Enterprise Networks

In my last two blogs I discussed the challenges Enterprises are facing for their WAN, the differences between Enterprise needs in their LAN and WAN, and how the traditional ONF model for SDN isn’t practical for the Enterprise WAN.  Let’s now look at how the new Cisco ONE Enterprise Architecture can address this.

Cisco ONE Enterprise Network Architecture

The new Cisco ONE Enterprise Networks Architecture based on Cisco Open Network Environment (ONE) was introduced at InterOp Las Vegas during Rob Soderbery’s keynote, with a deeper dive in a blog by Inbar Lasser-Raab  (shown in Figure 2). Briefly, the 3 layers are similar to SDN Architecture but are also vastly different in the following ways:

How Cisco ONE Enterprise Networks Architecture enhances Enterprise WAN programmability?

Cisco ONE Enterprise Networks Architecture brings the networks and applications closer together across the entire Enterprise network. It is all about creating a feedback loop between the applications and the network and allowing the applications to control the network at many levels. Cisco ONE Enterprise Networks Architecture provides the tools to make the Enterprise network programmable both in data-centers (LANs) and at distributed sites (WANs). This is true and effective openness of enterprise wide networks that increases the speed of the deployments of new services and applications. Through open APIs at each layer and deep access to network resources through programmability, Cisco ONE Enterprise Networks Architecture creates the mutual awareness of networks and applications. This mutual awareness helps enterprises overcome the WAN challenges.

What’s next:

In the next few blogs I’ll cover additional aspects of SDN and Cisco ONE Architecture.

Thanks for reading and please comment on any and all aspects. I look forward to your comments. Stay tuned for the next blog post.
