Innovate in Your Network

OpenFlow enables networks to evolve, by giving a remote controller the power to modify the behavior of network devices, through a well-defined "forwarding instruction set". The growing OpenFlow ecosystem now includes routers, switches, virtual switches, and access points from a range of vendors.


The Open Networking Foundation (ONF) is now the home of the OpenFlow specification. We invite you to join the ONF and be part of the exciting standardization and commercial development and deployment of OpenFlow.

HP OpenFlow capable firmware is now GA

December 7th, 2011 by Masa

OpenFlow capable firmware for HP switches is now available without requiring special license. It can be downloaded by customers/partners from HP’s website.

Current version is K.15.05.5001(for OpenFlow researchers only) as Early Availability and here is how I downloaded it:

  1. Go to
  2. You will be required to sign-in to download the firmware. If you have your account, go to the next step. Otherwise, create it now and come back. To crate your account, place the mouse pointer over the “Sign-in” link on top right corner. Another menu pops up and click “Create new account” and follow the instruction.
  3. In Auto Search text-box, type the part of the product name (e.g., 5400 or 6600)
  4. Select appropriate product (check the check box)
  5. Click “Display Selected” button
  6. Click “software downloads” link (a bit hard to find.. look for light-blue link on the right side)
  7. Find the proper firmware and click the link shown as “>>”. As of the timing of this blog post, “K.15.05.5001 (for OpenFlow researchers only)” in Early Availability is the one.
  8. You’re required to sign-in. Click “Sign-in with HP Passport” button.
  9. Sign-in
  10. Finally. Click “Download” button (Read the SUPPORT CAUTION first).

IBM announced 10 gigabit ethernet OpenFlow switch G8264, which has 48 × 10 GbE SFP+ ports and 4 × 40 GbE QSFP+ ports. It was demonstrated at Interop Las Vegas in May and now it is available as a product with GA. The switch runs in either of two modes, traditional L2/L3 mode or OpenFlow mode (the mode is chosen at the switch boot time). In OpenFlow mode, the switch supports up to 97,750 flows. Here is a link that lists the major features of the switch. More information at
