Going Green by Reducing Watts: A Step by Step Guide
As an industry, we waste a ton of Watts and generate a lot of smoke to move packets around. By some estimates, IT comprised 2% of world’s emissions. While at first glance this figure might seem small, it is in fact on par with the CO2 produced by the airlines. Reducing Watts is an area that IT can get a handle on and one that can have the greatest amount of impact.

The Basis for Advanced Broadband Services: Deep Session Inspection
Most broadband facilities are used to carry a single service in which all packets are treated identically. This is consistent with the original "end-to-end" design philosophy of the Internet as well as more recent policy statements by regulators. But both the internet design philosophy and regulatory positioning reflect a world in which all applications are fundamentally similar in nature: data applications able to withstand packet loss and placing no demand on the network in terms of latency or latency variation. But this is no longer the world we live in. And this is where deep session inspection (DSI) comes into play.

The Future of Lawful Intercept
Imagine a group of criminals embarking on a crime spree throughout a city. Using mobile phones they coordinate their actions from miles away, sharing information to evade law enforcement agencies (LEA) and map out an escape route. But there’s a twist. The LEAs are well-coordinated as well, quickly securing a warrant to tap into the criminals’ wireless communications. In addition to listening in on their conversations and data transmissions by intercepting them, the law enforcement agency is able to precisely pinpoint the locations of the handsets sending and receiving the transmissions.

Next Generation Mobile Network Security: A Multi-layered Defense
As mobile devices evolve to resemble handheld computers more than traditional phones, it’s a safe assumption to make that soon the history of computer security will repeat itself in the mobile world. Swift proliferation of smartphones and open mobile device platforms/OS has posed new opportunities for malicious attacks. Mobile Core networks will soon be vulnerable to attack from the mobile user side, which has been a rare occurrence to date. This will require re-architecture the "first line" of security in the network. Additionally, massive increases in bandwidth from data services and increasing number of attacks on signaling and applications layers have proven to be difficult security challenges.

Optimizing Content Delivery in the Core with P2MP LSPs
Optimized content delivery has become a critical requirement due to the increased level of media-rich traffic on networks. These bandwidth intensive and quality-sensitive offerings raise scaling and operational challenges across multiple dimensions. They also require a mechanism complementary to VPNs to deliver content securely, with resiliency and with maximum cost-efficiency. Point-to-multipoint (P2MP) label switched paths (LSPs) can help.

Taking Care with Mobile Device Management
Mobile Device Management is going through a transition, from its roots in Firmware-over-the-Air (FOTA) for CDMA operators and GSM device configuration, to a foundation for a rich set of over-the-air customer care capabilities. The ROI for this new home of MDM in customer care, addressing a $25 billion annual problem, is proven, with the net result being lower operational expenses for the operator and increased customer satisfaction. Mobile Network Operators are facing challenges in delivering quality customer care, especially in the light of the explosive growth of smartphones.

Exclusive Home Theater Experiences Drive Customer Loyalty, Transcend Economy
For the first time ever, we saw HDTV shipments surpass standard TV shipments in 2008. Not only was this driven by price reduction for the hardware itself, but also by the increased availability of HD content, in part spurred by the efficient MPEG-4 standard that allows programmers and cable companies to deliver HD content in half the bandwidth of MPEG-2. How will these trends play out in the current economic climate?

Hardware Semaphores Ensure Smooth Sailing for Multicore Systems
While multicore processors come in several different flavors, like the general-purpose devices in PCs or the new multicore digital signal processors (DSP) that are found in advanced base station systems, all multicore processors raise certain design and architectural issues. One such issue that engineers consistently raise is how the multiple processing cores will share system resources such as input/output (IO) facilities, memory, and coprocessor capabilities while avoiding potential bottlenecks in system throughput.

Networking 2.0: Who's Managing the Next Generation?
By 2010, 20 homes will generate more traffic than the entire Internet did in 1995, according to the Internet Innovation Alliance. As that suggests, today's networking discussion is no longer about mere connectivity. Rather, in this age of YouTube, streaming radio, peer-to-peer (P2P) applications and other heavy consumers of bandwidth, it's about policy. Namely, what constitutes fair use of network resources and who sets those policies?

Maximizing Bandwidth, Minimizing Capex with DOCSIS 3.0 and an Integrated CMTS
The cable industry has talked about DOCSIS 3.0 for years, but the speed at which it's suddenly becoming a necessity is nothing short of breathtaking. While subscribers will soon look for increased upstream bandwidth, cable operators have a window of time where they can focus primarily on downstream throughput and take advantage of DOCSIS 3.0 technology that has now been commercially deployed.

The Time is Here for Fiber-based Communications
During the past several years, it has become clear that fiber-based communications driven by high-bandwidth Ethernet-based transport is the way of the future. As the adoption of Ethernet technology continues to rise, it is important to address the historical barriers to using fiber, including the lack of interoperability between carriers, the absence of fiber connectivity in the last mile, and the difficulty associated with bridging fiber and copper infrastructures.
