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.

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.

Location, Location, Location: <br>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.
