Rest API


In this video, David demonstrates the use of a simple bash script to update flow table entries on OpenFlow switches using the RESTful API and the HP VAN SDN Controller. The HP Controller supports both Java and RESTful northbound APIs. The southbound API protocol used in this example is OpenFlow 1.0.


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 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 […]
