How to Build Software Defined Networks Using Elastic Virtual Switches - Part 1

Guest Author
Oracle Solaris 11.2 enhances the existing,integrated software-defined networking (SDN) technologies provided by earlier releases of Oracle Solaris to provide much greater application agility without the added overhead of expensive network hardware.
It now enables application-driven, multitenant cloud virtual networking across a completely distributed set of systems; decoupling from the physical network infrastructure; and application-level network service-level agreements (SLAs)—all built in as part of the platform. Enhancements and new features include the following:
• Network virtualization with virtual network interface cards (VNICs), elastic virtual switches, virtual local area networks (VLANs), and virtual extensible VLANs (VXLANs)
• Network resource management and integrated, application- level quality of service (QoS) to enforce bandwidth limits on VNICs and traffic flows
• Cloud readiness, a core feature of the OpenStack distribution included in Oracle Solaris 11
• Tight integration with Oracle Solaris Zones
About the Elastic Virtual Switch Feature of Oracle Solaris
The Elastic Virtual Switch (EVS) feature provides a built-in distributed virtual network infrastructure that can be used to deploy and manage virtual switches that are spread across several compute nodes. These compute nodes are the physical machines that host virtual machines (VMs).
An elastic virtual switch is an entity that represents explicitly created virtual switches that belong to the same Layer 2 (L2) segment. An elastic virtual switch provides network connectivity between VMs connected to it from anywhere in the network.
For more information how-to combine software-defined networking (SDN) and Elastic Virtual Switch (EVS) technologies using examples see the following article:How to Build Software Defined Networks Using Elastic Virtual Switches - Part 1
