-bof] poll on charter focus - RESPONSES DUE OCT 23

Hi Thomas,

I'm inclined to agree with your view below.

In particular, my understanding is the IRTF is supposed to work on topics t=
hat are pre-standardization but at some point will transition to IETF for s=
tandardization. Not on general networking (or even broader, systems) resear=
ch.

Now, I have a fairly narrow view of what topics are appropriate for success=
ful standardization (by which I mean that the work is not just standardized=
 but actually deployed). This view comes from having spent something like 1=
0 years in IETF, mostly doing interesting technical work that has seen litt=
le deployment. When I look at cloud computing and network virtualization, a=
s you say, there is a lot of activity going on in this area, including in i=
ndustry forums that are doing "standardized" APIs and such for cloud. Most =
of this activity is around systems that *are* actually getting deployed. I =
have a difficult time seeing where IETF could contribute.

One area that comes to mind, which I brought up about a year back, is a sta=
ndardized control framework for service deployment on virtualized systems. =
GENI is working on 5 (I think) such frameworks, all based on Web services. =
I believe their plan is to at some point select one or a collection of thes=
e. There are also a couple of FP7 EU projects currently being planned that =
have control frameworks as part of their work. So I could see us ending up =
somewhere down the line with multiple such frameworks, and an RG could be a=
 place to do an assessment and make a recommendation to IETF about what to =
standardize. The important point here is that the work on actually developi=
ng the frameworks is going on outside IETF.

However, I don't think that this topic is enough to form an RG. It could be=
 handled by a WG at the time the need for a standard became apparent.

Another topic is "over the top" v.s. "close to the metal" network virtualiz=
ation. Talking to GENI researchers, they seem to be planning to run virtual=
ized networks as overlays like X-Bone was. This is in contrast to the, shal=
l we say, "original promise" of virtualized networks, which is that they pr=
ovide isolation between traffic on different "slices". Providing isolation =
while still providing the cost benefits of statistical multiplexing, especi=
ally across service providers, is a challenging research problem. Most L2 V=
PNs with service guarantees are expensive and time consuming to provision a=
nd confined to a single provider, which is probably why academic researcher=
s aren't planning on using them. And statistical multiplexing is not possib=

Sure, but AFAIK they mainly concentrate on OS virtualization and not
on *network* virtualization.

See above.

Well, every time we try to get forward motion, we get feedback or input
that dissipates it, IMO. ;-)

For virtual networking, IMO there is work on virtualizing routers (ala
RFC1812), but not hosts (e.g., RFC1122/23).

For virtual systems, I'll let others speak as to the potential overlap
with other WGs or RGs.

Finally, this would be a RG (IRTF) not a WG (IETF).

Somehow I'm between both views :-)
I think that the RG should mainly focus on virtualization of networks,
but we should also include further aspects as mentioned in b).
IMHO we shouldn't concentrate on OS virtualization (as also Joe
pointed out, there is overlap with other groups in the Cloud/Grid
computing area), but aspects of network virtualization inside hosts
are definitely interesting, e.g., attachment to a multitude of different
VNets or storage in case of content centric networking. So, currently I
have to abstain since neither a) nor b) are a perfect fit for me.

 Roland

Let me be a bit of a naysayer here about this entire effort. This list
was set up more than a year ago, and still seems to be in the earliest
stages of figuring out what, if anything to do. That is not a good sign...

Meanwhile, virtualization (and cloud computing) continues to be a very
hot topic in many places, including:

  - DMTF (OVF, Virtualization Management Forum)
  - OGF Open Cloud Computing Interface WG (OCCI-WG)

Not to mention all the work various vendors are doing.

It seems to me like this group is pretty detached from all the related
work that is going on, and based on the pace of progress so far,
doesn't really have a critical mass to do anything.

What am I missing?

(I'm not necessarily opposed to a WG being formed, but I don't see the
point in bothering if the group isn't actually going to produce
anything useful...)

Hi,

I must have missed the note.
I favor focusing on virtual networks, since IRTF and IETF are related.
IETF doesn't seem to focus much on hosts, services, storage, and
sensors, but does focus on on-the-wire protocols.

Hi, all,

Work on updating the charter proposal hasn't progressed since the last
meeting in Stockholm. Aaron and I exchanged some ideas a month ago, and
Aaron asked for people to voice their position above then. I haven't
heard any discussion.

In order for this group to move forward, we need to decide what our
focus is. So, to that end, I'll summarize the current views:

	a) virtualization of networks
		Joe

	b) virtualization of systems,
	incl. networks, hosts, services, storage, sensors/actuators
		Aaron

Can everyone on this list please try to post a short not indicating your
view of where this group should focus ASAP, no later than Friday Oct 23.
That should help us gauge how to proceed.

Thanks,

Joe (just as a list member)
