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. Regards, Hideki Okita >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 > >-- >Anna Fischer >HP Labs >-- >Hewlett-Packard Limited registered Office: Cain Road, Bracknell, Berks RG12 1HN.
