Transform Service Provider Architectures to Support Virtualized Managed Business Services

Cisco estimates over 50 billion new devices will be connected to the Internet by 2020.  To support the Internet of Everything, service providers must undergo an infrastructure transformation.  The network needs to become more open, programmable, automated, adaptive, and agile.  To guide this transformation, the Cisco open network strategy for service providers is depicted as three interwoven layers:  the Evolved Programmable Network (physical and virtual network Infrastructure), the Evolved Services Platform (for orchestration of resources) and Applications and Services layer to enable virtualized services such as Cloud VPN and Security.  With these three layers working together, providers can begin to realize the benefits of an open network that is readily open to new devices, open for quickly enabling new services, and open to endless possibilities.

Last week, Cisco announced two Read More »

What is the Cisco Customer Solutions Architecture (CSA) Layered Approach?

This is part 2 of the “Your Business Powered By Cisco Customer Solutions Architecture (CSA)” blog series.

CSA Description

The following figure shows a simplified view of the Cisco CSA. It has five horizontal layers: Physical Infrastructure layer, Virtualized Infrastructure layer, Services layer, Service Management and Automation layer, and App/portal layer.  Supporting each layer from top-to-bottom, there are three vertical layers: ITSM/ITIL services layer services enablement, Security layer for providing security across each of the horizontal layers, and Cisco Intellectual and domain management layer for providing Cisco best practices at each of the horizontal layers.

This CSA is a logically layered architecture (LLA), with each layer providing a distinct function.   The model is designed in a hierarchical fashion with devices and facilities at the bottom, customer interactions at the top, and various required functionalities in the middle layers.  The key to this model is the abstraction of each layer into software-defined components with standardized interfaces. Similar to other LLA models such as ITU-T TMN (Telecommunications Management Network), each horizontal layer supports the layer above in performing its business functions.

CSA Layered Approach

The interaction between various layers is through abstraction, orchestration, and API’s.  The customers’ requests are processed from the top layer where orchestration fulfills the various components and provisions into the infrastructure using the API’s between the layers.  Similarly, the Read More »

Join Us at BBWF 2014

Network functions virtualization (NFV) and Software Defined Networking (SDN) will get a lot of interest this year at BBWF 2014 Broadband World Forum 2014 as carriers seek to make networks more agile and efficient. In talking to both service providers and large enterprises, it’s clear that we are already in another major transition in the networking industry.

I’ve spoken with many talented individuals about what NFV and SDN means to their networks.  Some of these visions are very broad and long ranging and some are more narrowly focused on delivering or optimizing a single service very quickly.  It’s clear that NFV has already been deployed in many different service applications while SDN has been noticeably slower to develop a focused following.  Even in the case of Virtualized Network Functions (VNFs), there is an interesting combination of features focused on services delivery and features focused on infrastructure innovation.  In this case “services” are typically the services that carriers sell to their end customers such as a  Virtual Private Network (VPN)  and “infrastructure” is the virtualization of the typical network functions such as a virtualized route reflector on an x86 based server instead of running the route reflector application in an existing (physical) router.

Does Virtualization Really Matter?

That was the question that an attendee at a recent conference sponsored by the Communications Technology Management, part of University of California’s Marshall School of Business, asked me last week.  With all of the industry discussion on the topic over the last year or two on the topic, I think it is always worthwhile to pause, assess, and reflect, as sometimes some of the simplest questions can be some of the hardest.

“Yes,” I told him, “but maybe not how you think.”

No question I’m proud of the advances Cisco has made in this area, from our announcement of the Evolved Services Platform in February to now having over 40 virtualized functions in our portfolio.  As far as we can tell, it is the largest, most expansive virtualized portfolio in the industry with so much of it not on a drawing board but already in use in customer network.

But while we’re proud of the aggressive execution of our strategy, far more relevant than the number of functions, however, is what they can enable.  I think this was the reason for the question and certainly the reason for my answer.
Take our announcement last week: enabling Read More »

Launching Passpoint Connectivity Deep in the Heart of Texas

ROB KALMBACH PHOTOGRAPHYThis is a customer perspective guest blog contributed by Dr. Derek Peterson, Boingo Wireless Chief Technology Officer.

In early 2014, Boingo made the bold move of launching Passpoint-enabled Wi-Fi at 26 airports throughout the U.S. and Brazil, bringing seamless, secure and instant Wi-Fi access to travelers with Passpoint-ready devices.

In partnership with Cisco, the Boingo team worked to launch Passpoint first in high-traffic locations serving tech savvy audiences hungry for a better way to connect. We found an ideal Passpoint pioneer deep in the heart of Texas: Austin-Bergstrom International Airport (ABIA), a long-time Boingo network partner.

The Austin airport has always been a technology trailblazer, focused on improving the customer experience by leveraging the best in new technologies and services. The airport was the first to offer Wi-Fi to passengers in 2000, and has since worked with Boingo to upgrade the network to meet today’s traveler connectivity needs.

ABIA is also serving an increasingly tech-savvy community. Austin is the gateway to one of the fastest growing culture and technology hubs in the United States, and has become a go-to spot for start-ups and tech companies. The city becomes the heart of the tech world every year for the South by Southwest festival, and the airport serves more passengers than ever before year-round, marking their first Read More »
