ScanSource is proud of our 99.87% shipping accuracy rate, along with our great customer service, depth of manufacturer offerings, and our value-adds. One of our most unique value-adds is our in-house key injection services. We made a significant investment in time and capital to become certified, which alone is a year-long process. As a result, resellers are pleasantly surprised to learn we are the only specialty technology distributor that is an Encryption Services Organization (ESO) and was certified in 2012.

The financial transaction business is evolving right before our eyes. Merchants will need to upgrade their POS hardware and software systems as the October deadline for the EMV liability shift is fast approaching. With this shift, new technology will be required to accept chip credit cards thus producing a large need for new equipment (and subsequent increase in revenue opportunity). [Read More…]

How will 5G ever become actualized if it requires CSPs to make sweeping changes to their legacy investments and infrastructure? Network Function Virtualization (NFV) and Software Defined Networking (SDN) are envisioned to facilitate the transition of the magnitude required by 5G. If we examine the basic benefit pillars that NFV and SDN claim to deliver, then it becomes clear how this paradigm is essential in the deployment of 5G networks.

So what are NFV and SDN? Simply speaking, Network Function Virtualization is a new networking architecture and framework that takes cloud-based concepts and applies them to telecommunications networks. In NFV, a network is comprised of software-based applications called Virtual Network Functions (VNF) that run in virtual machines or containers on standard Commercial-Off-The-Shelf hardware (e.g., servers, storage and networking devices). As shown below, NFV replaces the traditional purpose-built hardware-based network elements and moves that functionality to the cloud decoupling it from the underlying physical hardware.

Instead of CSPs purchasing purpose-built hardware platforms that perform explicit functions, NFV enables the provider to build a network infrastructure using cloud-based methods (i.e., SaaS, IaaS) to define network element functions. These virtualized applications are then linked together via a concept called “service chaining” to deliver end-to-end services automating a lot of the installation and provisioning functions that previously required manual intervention. You can read more about the benefits in SDx Central’s 2015 Network Functions Virtualization Report.

SDN enhances NFV by providing a controller capability, which consolidates network control (brains) of the packet forwarding function (muscle) and provides a centralized view of the distributed network for more efficient orchestration and automation of network services. Jointly SDN and NFV provide a framework that allows for network self-diagnostic and lifecycle management with minimal manual intervention. SDN and NFV are complementary approaches that offer a new way to design, deploy and manage telecom networks and its services. Networks based on NFV/SDN are inherently more flexible, programmable, scalable, and more efficient.

The ETSI NFV Industry specifications Group (ISG) has a working group (WG) that is explicitly commissioned to define an NFV architectural framework for functional virtualization of network functions; management and orchestration of network functions and services; and Business / Operations support interfaces for lifecycle supervision (i.e., FCAPS) . The diagram below shows a high-level component view of the major functional blocks of the architecture, the reference points and connections.

The goal of ETSI NFV WG is to define architecture, open APIs and reference points, leveraging open source proof of concept (PoC) projects and communities to drive open standards. These open standards are intended to enable 3rd party vendors to develop framework components that can collaborate with various vendor components so that CSPs are not restricted in selecting functional and management components. NFV will allow network operators to more efficiently use their resources based on the dynamic needs of their services. CSPs are able to achieve greater network configuration agility with respect to capacity scaling as well as integrating new functional elements to deliver new services.

The Open Network Forum (ONF) has defined requirements for SDN. It is actively collaborating with ETSI NFV WG and other organizations to ensure that specifications and requirements are aligned and with minimum overlap. ONF is defining its requirements for the SDN controllers using the OpenFlow protocol between network elements and SDN controller (i.e., southbound interface).

As the 5G frontier continues refinement, definition and specification over the next 5 to 10 years, it is apparent that the mobile network landscape will mandate a total facelift to address the demands of the new services, capacity loads, bandwidth targets, QoE (infinite Internet, RTT latency response), QoS (ubiquitous access, robustness, reliability) and scalability dynamics that are the underlying tracks leading to 5G. 5G ‘s characteristics include:

  • More connected devise (1000 x)
  • Higher subscriber densities (up to 12,000 devices per km^2)
  • Low latency (<1ms RTT)
  • Higher data rates (>10,000 Mbps)

This means 5G will require an infrastructure that is highly flexible, dense, fast, accessible, resource efficient and can scale as needed to meet the dynamic needs of the underlying network services. In order to get to that leading edge, it is with no uncertainty that this transition will not happen without the networking architecture of NFV and SDN. 5G will introduce a new lifestyle to the masses, and it will ride on the NFV-SDN train that is currently taking the CSP eco-system by storm.

Sending a Message About the Importance of Medication Adherence

by Jeremy Burton July 13, 2015 Business

By Tim Moynihan, Dialogic, Inc. Maybe the old physicians’ line should have gone, “Take one pill and call me in the morning.” That’s because nearly half of all patients don’t take their medication as prescribed, something known as medication nonadherence. It’s a growing problem for physicians and their patients, particularly for treatments such as HIV/AIDS […]

Adding Voice to Your Windows Apps Just Got Easier

by Jeremy Burton July 13, 2015 Business

By Tim Moynihan, Dialogic, Inc. There are millions of .NET developers out there, with more to come now that Microsoft has made .NET an open-source platform. Yet .NET developers with hands-on experience building voice-enabled applications can still be relatively hard to find. This presents a challenge to enterprises, especially as they look to wrap voice […]

WebRTC Cannot Escape the Codec Challenge of the Past: The Need to Transcode

by Jeremy Burton July 13, 2015 Business

By Tsahi Levent-Levi All the signs direct to a sad truth: transcoding will be an integral part of our WebRTC future. It started out nicely. The utopian idea that a single voice codec and a single video codec can rule it all in WebRTC: just have Opus and VP8 supported and all will be good […]

The Role of Media Servers in NG911 and e911

by Jeremy Burton July 13, 2015 Business

By Jim Machi, Dialogic, Inc. While we take for granted now that we can use text, video and data to communicate with each other, this is not yet the case for emergency communications. However, enhanced 911, or Next Generation 911, aims to enable emergency services to handle text, video or hi-def pictures, which is clearly […]

Twenty-First Century Fax

by Jeremy Burton July 7, 2015 Business

In the Doors song, “Twentieth Century Fox,” Jim Morrison begins with the line, “Well, she’s fashionably lean…” In a rare bit of prognosticating—could Jim Morrison be a poet and a prophet?—he might just as well have been singing about the twenty-first century fax. The popularity of the fax, like classic rock and roll, appears to […]
