IWAN Wed: What’s more important? Uptime or Cost?

July 2, 2014 - 8 Comments

Screen Shot 2014-07-01 at 5.25.06 PM“Location, Location, Location” is what you need to keep in mind for real estate in the physical world.  But in today’s
enterprise environment where everything is virtual and many critical apps are in  the data center or cloud, the most important thing is connectivity.

So welcome to the era of connectivity, connectivity, connectivity!

As connectivity is so important, what can we do to ensure the uptime of the branch WAN connectivity without increasing costs?

As expected, Cisco has a great solution that is part of the Intelligent WAN or IWAN solution called Performance Routing or PfR. With PfR you can use dual line WAN connectivity in an Active-Active mode instead of the classic Active-Standby mode.

What does Active-Active mean?

Today in your branch you probably have one primary line (typically MPLS VPN) to your private Data Center and secondary line as backup. In most cases the backup line is not being utilized and it’s sitting quiet waiting for the main line to fail.

In an Active-Active scenario, the Integrated Services Router or ISR will monitor both WAN lines constantly and figure out automatically which line is best for each flow. Doing so will utilize both WAN lines and leverage the backup line that you are paying for anyway.

What does this mean for the business?

You dramatically increase the reliability of the branch connectivity and leverage any WAN technology to do so (MPLS, Internet, 3G/4G). That will give you the opportunity to reduce WAN costs while increasing or maintaining the reliability of the branch connectivity to the WAN.

So when you need to choose between uptime vs. cost, we at Cisco say “you can do both”.

  1. Thank you very much for this.

    • Thank you for reading it and comment on it

  2. Ido, this is a great demo! Thank you very much for this.

    • Thank you for taking the time to read it and comment

  3. Great demo, Ido.

    • Thank you :)

  4. This is a great demo of PfR within IWAN. But, one question, how is the AVC capability enabled and what kind of GUI is shown in the demo for QOS monitoring ? Is that a separate application license embedded in the IOS-AX bundle ?

    • Thank you for your questions. AVC is enabled through CLI or from GUI and it is part of the ISR-AX license bundle. LiveAction is the application we used in the demo for QoS monitoring (separate license has to be purchased for this app) hope it answer your questions Ido
