How Virtualization Helps Break Down the Barriers of Wi-Fi

by Angela Whiteford Angela Whiteford No Comments

While the industry is already discussing plans for 5G, the future of wireless carrier services probably looks a lot more like your existing (and admittedly less exciting) Wi-Fi router. The reality is that 4G/5G is ideal when you’re on the move, but not so much when you’re sitting in a chair indoors—which is what most of us are doing, most of the time. No wonder then that Wi-Fi has quickly (if quietly) become the wireless network of choice for enterprises and consumers. In the U.S., 60% of all mobile data consumed by smartphones and tablets is currently carried over a Wi-Fi network. In Europe, that number is even higher, at 78%.

Why are subscribers choosing Wi-Fi? It’s cheaper (because it’s “off-network”) and it works better indoors, where 3G/4G signals are often weak. But Wi-Fi also lacks the quality/security of a true 4G experience, creating an opportunity for fixed and mobile network operators to provide a carrier-class Wi-Fi experience by integrating Wi-Fi connectivity into their core networks—and, yes, generate revenue from Wi-Fi services in the process. The challenge, as with most network transformations, is how to do this quickly, seamlessly and cost-effectively. The answer is virtualization.

 

The Benefits of Wi-Fi Network Virtualization

At Affirmed, we have enabled fixed and mobile operators to rapidly deploy a complete, secure Wi-Fi gateway solution—Trusted WLAN Access Gateway/Proxy (TWAG/TWAP) and evolved Packet Data Gateway (ePDG)—on consolidated, commercial off-the-shelf (COTS) hardware. This drives down cost and complexity because it reduces the number of boxes in the network, and it allows network operators to quickly deploy a complete, proven and centralized solution that can be easily scaled across geographies.

We’ve taken the concept of consolidation even further by adding virtualized Value-Added Services (VAS) to our solution so that network operators can rapidly create and seamlessly orchestrate services over Wi-Fi networks to enhance the subscriber experience. Network operators, including one of North America’s largest cable providers, are already using our solution to deliver Voice over Wi-Fi and Wi-Fi roaming services.

One of the biggest barriers to bringing Wi-Fi into the core network is the issue of scalability. This comes to the fore when dealing with untrusted Wi-Fi networks, which require a high number of IPsec-encrypted sessions that can quickly test the limits of a physical gateway. Affirmed has solved this problem with a highly scalable, virtual ePDG solution that can increase the number of IPsec-encrypted sessions on-demand by dynamically and intelligently shifting processing resources in real-time without requiring additional hardware. As a result, fixed and mobile network operators can confidently bring Wi-Fi services into their LTE networks and deliver a seamless, high-quality experience over any wireless network.

All of us at Affirmed Networks are incredibly honored to have been included in Forbes’ recent list outlining the “the Next Billion Dollar Start-Ups,” a compilation that is available on line and will be featured in the company’s print edition in May.

According to Karsten Strauss of Forbes, to create the list Forbes went “in search of young companies with enough momentum to reach the upper echelon and comprise the next-generation of unicorns.”

With more than 23 customers, and increasing interest from mobile operators worldwide, we feel confident that Affirmed Networks meets this criteria, and we are honored to be in included along with the other deserving companies highlighted by Forbes.

As part of this process, Forbes surveyed more than 90 VC firms, asking for nominations of their “most promising” start-ups, and the ones “most likely to reach sky-high valuations.”

In addition to thanking Forbes for recognizing us, we would also like to thank our dedicated and passionate employees, and our growing list of customers who have given us the opportunity to lead them through an evolution of their networks.

NFV Tipping Point: China Mobile Outlines Phased Approach for NFV

by Angela Whiteford Angela Whiteford No Comments

As we have previously shared, Affirmed Networks continues to experience significant traction with Tier 1 operators worldwide. This is reflective by our 20+ customers, our more than 40 trials, and by the strong interest we saw at Mobile World Congress 2015 as operators now fully realize that the adoption is not a “if” but a “when.” There is no doubt, the NFV tipping point is upon us.angela-headshot

More evidence was highlighted in a recent report authored by China Mobile, the leading mobile services provider in Mainland China. With the world’s largest mobile network, and more than 800 million subscribers (also a world record), China Mobile is not just big, they have always been viewed as one of the most innovative operators in the industry. This focus on innovation was highlighted recently as the company provided a glimpse into how they view their ultimate deployment of NFV. Specifically, China Mobile outlined a unique, three-phased approach for deploying NFV in an end-to-end architecture across their mobile network.

As the graphic below indicates, China Mobile’s phased view for NFV spans the short-term, mid-term and long-term and spans all aspects of their network. As part of this view, China Mobile also outlined a list of vendors that it views as having the potential to support their innovative approach. We are very proud to report, that Affirmed Networks was included in this list – one of the few emerging players in a list of the usual suspects (legacy equipment providers). While this should not be viewed as a formal vendor selection, we are excited to be included and view it as yet another strong acknowledgement from the industry that supports what we all believe – that Affirmed Networks is the company that will lead the evolution and virtualization of today’s mobile network. To quote Malcolm Gladwell*, we believe that NFV has reached that “magic moment” and is about to “spread like wildfire.”

As China Mobile’s view supports, the tipping point has crossed the threshold.

Don’t Wait and See on NFV for EPC

by Angela Whiteford Angela Whiteford No Comments

For years we have been hearing about how virtualization has revolutionized the enterprise data center, providing a wide range of benefits from both a business and technology standpoint. With the advent of network function angela-headshotvirtualization, the movement has moved to the mobile network, allowing the virtualization of network functions into a connected network capable of delivering communications services on top of industry-standard, high-volume servers. This shift promises to offer a host of benefits over the legacy, proprietary hardware that has been the foundation of our communications networks for decades.

Far from a fad, NFV and the software-defined network are getting serious consideration from tier-one operators globally. Case in point: In December, AT&T announced its intent to virtualize and control as much as 75% of its customer-facing network with software by 2020. They see the shift as one that will allow them to significantly reduce capital expenditures while at the same time increase the capacity of their network.

For those of us in the industry, this should come as no surprise. We have seen mobile operators face a variety of challenges, one of the most critical from a business perspective being the declining average revenue per user. This is being exacerbated by the trend of exponential data growth which is forcing operators to continue to add capacity to their networks.

The time to buck conventional wisdom is now
In order to add this capacity, while conventional wisdom might suggest we do more of the same – build bigger boxes that can handle more data, and deploy more of them – now is the time for a new way of thinking.

Legacy mobile data architectures just aren’t economically suited for today’s world of rapid data growth and smart devices. In fact, the “bigger box” approach isn’t just economically irresponsible, it flies in the face of Moore’s Law from a technical perspective, as the commoditization of boxes just can’t keep pace with the traffic growth.

By continuing to attempt to solve the problem with legacy approaches, operators are adding fuel to the fire; spending money for a short-term fix that will soon need addressed again as traffic growth continues. As opposed to “throwing dollars and boxes” at the capacity problem, customers that adopt NFV have the ability to add capacity as part of a step-by-step approach that is as much a benefit to their subscribers as it is to their shareholders.

The ability to adjust to changing traffic patterns dynamically will become increasingly important with the emergence of machine-to-machine communications and the impact it will have on operator networks. Vodafone predicts that by 2020, networks will need to support more than 50 billion connected devices. While we are just beginning to understand how it will impact networks, what we do know is it will involve many connections, with a very low average revenue per user, and the traffic patterns are expected to be “bursty” in nature. As a result, many experts believe that running M2M on a virtualized network that enables them to “dial up and down capacity” will be critical as the impact of M2M becomes more widely understood.

An architecture based on NFV dramatically changes the economics of networks, bringing tremendous service flexibility in a manner that nicely coexists with legacy network investments. Through the virtualization of network functions onto existing data center infrastructure operators can transform the economics of deploying and scaling mobile networks from a capital and operational perspective. What’s more, the benefits aren’t just economic, as this software-driven approach also simplifies the operation of the network, which significantly decreases the length of time required to launch the new service offerings required to create the new revenue streams needed for profitability.
