And the controller is the place to start. HP's Virtual Application Networks SDN Controller is an x86-based appliance or software that runs on an x86-based server. It supports OpenFlow, and is designed to create a centralized view of the network and automate network configuration of devices by eliminating thousands of manual CLI entries. It also provides APIs to third-party developers to integrate custom enterprise applications.
The controller can govern OpenFlow-enabled switches like the nine 3800 series rolled out this week, and the 16 unveiled earlier this year. Its southbound interface relays configuration instructions to switches with OpenFlow agents, while it's northbound representational state transfer interfaces -- developed by HP as the industry mulls standardization of these interfaces -- relays state information back to the controller and up to the SDN orchestration systems.
The controller also has exposed APIs so third-party software developers can write their own applications to it. HP has already written three: the Virtual Cloud Network application, Sentinel security and a distributed load balancing application co-developed with CERN.
The Virtual Cloud Networking application enables enterprises to configure a "self-service" VPN in a public cloud and control the introduction of new services and applications. It automates network provisioning but limits provisioning actions to low-risk infrastructure elements. It helps scale networks beyond the limits of traditional hardware, and supports the OpenStack API for public and private cloud orchestration.
The Sentinel security application automates network access control and intrusion prevention of OpenFlow-enabled switches. It is designed to provide real-time threat characterization and protection from more than 700,000 botnet, malware and spyware malicious sites, HP says. With this application, users can eliminate many dedicated security appliances, HP says.
The distributed load balancing application provides adaptive load balancing based on application feedback, HP says. It synchronizes load balancers for optimized traffic distribution and also eliminates the need for dedicated load balancing hardware, HP says.
HP says that even though it is "leveraging" OpenFlow in the switches and controller, there is nothing that would preclude the products from utilizing other elements of SDN and programmability. HP plans to eventually also support VXLAN and NVGRE as network virtualization overlays in its products, but Mayer and Gillai did not provide a time frame for doing so.
Last, HP rolled out an array of service to help enterprise implement HP SDNs. They include network provisioning baseline assessment and an SDN proof-of-concept service that reports provisioning time improvements achieved with HP Intelligent Management Center and Virtual Application Networks technologies.
The Virtual Application Networks SDN Controller is targeted for second half of 2013 availability. The Virtual Cloud Networks Application is also expected to be available in the second half of 2013.
The Sentinel security application is currently available as an early access program to select customers. OpenFlow support is currently available on HP switches as a software upgrade.
HP SDN services will be available in early 2013.
