OpenFlow: HP VAN SDN Controller and Mininet integration

This video demonstrates OpenFlow integration between the HP VAN SDN Controller and Mininet. The HP Controller is an SDN controller that supports OpenFlow version 1.0 and 1.3. Mininet allows for easy learning and testing of and OpenFlow network emulated on a PC. This is similar in concept to GNS3 or HP Simware.

Spanning Tree and OpenFlow

Questions I often get asked include: Can you run Spanning Tree and OpenFlow together? What happens when Spanning Tree blocks a port? What will OpenFlow do? Will not having redundant links in an OpenFlow network result in loops? Firstly, it is possible to run an OpenFlow network connected to the HP VAN SDN Controller with […]

OpenFlow configuration: HP Comware 5500 switches with the HP VAN SDN Controller

HP Comware switches have supported OpenFlow from late 2013 on HP 5900 switches running Comware7. OpenFlow is now also supported on A5500-EI switches running Comware 5.20 release R2221 as well as A5500-HI switches running Comware 5.2 release R5501. The release date for some of this the was last few days of December 2013. Click here […]

OpenFlow Datapath ID (DPID)

How are OpenFlow switches identified? Each OpenFlow instance on a switch is identified by a Datapath Identifier. This is a 64 bit number determined as follows according to the OpenFlow specification: “The datapath_id fleld uniquely identifies a datapath. The lower 48 bits are intended for the switch MAC address, while the top 16 bits are […]

OpenFlow on HP Comware switches

OpenFlow configuration: HP Comware 5900 switches with the HP VAN SDN Controller

In this blog entry I’ll show you how to get a basic OpenFlow network working using HP 5900 Comware switches and the HP VAN SDN Controller. HP announced support for OpenFlow on the Comware 5900 series switches towards the end of 2013. The 5900 switches support OpenFlow 1.3.1. These switches require Comware version 7.1 and […]

OpenFlow configuration HP ProVision switches with the HP VAN SDN Controller

OpenFlow configuration: HP ProCurve switches and the HP VAN SDN Controller

In this blog entry I’ll show you how to get a basic OpenFlow network working using HP ProVision switches (formally ProCurve and E-Series)  and the HP VAN SDN Controller. See this blog entry for the configuration of HP Comware switches. See other blog entries for more complicated topologies. This is a simple topology of two 3500yl switches […]

Mininet and the HP VAN SDN Controller

Mininet is a network emulator that can create and emulate an entire OpenFlow network locally on your PC. This is similar in concept to network emulators such as Simware (HP Comware) or GNS3 (Cisco IOS). Mininet allows you to create different topologies consisting of OpenFlow switches and hosts (end devices). Topologies can vary from a single […]
