The New Network

Understandably, there are lots of questions about what this New Network looks like. This month I’ll share what the architecture of the New Network is and the key pieces required in making it a reality.

From Connectivity to Content

As new network applications are introduced almost on a daily basis, Internet traffic is continuing to grow. While you would think this is a good thing for service providers, the opposite is actually true. As I mentioned in my last blog, there is a symbiotic but unhappy relationship between content providers with compelling applications (which drive customers to the network), and the network ...

The New Service Provider

Not too long ago, if I asked you to think of service providers, names like AT&T, British Telecom, Deutsche Telecom, would have come easily to mind. Today, your response would not be so predictable. In the last few years, we have witnessed not only explosive growth in the amount of traffic on the Internet, but also in the types of applications running over it. This has created an opportunity ...

Another Broadband Divide?

The period for the first round of applications for the National Broadband Stimulus funds ended on Aug. 14. And while it likely won’t be known for a while who will receive funding and how much, we can be sure of one thing: There will be a lot of controversy around these funds. The plan, originally proposed by Obama during his campaign for presidency, is intended to bring broadband to ...

Unwired

iPhone 3G. Palm Pre. Blackberry Bold. Blackberry Storm. Nokia Surge. Google G1. The number of “smart” phones popping up in the market is increasing rapidly. A mobile phone is no longer only about making calls; now we use them to browse the Web, take pictures, record video, scope out traffic on the highway, send text messages, trade stocks — and just about any other activity ...

The Wait Is (Almost) Over

As the 100 gigabit Ethernet IEEE standards are being finalized, networking vendors and service providers are gearing up for tests and demonstrations of this latest evolution of Ethernet. It has been a long wait: The transition from 10 gigabit Ethernet to 100 gigabit Ethernet has been one of the longest the networking industry has seen. Previous technology iterations happened much quicker: 100mbps ...

Running Networks Hot: Urban Myth or Viable Strategy?

In my previous blog, I mentioned the trend of running networks hotter in order to squeeze more performance out of the existing assets, delaying capacity upgrades until absolutely necessary. This discussion is not new; it is revisited every time the economy slows down. Network traffic keeps growing in spite of — or perhaps because of — the downturns, and while increasing the ...

Exaflood. Or not?

The current economic environment has raised many questions about what the future holds for the telecommunications and Internet industries. While no one disputes that Internet traffic continues to grow in spite of — or perhaps because of — the macroeconomic downturn, many have questioned whether service providers will continue to invest in their networks, or whether they will simply ...

Virtualize and Conquer

Virtualization is rapidly gaining traction in the networking world because it offers the promise of increased flexibility and scalability, while lowering the overall cost of ownership. As a general concept, “virtualization” refers to the transformation of discrete hardware resources supporting individual processes into abstract resources that serve a multitude of processes, which may ...

Cloud Computing and the Consumer

By Juniper Networks' Ashwin KrishnanA few trends seem to have hit home that have made me sit up and take notice that there is a seismic shift under way in cloud computing for the consumer. Let me first talk about three instances of this and then dwell on the larger implications.I was alerted about lala.com a few weeks ago and since then the way I listen to music has changed dramatically. In ...
