Network virtualization is by no means a new concept for VMware. Think about it for a moment — wherever vSphere (or any other VMware T1 or T2 hypervisor) has been implemented, a virtual switch exists and connects guest VMs to the physical world. That’s more than 500,000 customers globally, millions of vSphere hosts, and many more millions of virtual network ports backed by a standard (vSwitch) or distributed virtual switch (dvSwitch). In fact, if you count the network ports provisioned by vSphere and logically assigned to VM nics, one can argue that VMware is one of the top datalink providers on earth. Okay, perhaps that’s a stretch, but you get my point! VMware virtual networks have existed just about as long as VMware itself. And since the very beginning, there has been no shortage of innovation. The vSwitch has evolved in many ways, leading to new technologies, increased scope and scale, distributed architectures, open protocol support, ecosystem integration, and massive adoption. Over the years VMware has continued to introduce new networking technologies through organic maturity and strategic acquisition — ESXi platform security, dvSwitch (and associated services), vShield, vCloud Networking and Security (vCNS), etc. — and leveraged 3rd party integration into partner solutions, such as Cisco’s Nexus 1000v (a solution brought to market by tight collaboration between VMware and Cisco).…
