With Windows Server 2012, System Center 2012 SP1, and our hardware and software partners, we have a complete end-to-end SDN solution that provides rich manageability, scalability, and flexibility for these cloud networks. Our solution works on existing networks, so customers can realize the benefits of SDN today. At the same time, our approach allows partners to enlighten their network software and network equipment to participate in, support, and augment the multi-tenant data center brought about by Hyper-V Network Virtualization. Our open approach, focus on standards, and our close partnerships across the industry make our solution particularly unique and compelling for customers.

In many ways, VMware’s acquisition of Nicira is a late acknowledgement of the importance of SDN as a critical enabler for the cloud. However, I think our approach is substantially more mature, delivers end-to-end capability, and provides an open platform for partners to innovate. Most important, our implementation is available broadly for customers to begin deploying today.

Our solution is built on a standards based tunneling technology called Network Virtualization General Router Encapsulation (NVGRE) built on the IETF standard GRE protocol. We are building an entire eco-system around Hyper-V Network Virtualization with

  • Silicon partners like Intel, Emulex and Broadcom building specialized network cards to support NVGRE traffic.
  • Switch extension partners like inMon and 5NINE building extensions
  • F5 Networks, IvoNetworks and nAppliance building devices for cross-premise connectivity
