As part of SDNCentral’s ongoing efforts to bring you more SDN/NFV use cases, we bring you a series of free webinars from NEC, featuring Ivan Pepelnjak of ipSpace. Be sure to check the webinar series landing page for newly released videos.
Today’s data center networks contain more devices than ever before – servers, network equipment, storage systems, security appliances – many of which are further divided into virtual machines and virtual networks. OpenStack Networking manages these complex, next-gen networks in a scalable and automated way, but the newest version is not without its own challenges when it comes to actual implementation.
In this video, noted networking expert Ivan Pepelnjak of ipSpace.net outlines how OpenStack Networking fits within the OpenStack architecture and the challenges posed by the latest release. He also shares how administrators can use NEC’s ProgrammableFlow SDN to overcome those obstacles.
Code named Neutron, formerly Quantum, OpenStack Networking is a pluggable, API-driven system for managing networks and IP addresses. Neutron was designed to accommodate a wide range of plugins to handle integration with other networking services, relying on plugins supplied either through the OpenStack distribution or by outside vendors.
Unfortunately, Pepelnjak says, most Openstack deployments use a single Neutron plugin, increasing reliance on vendor plugins. And vendors, in turn, must reinvent their hardware and software to control their switches as well as the hypervisor.
While the vendor solutions are enough to implement the core Neutron functionality of Layer 2 segments and ports, they typically cannot implement the latest Neutron extensions or additions that perform functions including Layer 3 networking, static routing, security groups, and load balancing. Pepelnjak explains in the video how administrators can use ProgrammableFlow, a production-grade commercial implementation of OpenFlow, to create virtual tenant networks in OpenStack and use it to control both physical and virtual switches.

The webinar is part of a series of free webinars from NEC covering typical OpenFlow-based SDN use cases using NEC’s ProgrammableFlow. Upcoming webinars in the series will cover SDN use cases including network monitoring. Check them out on the webinar landing page.
