IMS, SIP and Circuit-to-Packet       Interview: NSN's Sue Spradley on LightSquared's Wholesale Mobile Data Paradigm LightSquared, a new company backed by Harbinger Capital Partners, plans to launch a wholesale-only, 4G-LTE network across the U.S. complemented by satellite coverage. LightSquared will provide wholesale wireless broadband capacity to a diverse group of customers, including retailers; wireline and wireless communication service providers; cable operators; device manufacturers; web players; content providers; and many others. NSN has been appointed vendor of choice in a deal valued at $7 billion over 8 years. Sue Spradley       Mobile Backhaul Transition Requires New Testing The move from TDM- to Ethernet-based transport does not come for free. TDM-circuits are well established at providing ultra-high reliability, voice quality of service, and accurate timing. Ethernet technology requires careful attention to match these capabilities. Testing for Ethernet-based mobile backhaul systems can be split neatly into performance testing and conformance testing. It is essential that wired and wireless components now be tested with the same types and scale of traffic seen in actual network deployments. Joe Zeto       Cybersecurity Requires Public/Private Coalition No longer is the task of cybersecurity relegated to IT offices and CIOs in the private sector, nor to a select number of government agencies. Instead, a call to action has been put forth to all entities -- especially the government -- to make cybersecurity a top priority. It is now recognized as one of the most important national security challenges of our time. Greg Oslan       A Rethinking of Cloud Services and Network Architecture The revenue potential of offering cloud hosting services is significant. To take advantage of this considerable opportunity, service providers must rethink both their network architectures and business models. Jim Theodoras       Delivering Scalable Video Solutions Advantages of SVC-Optimized QoS Scalable Video Coding is a layered video codec that is an extension of the established H.264 standard. SVC operates by transmitting a base video layer and one or more enhancement layers. Here's a look at how SVC helps solve the issue of poor quality and unusable desktop video conferencing due to packet loss. The long-term goal of this technology is to enable enterprises to deploy desktop video communications on a wide scale. Andy Singleton       Does Network Neutrality Impact DPI? FCC Chairman Genachowski's adoption of at a "Third Way" in regulating broadband traffic once again raises the question of what is proper network management. What is the likely impact for vendors of deep packet inspection (DPI) platforms? James Brear       Rethinking VPN Architecture at Layers 2 and 3 Since the earliest days of packet-based networking, there has been a debate between switched architectures (Ethernet/Layer 2 functionality, which dominate local area networks) versus routed architectures (IP/Layer 3 functionalit, which dominate wide area networks. This debate lives on when considering the use of MPLS technology in metro area networks for the delivery of enterprise VPN, residential triple-play and mobile backhauling services. Eylon Sorek       The SSL Encrypted Traffic Threat: Common Apps Pose Danger SSL has become the ubiquitous choice to secure web-based transactions. New cloud based and enterprise applications such as Salesforce.com, Exchange, SharePoint and most of the web-based email applications on the market such as Gmail and Yahoo, all use SSL to encrypt traffic. However, Intrusion Detection Systems (IDS) or Intrusion Prevention Systems (IPS) are essentially blind to SSL traffic. This is where the danger lies. Darrin Coulson       Backhaul and the National Broadband Plan The FCC's newly issued National Broadband Plan represents a sizeable "shift" toward supporting competition and making day-to-day broadband deployment tasks easier. Notably, the plan reconizes the role that backhaul plays in supporting end-user networks. Here is a look at key provisions impacting the backhaul. Joseph M. Sandri, Jr.       Femtocells and LTE Symbiosis Both LTE and Femtocells have received much attention in the industry press. While LTE has been accepted as the undisputed future of macro wireless networks, Femtocells have been seen as the technology that will help service providers address critical issues such as coverage and capacity. Moreover, while both technologies have received support and commitments from major service providers, the question of commercial uptake and return-on-investment still looms large in the minds of many service providers. How do they fit together? Sanket S. Nesargi       LTE -- What Voice Services? LTE is almost here. Service Providers are faced with the decision of whether to also offer LTE voice services in order to better utilize the new network infrastructure, or deploy LTE data-only networks. For the most part, it seems that the desire is there to transition to LTE voice sooner rather than later. But how will LTE voice be delivered? Jose Deras       Rethinking Access/Backhaul to Minimize Costs and Maximize Opportunity Cell phone users are inhaling bandwidth as fast as service providers can offer mobile broadband services. Let's examine some of the access/backhaul options that have been available to mobile operators for shouldering all of this cellular backhaul. M. Vijay Raman       Shedding Light on the Dark Cyber World Part II  As the 21st century criminal has moved into realms and dimensions never before dreamed of by yesterday's cop on the beat, law enforcement agencies are in hot pursuit. The vast reach of the Internet continues to shrink the world - there are more than 200 million Internet users in the United States alone - increasing the likelihood that you or someone you know will become a victim of cyber crime. There are certain steps to be made before we can successfully combat cyber crime.

With soaring demand for its wide range of enterprise connectivity services, Carrier Ethernet is among the great success stories of the decade. In the current economic climate, the logic of migrating to better, more scalable and cost-effective Carrier Ethernet services remains more valid than ever. Carrier Ethernet is now getting ready to also become the network interconnect solution of choice, allowing for ubiquitous, global Ethernet services. David Jack       Wi-Fi: The Better, Smarter, Faster Network Ours is a society requiring instant gratification: We want what we want, when we want it (usually right now). This attitude is reflected in the trend toward smartphones. In an increasingly mobile and connected society, we simply expect to be able to access email, Facebook or Youtube videos from our phones. Wi-Fi should be the preferred network for accessing this rich content whenever available. David Fraser       New Metrics Offer Better Ways to Map Energy Consumption As global climate negotiations continue in 2009, society faces a huge challenge to reduce carbon dioxide (CO2) emissions by 2050 -- a daunting task considering the world economy is expected to triple over the next 40 years. There's no question that carriers around the world will play a key role in the growth of the economy. But what of the power required to drive these networks? Jeff Baher       Increasing ARPU by Scaling Mobile Data Services Across the globe, consumer demand for value-added data services is creating both opportunities and challenges for mobile network operators. What is needed is the capability to deliver more sophisticated, targeted data applications that increase their revenue streams. This means operators need to intelligently manage both the volume of data traffic and the use of their applications to maximize the efficiency and productivity of their networks. John Clowers       Ethernet Evolution: E-NNI and Global Interconnect While other data services have languished during the recent economic downturn, Ethernet growth rates have ranged from 20 percent to 30 percent and sometimes more. Internet access, transparent LAN, Ethernet private line and Wholesale Ethernet have all grown substantially over the past several years and are forecast to continue growing rapidly for the foreseeable future.
