Securing the Open Network Environment

With all of the focus on Software Defined Networking, open networking, API’s, you name it, I do often wonder how, with all of this ‘openness’, does an Enterprise keep their network secure? After years of security teams working  tirelessly to protect their business critical infrastructure does this paradigm shift where anyone can write an application to control, get the intelligence from, and manipulate the network become the reason for many a sleepless night for security experts around the world? And on the other hand, can this new way to manage the network help in threat detection and prevention?

If you, like me, are wondering the same thing, I invite you to register here for the 5th session of the Cisco Open Network Environment Webcast Series titled “Securing the Open Network Environment” broadcasting on July 30th at 9 a.m. PST.

Jon Oltsik, ESG, Security, Mike Nielsen, Bret Hartman, ONE, SDN

Join Mike Nielsen and Bret Hartman from Cisco as well as Jon Oltsik from Enterprise Strategy Group (ESG) for a great discussion featuring live Q&A throughout the session.

If you have missed any of our previous sessions featuring introductions to OpenFlow, OpenStack, Cisco’s onePK, and Using Open Source in Networked Environments, please visit www.cisco.com/go/onewebcasts.

The Programmable Network: Elastic Services

In our last blog on “Advanced Flow Control” we used the metaphor of a three-dimensional collection of intersecting highways of many different kinds with a wide array of vehicles carrying various types of passengers to represent the Internet of Everything­ (IoE).  The IoE concept has come a long way since it was first coined by the Auto-ID Center. Today the concept has broadened into a catch all for current and future network-connected endpoints, from smart meters to vending machines, security cameras, all forms of transportation, and consumer electronics ─ not to mention PCs, tablets, and smartphones. People with electronic tags will one day be connected to the IoE to monitor their health. Many dogs and cats already have chips for location tracking. The opportunity for new services will be unlimited and customers will expect instant access to networking resources to launch, alter, or eliminate those services.

Cisco at Hadoop Summit 2013

At this year’s Hadoop Summit 2013, I presented on the “The Data Center and Hadoop” which built upon the past two years of testing the effects of Hadoop on the data center infrastructure. What makes Hadoop an important framework to study in the data center is that it contains a distributed system that combines both a distributed file system (HDFS) along with an execution framework (Map/Reduce). Further it builds upon itself and can provide other real-time or key/value stores(HBASE) along with many other possibilities. Each comes with its own set of infrastructure requirements that include throughput sensitive components along with latency sensitive components. Further in the Data Center,  understanding how all these components work together is key to optimized deployments.

After studying many of these components and their effects, the very data we were alanyzing became a topic of a lot of our discussions. We combined application performance data, application logs, compute data AND network data to build a complete picture of what is happening in the data center.

With the advent of programmable networks (aka “Software Defined Networking”) it is not only important to make the network more application aware, but to also know where and how to analyze and make the right connections between the application and the network.

Cisco ONE Enterprise Networks Architecture: Programmability for WAN 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:

Enterprise Networks: Practical Differences in LAN and WAN SDN Deployments

In my last blog I introduced challenges Enterprises are facing in their WAN deployments and the definition of ONF SDN. While the broad definition of ONF’s SDN architecture implies many theoretical answers to these challenges, we need to be pragmatic. Let’s take a look at the practical differences in LAN and WAN networks that affect how you’d deploy SDN on each.  Read More »
