Software-Defined Networking will be a critical enabler of the Internet of Things

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach. Organizations are excited about the business value of the data that will be generated by the Internet of Things (IoT). But there’s less discussion about how to manage the devices that will make up the network, secure the data they generate and analyze it quickly enough to deliver the insights businesses need. Software defined networking (SDN) can help meet these needs. By virtualizing network components and services, they can rapidly and automatically reconfigure network devices, reroute traffic and apply authentication and access rules. All this can help speed and secure data delivery, and improve network management, for even the most remote devices.To read this article in full or to leave a comment, please click here

Cisco partners prepare for Cisco Live

With Cisco Live fast approaching, many third-party vendors who rely on Cisco and its installed base for their own business are announcing products before and at the show.

Ahead of the Cisco Live curve: Avi Networks announces Cisco ACI integration

Next week Cisco holds its annual user conference, Cisco Live, in San Diego. Cisco Live is a great show for customers to get educated on the latest and greatest Cisco technology available to them and how it can fit into their environment. Another benefit of Cisco Live is that customers can find technology partners that have developed solutions that work in conjunction with Cisco solutions.One vendor that jumped the gun and announced a solution early is the application delivery controller start up Avi Networks. I actually wrote about Avi earlier this year in this blog. I'm guessing that Avi Networks wanted to get ahead of the flurry of press releases that I'm expecting next week, and I'm glad they did as this seems like a compelling solution.To read this article in full or to leave a comment, please click here

Research community looks to SDN to help distribute data from the Large Hadron Collider

When the Large Hadron Collider (LHC) starts back up in June, the data collected and distributed worldwide for research will surpass the 200 petabytes exchanged among LHC sites the last time the collider was operational. Network challenges at this scale are different from what enterprises typically confront, but Harvey Newman, Professor of Physics at Caltech, who has been a leader in global scale networking and computing for the high energy physics community for the last 30 years, and Julian Bunn, Principal Computational Scientist at Caltech, hope to introduce a technology to this rarified environment that enterprises are also now contemplating:  Software Defined Networking (SDN).  Network World Editor in Chief John Dix recently sat down with Newman and Bunn to get a glimpse inside the demanding world of research networks and the promise of SDN.To read this article in full or to leave a comment, please click here

Open source meets telecom at NFV World Congress

When Linux first became a serious challenger for enterprise-class infrastructure, traditional IT vendors had to contend and to rationalize just what exactly this open source thing was. The initial response from many vendors was to attempt to stop it, but it only grew. And as open source grew, many mostly younger businesses learned to leverage it for great commercial success; however, the titans of the previous era have had challenges adapting their business models to embrace open source successfully.To read this article in full or to leave a comment, please click here

Digging Deeper into the Cisco ASA Firewall REST API

Security orchestration methods and of course SDN is driving the need for programmable interfaces in  security products.  The Cisco ASA Firewall added a REST API back in December with the 9.3(2) code release.  I've asked Mason Harris, from Cisco, to write up a quick how-to primer on the ASA API capabilities.  Thank you Mason for the great information.Author: Mason Harris CCIE #5916Solutions Architect, Global EnterpriseOver the years I’ve seen many different custom methods used to manage ASA firewalls. Most of them involve some version of command line interface (CLI) scripting since nearly all ASA features and functions are available in this manner. Perl and Expect scripts are the common scripting languages in use today for managing ASAs.To read this article in full or to leave a comment, please click here
