Re: [nvrg-bof] virtual network management information model



Hi all,
I'd like to bring to the attention of the group the
work ongoing in the FEDERICA project co-funded by the
European commission.

It is a Europe wide infrastructure made of circuits and
system, both capable of virtualization, capable of
offering virtual infrastructures (almost clean-slate)
to researchers.

More information in http://www.fp7-federica.eu/

We are willing to participate to the effort in
the wg.

The interest is in particular in virtualization in all network
and system layers HW, becoming a common "substrate".

Kind regards			Mauro Campanella

Yes, VEPA is targeting exactly this. It helps unifying the management of virtualized data center networks by simplifying the interface between a virtualized server and the data center network infrastructure. The introduction of embedded virtual switching within the hypervisor introduces visibiltiy and control issues as traditional network devices no longer process certain packet flows. VEPA addresses these challenges.

We have also submitted patches to the Linux kernel to enable basic VEPA operation for the Linux bridge module:

http://www.mail-archive.com/bridge at lists.linux-foundation.org/msg01249.html

We also submitted VEPA patches for Xen/KVM virtualization layers.

Let me know if you have any specific question, or if you are interested in anything particular around VEPA.

Cheers,
Anna

Anna,


Thank you for the information about EVB and VEPA.

We are interested in these active works around server
virtualization platforms since it would become
a configuration and management interface between
the data center network management system and a
server virtualization platform.

I thought you might find this interesting too - related to unified
virtual network management within data centers and increased management
complexity introduced by traditional virtual switches:
http://tech.groups.yahoo.com/group/evb/

An unofficial Edge Virtual Bridging ad hoc group that is working to
develop concepts and proposals related to Edge Virtual Bridging for
consideration by the IEEE 802.1 working group. The proposal(s) are
intended to address the following needs: (1) a simple aggregation
capability that could be integrated into new NICs to support PCI
virtual functions and PCIe IO virtualization devices, (2) to allow an
external bridge control of vNIC connectivity, and (3) to support the
creation of simplified, stand-alone network edge devices. The focus of
this group is primarily oriented at the Data Center environment.
Most importantly the proposal of the VEPA standard:
http://www.ieee802.org/1/files/public/docs2009/new-hudson-
vepa_seminar-20090514d.pdf
A Virtual Ethernet Port Aggregator (VEPA) is a capability within a
physical end station that collaborates with an adjacent, external
bridge to provide bridging support between multiple virtual end
stations and external networks. The VEPA collaborates by forwarding all
station-originated frames to the adjacent bridge for frame processing
and frame relay (including 'hairpin' forwarding) and by steering and
replicating frames received from the VEPA uplink to the appropriate
destinations.
May be implemented in software or in conjunction with embedded
hardware.
Let me know if you have any questions.

Regards,
Anna
