OPEN: A Fundamental Part of the Network of the Future

Over the past several years, I’ve been lucky enough to be a part of two important trends in the networking industry -- the evolution of open standards and open APIs, and the definition of policy as the key interface to the network.

Open is an extremely important word to the future of networking. The simple dictionary definition for open means not closed or locked, allowing access to inside, and freely accessible.

The ultimate networking environment will allow a user the freedom to connect anything together in the cloud and to an existing environment. In order for this vision to happen, companies must work together to create a common language.

OpenStack has garnered a lot of interest in the development community and among our customers.  We at Cisco have been actively helping to shape the discussion around policy.  Working collaboratively with our partners and competitors, we helped create Group-Based Policy (GBP), an intent-driven policy API for OpenStack.

The Group-Based Policy initiative represents a significant innovation in how users conceive, manage, deploy, and scale their applications in OpenStack clouds.  And its now available as a 100% open source solution available to any vendor.  When coupled with Cisco Application Centric Infrastructure, we are able to offer our customers a completely policy-driven network.

ONE + ONE = 6: New Math for Enterprise Programmability

In my previous 3-part blog series I discussed the challenges in the Enterprise WAN and relevancy of SDN in overcoming these challenges and how Cisco ONE Enterprise Networks Architecture addresses these WAN challenges. In this blog post I will discuss how Cisco ONE (Open Network Environment) and ONE Enterprise Networks Architecture fit together. In a following blog, I will discuss how Cisco ONE Enterprise Networks Architecture provides six significant benefits to enterprises through programmability. ONE + ONE = 6 is the new math for Enterprise programmability!

Cisco ONE

Cisco ONE (Open Network Environment)

Cisco ONE is a comprehensive, Cisco wide solution (not just data center) approach to making networks more open, programmable, and application-aware. There are numerous blogs, and videos about Cisco ONE that can be found here. As a brief summary, Cisco ONE comprises of 3 pillars that provide a programmable approach to both physical and virtual infrastructure: Read More »

Let’s Clear Up Some Misconceptions – Is SDN Relevant to the Enterprise WAN?

June is summer weather in the San Francisco Bay Area, but quite different from the June I was used to in Boston. A common misconception around Mark Twain and his relationship with San Francisco summer is that he never said “The coldest winter I ever spent was a summer in San Francisco.” But he did say: “Cold! If the thermometer had been an inch longer we’d all have frozen to death.”

June is always exciting here and in Europe. NBA playoffs are on and the Giro d’Italia just ended with the Italian Vincenzo Nibali winning it emphatically. The San Antonio Spurs have been so good but King James brought the Heat back from a certain death in Game 6. Game 7 decides it all!

Equally exciting is the buzz in networking circles, especially in the Bay Area, around Software Defined Networking (SDN) and how it is potentially commoditizing networking infrastructure. However, just as we cleared up that misconception about Mark Twain, I’d like to clear up some points around WAN challenges with cloud migration and how SDN might be applied to overcome these challenges.

In this blog post I will discuss the challenges in the Enterprise WAN and relevancy of SDN in overcoming these challenges.  In part 2, I’ll cover how the Cisco ONE Enterprise Networks Architecture addresses these WAN challenges. Read More »
