SANTA CLARA -- AT&T is considering offering bare metal switches and servers to consumers as customer premises equipment for the carrier’s services.
At the Open Network Summit conference here, Andre Fuetsch, AT&T senior vice president, Architecture & Design, said the economics of commodity bare metal switching, as well as the scale, performance and programmability, make it appealing for the carrier to sell into the customer premises.

Cisco’s enterprise SDN controller is still in controlled release a year after it was first supposed to be generally available and months after an updated GA date. The APIC Enterprise Module shipped in February in controlled release to “multiple” customers who are using it in production, Cisco says, including IBM, which is using it on behalf of German airliner Lufthansa.To read this article in full or to leave a comment, please click here
SAN DIEGO -- Cisco is out to prove it has an SDN for everyone.At its Cisco Live conference, the company unveiled offerings to drive programmability across its product line to address the requirements of enterprises, service providers and mega-scale data centers.The additions are to Cisco Application Centric Infrastructure (ACI), Border Gateway Protocol (BGP) EVPN and NX-OS programmable network options. ACI is targeted at the mass market – commercial, enterprise and public sector customers – while BGP EVPN is aimed at service providers and programmable NX-OS at mega-scale data centers.To read this article in full or to leave a comment, please click here
As Senior Director of Technical Marketing and Solutions Engineering at Cisco, Frank D’Agostino leads the development and technical go-to-market strategy for Cisco’s Application Centric Infrastructure (ACI), the company’s portfolio of Software Defined Networking tools. Network World Editor in Chief John Dix recently spoke with D’Agostino about what the company is learning as customers adopt SDN. (D’Agostino was formerly VP of WW Technical Operations for Nicira Networks, the company VMware bought to drive its SDN strategy.)
Is there a profile emerging of what a typical ACI customer looks like in terms of the types of challenges they’re trying to address?To read this article in full or to leave a comment, please click here
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
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. Two are start-ups Glue Networks, a developer of SDN software for Cisco router WANs, and Avi Networks, a maker of application delivery controller software.To read this article in full or to leave a comment, please click here
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
HP this week signed a definitive agreement to acquire ConteXtream, a provider of OpenDaylight-based SDNs for service providers.Terms of the deal were not disclosed.ConteXtream develops an SDN controller for Network Functions Virtualization (NFV), software-based services that replace hardware-dependent Layer 4-7 functions, like load balancing and firewalls. ConteXtream’s products enable carriers to use existing standard server hardware to virtualize functions and services for subscribers, and to chain services across servers and subscribers.To read this article in full or to leave a comment, please click here
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

Alcatel-Lucent this week extended its carrier SDN product line with an automation and network control system designed to accelerate service provisioning from multivendor IP and optical infrastructure.The company’s Network Services Platform combines Alcatel-Lucent’s SDN-based software with its 5260 service-aware management system, Service Router operating system and the 1830 Photonic Service Switch GMPLS routing engine algorithms from Bell Labs. It also has a REST API interface to the Nuage Networks Virtual Services Platform SDN controller for data center networks so the IP/MPLS/optical network can be quickly provisioned based on the needs of data center interconnection and virtual machine mobility.To read this article in full or to leave a comment, please click here
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
This column is available in a weekly newsletter called IT Best Practices. Click here to subscribe. Many vendors are racing to compete in the burgeoning software-defined WAN space. Each competitor has its own strategy of how to implement the network overlay that makes the network connections, provides virtualized services and steers applications. It all comes down to what the SD-WAN vendor wants to help its customers achieve.VeloCloud has an entry in this race, and the company has two goals: to simplify the way companies set up their branches within their wide area network, and to improve the performance of the WAN. There are several specific problem areas VeloCloud is setting out to address.To read this article in full or to leave a comment, please click here

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
