NEC Launches World's First Virtualization Mobile Core Network Solution

Bolstering NEC SDN Solutions' Lineup for the Telecom Carrier Market

Tokyo, Oct 22, 2013 - (JCN Newswire) - NEC Corporation (NEC; TSE: 6701) has begun sales to telecom carriers of the world's first(1) commercial virtualized Evolved Packet Core (vEPC), a virtualized mobile core network solution that achieves Network Functions Virtualization (NFV), network functions on a virtualization infrastructure running on a commercial-off-the-shelf server hardware with Intel Architecture(IA).

The solution will first be offered as one of NEC SDN Solutions'(2) Network Functions Virtualization Solutions for the telecom carrier market unveiled in July this year. Evolved Packet Core (EPC), the mobile core network accommodating LTE and other mobile access networks, is composed of functions such as Mobility Management Entity (MME), Serving Gateway (S-GW) and PDN gateway (P-GW).

NEC vEPC succeeded in virtualizing all of the functions on an IA server while achieving Carrier Grade Service quality and capabilities. As a result, this solution provides telecom carrier which includes TCO optimization, dynamic and quick network capacity scaling and management, and rapid launch of new services that deliver new revenue sources. Moreover, the use of a virtualization infrastructure makes it possible to dynamically boost server resources according to network traffic volume and service trends. Furthermore, the use of IA servers significantly reduces equipment costs and procurement lead time when compared to existing dedicated hardware for mobile core network products.

NEC has delivered the vEPC as part of a communication infrastructure development project in Myanmar, with the system scheduled to launch commercial operation in December this year.

Key features of the new product are outlined below.

1.Achieves efficient utilization and expandability of resources due to increased communication processing

NEC's vEPC employs the NFV concept of achieving various network functions through a virtualization infrastructure running on an IA server. This enables scaling out from a single server and achieves efficient resource utilization.

2.Achieves the high-performance and high-availability qualities that telecom carriers demand in a system, even in a virtualization environment

By applying Intel's Data Plane Development Kit (DPDK) and co-working with Intel for DPDK enhancement for virtualization, NEC's vEPC enables high-speed data plane processing in virtualization infrastructure on an IA server. Furthermore, the new vEPC enables the flexible configuration of system capacity between the control plane, which handles mobile service control based on its load status, and the user plane, which handles large amounts of data plane traffic on the same COTS IA server pool.

Also, by installing NEC's carrier grade hypervisor into the virtualization infrastructure, the vEPC realizes Carrier Grade services with the real-time performance, service stability and reliability that telecom carriers demand.

3.Achieves reduced TCO with the use of IA servers

By installing EPC functionality through a virtualization infrastructure running on an IA server, capital expenditures (CAPEX) are significantly reduced. In addition, the use of COTS IA servers enables operators to select the hardware for vEPC to build optimum virtualization systems among various virtual network and service functions. Also, an auto-healing function (automatic restoration) that utilizes virtualization technology while maintaining the reliability of dedicated hardware based EPCs, allows this vEPC to support additional reliability features that reduce operational costs (OPEX), such as eliminating the need for rushed replacements in the event of a hardware failure.

In recent years, telecom carriers' networks have become increasingly complex, and to introduce new communications equipment based on traffic demand, tasks such as designing new networks and procuring dedicated hardware have required a great deal of time and money. The issue of sharply rising operational costs associated with additional capital expenditures has also emerged. This solution addresses these issues.

With the aim of realizing a safe, secure, efficient, fair and prosperous society, NEC will continue to develop technologies, products and servers, forge alliances with partners, actively propose solutions to customers, further strengthen its ICT-based SDN business, help create new value for customers and contribute to the development of advanced social infrastructure.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability.

After you have your data under control, you can then analyze it in one place, saving time and resources.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now ...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible.

Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facin...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
