When we talk about the impact of Cloud Computing we shouldn’t forget what it’s named after, although I’ve always thought “water vapor” and not “ash.”
I’m sure by now you’ve probably heard or seen the pictures on the news of the volcanic eruption in Iceland affecting global commerce and air travel, especially in Europe. Cisco has been affected in multiple ways, including employees stranded and meetings cancelled. Over the last few days I’ve been contacted by friends and colleagues unexpectedly unable to return home from various places around the world. While the Icelandic ash grounds the planes we’re also seeing a huge spike in demand for some cloud based collaboration tools – such as Webex and TelePresence, all the while increasing the load on the Internet.
The theme at this year’s CTIA conference was Mobile Life. As I walked the floor of the exhibition hall, it became apparent that mobile enablement is permeating many of our day-to-day experiences.
Whereas the mobile industry has focused on device innovation over the past two years, a shift toward application innovation has now taken hold. Device innovation remains strong, but manufacturers and carriers now realize the degree to which applications can drive users to adopt mobile data and rapidly increase their usage.
Nearly every carrier and handset manufacturer is talking about creating application stores and fostering application ecosystems. There is also a growing realization that linking or federating such applications stores could lead to increased value creation for all the participants. Machine-to-machine (M2M) is also gaining momentum, and CXOs of carriers are talking about connecting “billions of devices.”

It’s an exciting time to be in the rapidly changing telecommunications industry. The growth in video, mobile, and cloud services represent compelling industry trends that will shape the market in Transport and Routing for decades. Winners and losers in the business might be determined based on the architectural choices made in the near future. However, as a busy executive or analyst we know that you don’t have the time to spend two days out of the office learning how we believe the network will evolve and what your colleagues in the industry are doing in the face of change. Therefore, we’re pleased to bring the expertise directly to your desktop. At Cisco’s NGN Virtual Summit – we’re looking to cover the dual transformational aspects of NGN: transport and IP services evolutions.
If you are responsible for network services, you face multiple challenges:
Video over IP: In a few years, the volume of video traffic will dwarf any other type of traffic on the network. Video head ends are becoming more like data centers which will create a large scale one-to-many distribution network.
Mobility: Smart phones have enjoyed rapid adoption in the marketplace. They are bringing the power of Internet to a huge user base, anytime, anywhere. Is your mobile infrastructure ready for this transformation?
Cloud Computing: IT departments seek to host applications in the service provider or cloud provider facilities. This trend is motivated by a clear cost benefit to IT departments. This also means that remote data centers will attract more traffic from the subscriber base and virtualization of machines will dramatically increase the DC-to-DC communications requirements.
The above will pressure the transport network and that’s what we will explore at the Cisco NGN Virtual Summit. For example:
The TDM infrastructure is under stress because it’s not optimized for data. There is a steady appetite for larger and higher capacity L2VPNs and Private Lines. A tsunami of data traffic is forming and the existing SONET/SDH infrastructure can’t cope. The transport infrastructure must evolve and adapt to these new demands.
The need to support yet increase the profitability of transport services such as basic WAN connectivity during the transition period to all IP over Ethernet.
Cisco recognizes that the challenges for the Next Generation Networks won’t be met by a single technology or group of people. Multiple organizations and people will be involved to pursue the same goal, using complementary technologies in different areas of the network. Network transformation has to be looked at different layers, from the application down to the photonic. How do we optimize video distribution, how do we prepare for DC interconnect, how optical and packets meet, how do we make the best use of the fiber infrastructure we have in the ground? These questions are related.
Consider: From now on, just about every video title created, whether for episodic television, advertising, theatrical, home theater, or short-form Internet viewing, needs to be formatted in multiple ways, so as to suit the requirements of the native viewing environment. Watching an episode of “Lost,” for instance, or any other TV show, plays differently on a handheld, than it does on a big-screen TV.
These multi-formatting requirements also extend to the looming 3DTV viewing environments. Watching Avatar in the theater, for instance, carries different resolution and distribution requirements than watching it on home TV. Plus, 3DTV adds some spin to the challenge because of the extra bandwidth associated with what’s essentially a two-camera/two-eye content creation methodology.
That’s why we at Cisco are so focused on what we call the “IP contribution and distribution” part of the video life-cycle. It’s all about making it easy for content owners and service providers to compress, process and distribute their video products, in formats that can be consumed on lots of different viewing surfaces.
Not that long ago, the notion of sending “contribution-grade” video over an IP network was considered unlikely, at best. Packet sizes were too big and unwieldy, people thought, not to mention the “special needs” of video, relative to other data types.
“Contribution-grade” is a broadcast video engineering term meaning “highest possible quality” – not unlike a digital master. When content owners prepare video shows and events for distribution, for instance, they want at the onset the cleanest, highest-grade product because it inevitably gets manipulated and re-processed along the way.
Because contribution-grade video typically connotes an uncompressed, lossless stream, it wasn’t immediately obvious that an IP network could handle it.
That’s all changing, now. In large part, it’s because contemporary media distribution involves carriage of multiple file formats, sizes, and resolutions, all of which are in a constant state of change. IP allows media distributors to deal with multiple content types, so as to provision and dispatch them quickly.
