IMS, SIP and Circuit-to-Packet       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. Fred Ellefson       Enabling Fast and Seamless Global Connectivity With soaring demand for its wide range of enterprise connectivity services, Carrier Ethernet is among the great success stories of the decade.

Carrier Ethernet is now getting ready to also become the network interconnect solution of choice, allowing for ubiquitous, global Ethernet services. Nan Chen       Service Broker Network Elements: Bridging the "Converging Network" Growing competition from"over-the-top" non-traditional telecom providers, deregulation, rapidly changing technologies and saturation in some markets are making it increasingly difficult for operators to build market share and shore up their ARPU. While the NGN/IMS blueprint has provided a good foundation on which new feature rich applications can be built, the revenue generating, table-stakes applications of the legacy network are often overlooked. Ronald Gruia       Greening the Carrier Access Network with WDM-PON In times of stagnating subscriber numbers and flatrate-based price competition, carriers are finding it increasingly difficult to offset the rising costs of their network operation. The recent hikes in energy prices and increasing labor costs have added another element of complexity and urgency to the problem. Service providers are seeking to respond to this pressure by adopting greener and more energy-efficient networking strategies. Until now, this has often resulted in increased expenditures but this is set to change. Jim Theodoras       The Virtual Machine Tsunami We are facing a pending tsunami of VMs unleashed by an unprecedented liquidity in system capacity which is enabled by hypervisor-based cloud computing. This is being driven by corporate IT departments that are under greater capital spending constraints as well as by the high friction processes for getting applications into production using the legacy approach -- i.e. provisioning servers with a general purpose OS and then attempting to install/configure the app to work on the production implementation which is no doubt different than the development environment. Billy Marshall       What the US Election Means for Telecoms The accepted wisdom appears to be that the chairman of the FCC, Kevin Martin, will step down following the election of Barack Obama, and will likely be replaced by a Democrat nominated by the incoming president. What's next for telecoms? Jan Dawson       The Unique Promise of WDM-PON The drive toward carrier-class Ethernet rolls on, with the introduction of the External Network-to-Network Interface (E-NNI). E-NNI is the latest milestone on the road toward delivering carrier-class Ethernet services and is critical to delivery of ubiquitous services. Here is an overview. Paul Morkel       Could Mobile Voting Happen in 2012? or 2016? With long lines expected at polling places for today's U.S. election, many young American voters may be wondering today "Couldn't I have voted via my iPhone, Blackberry or other smartphone?" David Aviv       E-NNI Delivers Another Milestone for Carrier-Class Ethernet The drive toward carrier-class Ethernet rolls on, with the introduction of the External Network-to-Network Interface (E-NNI). E-NNI is the latest milestone on the road toward delivering carrier-class Ethernet services and is critical to delivery of ubiquitous services. Here is an overview. Jim Theodoras       Cyber Security: Protection Against Cyberwarfare Cyberwarfare has been a long time coming, and it will soon affect a computer near you. It goes far beyond the type of college-hijinks hacking seen just a year ago. This phenomenon occurs in a parallel virtual world, and is essentially the "New Cold War." Instead of seeking protection against physical armies using guns and bullets, institutions must guard against virtual armies whose weapons of choice are worms and viruses. With so much of our world’s economy dependent upon the Internet to function, cyberwarfare is a very real threat that merits close attention to cyber security. Antonio Nucci       Real-Time Traffic Intelligence for Defending Networks in an Age of CyberWar Managing and securing large IP networks has become nothing short of a nightmare for network operators due to their increasing complexity. Defending against a gamut of innovative and sophisticated network attacks and the prospect of cyberwarfare add to the complexity, making it harder for operators to effectively deliver value-added services to increase business revenue. Here are some strategic thoughts. Antonio Nucci [1/7] Send us your response to this article. Learn How to Get Your Column Published on this Site
