Focus on a Premium Mobile User Experience
What is left for the service provider to differentiate themselves from their competition? It is the user experience. Since the playing field has been leveled for mobile devices, the most important thing carriers can do is focus on the user experience to create loyalty and drive revenue. Security is a big part of this picture.

What Operators Still Need in Next-Generation Transport
What do operators still need in next generation transport? This article will provide an in-depth look at what operators still need for next generation transport, and Packet Optical Transport Systems (P-OTS) in particular. P-OTS, thought well intentioned, has its weaknesses – and its early promises fell short of its expectations. We will discuss and focus on each of the challenges that exist in early P-OTS implementations by operators. Based on an assessment of these unique challenges, operators and vendors alike are gaining a better picture of what they really need, so that the full benefits of P-OTS can be realized

It's Time for Mobile-specific Encryption Policies
Imagine for a moment an attacker has gotten his hands on one of your employees’ smartphones. Perhaps it was forgotten in the backseat of a taxi or fell on the floor of a train on the way home from work. The attacker is able to get past the phone’s screen lock and password – 1234 wasn’t too hard to guess. Here's a look at things to consider when implementing encryption for mobile devices.

Resilient Synchronous Gigabit Ethernet for True 4G Mobile Backhaul Networks
A true 4G Ethernet mobile backhaul network must meet three fundamental design requirements – resiliency that provides five 9’s availability, synchronization of real-time services and low-latency, line-rate performance. Here's a look at packet ring resiliency.

Cloud Holds the Key to Success For Telecom
By delivering cloud-based services that are managed by a third party, telecommunication companies put themselves in an excellent position to become more competitive and comprehensive in their offerings. Compared to other competitors in cloud services, telecommunication providers bring important assets to the table. Their networks and long-term relationships with their customers in the communications environment have provided them with a great deal of knowledge about their customers' information technology. Combining that knowledge with a service offering to match their needs would give a telecommunication provider an offering unique among its competitors.

Packet Transport Evolution Strategies: Which Offers the Lowest TCO?
When it comes to network transformation to converged packet-optical transport networks, it is not a matter of if; it is only an issue of when. But what about “how”? There are many different approaches to the evolving network, from an MSPP evolution strategy all the way to a complete CESR overlay network. What makes the most sense for various key scenarios? This article outlines those strategies, those scenarios and, most importantly, the relative total cost of ownership for each.

Wi-Fi: a Partial Panacea for What Ails the Industry?
Offloading traffic from a 3G to a Wi-Fi network -- a.k.a load balancing -- is proving to be a less expensive way to relieve data overload while also delivering a better user experience. And, while 4G networks will offer some relief, those networks too will quickly become saturated. Frankly, there are just too many high-bandwidth applications available today -- and even more coming to market on an almost daily basis -- that can possibly be supported by even the fastest cellular networks.

Staying Competitive By Managing Services, Not Just Circuits
The challenge facing metro network planners is to find the most cost-effective way to deliver profitable services in the near-term while deploying a network flexible enough to support an array of new services in the future. Here's a quick look at MPLS, VPLS, and metro Ethernet Transport.

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.

Carbon Neutral Networks -- The ICT Sector Goes Green
The ICT sector, as one of the world's leading business sectors, has a global responsibility to ensure that its networks are carbon neutral. One of the ways by which a carbon-neutral environment can be achieved is by utilizing multi-service platforms, rather than single-purpose equipment in the network.

Thinking Broadly About Broadband Stimulus
The new broadband stimulus package provides important opportunities for people in unserved and underserved areas to reap the many benefits of high-quality broadband services. The question on everyone's mind, of course, is how to make best use of the $7.2 billion in funds that will be committed to broadband projects over the next 18 months

Sustainable Mobility: Strategies for Green Wireless
The evolution of mobility technologies has allowed us to do things faster, smarter, and cheaper. Mobility and wireless technologies increase employee productivity by virtualizing the collaborative experience. Employees can move between workspaces while remaining connected to their colleagues and information systems. Yet an often overlooked aspect of mobility is the benefit it brings in helping businesses reduce their carbon footprints.

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.

The Changing Market -- No Longer Business As Usual on the Testing Front
The network testing market is changing. Economic realities are forcing service providers and device manufacturers to work more efficiently together in the testing process in order to bring products to market faster and at lower cost.

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.
