One of the most interesting aspects of the Cisco Visual Networking Index is how the explosion of Internet traffic is taking place everywhere. We’ve talked before about how countries such as Iceland and Bermuda are leveraging high speed connections to the world to grow their economies. This time let’s look at Greece and competitive carrier hellas online (hol) on how they are preparing for the zettabyte era. (A zettabyte is 1021 bytes, in case you had forgotten).
Hol is one of the largest fixed-line telecommunications services providers in Greece offering a range of retail, business and wholesale services, and they also own the most extensive core backbone network in Greece. Their fiber optical network stretches over 4166 km nationwide and recently they’ve started offering an on-demand interactive video service called “hol video club” that has really taken off. Despite the challenges of the European economic situation, hol is continuing to see not just increases in bandwidth demand but also gains in the number of subscribers. Most recently they’ve seen increasing growth in cloud-based services as well.

Hol is also one of the most recent carriers to put Cisco’s 100G coherent optical solution through its paces. For hol, 100G offers a solution to meet their need for as-needed, cost-effective bandwidth growth without the need to replace any fiber infrastructure. This is a common situation – carriers are finding the 10G links are no longer sufficient; yet running multiple 10Gs in parallel is not optimal. The challenge has been finding a solution which simply enables “plug in play” upgrades to 100G. This was one of the key objectives of the Cisco engineering team who developed the 100G DWDM solution. To make 100G widely deployable and commercially successful, it needed to have similar performance and engineering specifications as previously deployed 10G links.

One of the topics we covered this week at the Cisco Packet Optical Networking Conference was cloud computing. A benefit of cloud computing is that the physical infrastructure – the storage and compute resources – can be located almost anywhere as long as there is reliable network access. Several countries are leveraging their low cost green power to grow their economies with new data center facilities. A publicly announced example of this is Facebook which has built an enormous facility in northern Sweden. Iceland with its cooler temperatures and green geothermal power, plus ideal location between North America and Europe has seen a significant growth in its data center industry. However, being an island nation it faces a challenge to ensure that sufficient cost-effective network capacity is available to connect off-island users with its storage and compute resources.

It’s clearly evident from the evolution of technology that the “need for speed” seems to be deeply embedded in human nature. Reflecting back without going too far back in history, the horse and buggy was the main mode of transportation, unfortunately not fast enough. So we invented the locomotive, automobile, airplane, fax machine, e-mail, and mobile phones with text messaging among the hundreds of other inventions to fulfill our need to do things faster.
Being a networking guy, I might be biased, but I see networks as the new frontier for speed, especially now that we are a media/information driven society. It wasn’t long ago that a 10Mbps shared Ethernet LAN and 56kbps WAN links were considered fast (showing my age here). However, every time faster networking speeds were introduced, newer applications quickly consumed the capacity driving the need for even higher speeds.
Over the years we’ve seen Ethernet speeds increase in increments of 10x starting with 10Mbps to 100Mbps to 1GE and 10GE and now, we’re again at another speed inflection point -100Gigabit Ethernet! This week Cisco added to our 100GE router portfolio (CRS and ASR routers) with the announcement of a 100GE M2-Series module for the Cisco Nexus 7000 Series switches. Along with the 100GE module, we also announced a 40GE M2-Series module for the Nexus 7000 and a 40GE module for the Catalyst 6500.

In case you might have missed it (or don’t read Russian) I wanted to call out two newsworthy items related to Cisco and 100G technology.
Last week at CiscoLive! London we announced the availability of 100GE interfaces on the Nexus 7000 to reduce bandwidth bottlenecks in the data center and help our customers meet the demands of emerging cloud computing applications. With this announcement Cisco becomes the only vendor in the industry offering an end-to-end 100G solution which includes the core (CRS), edge (ASR 9000), data center (Nexus 7000), and coherent DWDM optical transport (ONS 15454 MSTP). Furthermore we’re also one of only a handful of companies in the networking industry that owns (through our acquisition of CoreOptics) the underlying technology needed to make 100G (and beyond) a cost effective reality. With the high forecasted growth rate of the global Internet we believe that our customers will strongly benefit from the unique breadth of our solution to meet both their business and technology requirements.

Earlier this year we wrote about The Gathering, Norway’s largest computer party and how it set a gaming event speed record with a 100GE enabled CRS-3. Like many achievements in the fast moving communication industry, it wasn’t a milestone that stood for long. The new record is now held by their Swedish neighbors who have surpassed that with a 120 Gigabit connection to the Internet at the digital entertainment festival DreamHack. This feat was achieved by TeliaSonera connecting the event site in Jönköping, Sweden with their networking facilities in Stockholm (a distance of approximately 375 km) using the Cisco CRS-3, ASR 9000, and ONS 15454 MSTP. The successful event came from the efforts of some fifty people from Cisco, TeliaSonera, and DreamHack working together to design, build, and test the network.
The event provided not just a showcase for Cisco’s 100 Gigabit coherent optical and IP technologies (see prior post on US Signal), but also a chance to test our equipment under extreme, real world conditions. What non-gamers might not realize is that players actually place great demands on their real-time connectivity (and are quite vocal when something doesn’t work right). Read More »
