IPAM is Essential to Network Management

By Tim Rooney, Director, Product Management, BT Diamond IP

The discipline of network management has long offered technical and business benefits to organizations with the centralization of the monitoring, control, and provisioning of distributed network elements such as routers and application or services databases. These benefits include holistic management of a network from a centralized point where appropriate resources can be leveraged for troubleshooting, resolution, and escalation. The centralized “top down” approach also lends itself well to supporting structured network change control procedures.

It’s a small leap to consider DNS and DHCP servers as network elements in need of network management within an IP network, as they provide critical enabling services to clients or subscribers. While not in-band or on the data path for user IP traffic like traditional network elements, DNS and DHCP servers provide foundational services required to make such in-band data paths possible and usable, including automated IP address assignment and simpler IP application navigation.

But one cannot manage Read More »

Cisco’s TV Technology Footprint Spans Nearly 300 Million Homes

chowj-300x400By Joe Chow, VP & GM, Connected Devices Business Unit, Cisco

Headsup: Worldwide, Cisco’s TV technologies are present in nearly 300 million homes. Three. Hundred. Million. Homes! As my kids would say: Get. Out! That means that nearly a quarter of the homes on planet Earth are watching TV powered by Cisco – pretty amazing, right?

For us, it’s a very big deal, because it makes us the market share leader in set-top boxes. It took a long time to get here. We’re very happy, and grateful, to the 150 service providers and media companies who chose us for the television services they deliver.

One of the reasons for the introduction of the set-top box, dating back to the analog boxes of yore, is to secure television programming from theft. On the condition that you’re a subscriber, you get access to multichannel video. That, and channel expansion beyond channel three (which was as high as early television sets could go) gave Read More »

How the World’s Most Advanced Network Processor is Making the Internet of Everything Possible

Over the last 30 years the Internet has transformed multiple times. Most of us take it for granted these days. We expect to watch videos on Netflix, run our meetings over WebEx, talk to our friends across the globe on Skype, and have access whether we’re at work, home, or on the go. But we forget that the Internet wasn’t originally built for this – it’s been barely 20 years since email, the World Wide Web, and always-on network access have become realities. The changes have occurred at a dizzying pace.

In the beginning the only way to handle the work of the Internet – routing and forwarding packets – was by using general-purpose computer chips. This didn’t last long as the explosive growth in network bandwidth drove Cisco and other infrastructure providers to use more customized silicon. Indeed, Cisco’s market success was driven in large part by our ability to offer industry-leading solutions with the best combination of price, performance, and capabilities. This in turn was fueled by Cisco’s use of internally developed network silicon using advanced ASIC development models ahead of competitors who continued to rely on general purpose CPUs or FPGAs to power their products.

Now the Internet is on Read More »

The Top Six Things to Ask a Prospective DRM Provider

With over 25 years’ experience in content protection and over 250M VideoGuard secured devices, we at Cisco know a thing or two about security. We are harnessing this knowledge to further develop VideoGuard DRM, an open, comprehensive solution built to meet the Pay TV provider’s unique needs.

For that reason, we’ve compiled our Top Six List of Things To Ask a Prospective DRM Provider.

  1. Is it capable of multi-platform protection? Some solutions may protect video on IP-based screens, like tablets, laptops and smart phones. Others may protect video running on traditional digital set-tops, built for QAM/MPEG-2 transport. The ideal solution bridges legacy and new, offering integrated security and seamless cross-device experience.
  2. How widely is it deployed? If so, ask for details. To how many client devices and on Read More »

The Programmable Network: IP and Optical Convergence

Someday soon, personal sensors, wearable gadgets, and embedded devices and services may make today’s PCs, laptops, tablets, and smartphones look quaint by comparison. But as the Internet of Everything­ (IoE) ─ with its diverse array of devices accessing a plethora of existing and new services ─ continues to rapidly evolve, user friendly interfaces mask growing complexity within networks. An article on today’s digital designers in the September 2013 issue of Wired captured how the focus is now “creating not products or interfaces but experiences, a million invisible transactions” and that “even as our devices have individually gotten simpler, the cumulative complexity of all of them is increasing.”

Which inevitably takes us behind the curtain to the exciting challenge of building hyper-efficient programmable networks using virtualization, the cloud, Software Defined Networking (SDN), and other technologies, architectures, and standards.

So far, this blog series on The Programmable Network has described various new and exciting capabilities leading to greater efficiencies and cost benefits. We’ve shared with you how you can now:

  • Visualize and control traffic using path computation via a network controller
  • Monitor and optimize traffic flows across network connections
  • Order services through an easy-to-use online portal which then launches automated service creation tasks

These capabilities are all Read More »
