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.

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.

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.

Delivering Scalable Video Solutions <br><i> Advantages of SVC-Optimized QoS</i>
|
|
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.

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?

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.
