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.

We talked before about how over 150 customers from 50 different network operators and enterprises met last month at Cisco’s campus in Richardson, Texas, to attend the Spring 2012 Packet Optical Networking Conference (PONC). Besides collaborating on best practices and future requirements in IP and optical solutions, attendees also had an opportunity to view Cisco’s extensive “brownfield” 100G DWDM demo setup. It consists of over 1000 km of fiber, with 10G services and shows how we can plug-n-play 100G services onto existing live systems. This is a critical requirement for customers who must maintain business continuity while still upgrading the capacity of the network. It’s also using the same technology we showed with EANTC that could go to Read More »

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.

The scale of today’s transport networks and content provider data centers are directly driven by the explosive nature of packet traffic growth. As a result, the demand for 100G and beyond is a key topic in the industry. Cisco’s recent 100G announcement and its industry leading performance for Ultra Long Haul continues to receive significant attention within the service provider community as they consider options for their next generation transport networks.
However, the solution is not only about faster transmission speeds. Service providers must also increase efficiency within their network. Until now, traditional network architectures have inefficiently maintained separate Read More »

Customers from around the world are gathered today at Cisco’s campus in Richardson, Texas to kick off the Spring 2012 Packet Optical Networking Conference (PONC). This brings together network operators, large enterprise customers, optical industry leaders, and Cisco solution teams at a three-day event to collaborate on best practices and future requirements in IP and optical solutions. Some of the key themes that will be featured at this year’s event include:
- 40G/100G Coherent DWDM transport over 10G infrastructure: Much of the infrastructure today was designed to support only 10G wavelengths. It is undesirable to cap and start over with new infrastructure that is purpose built for 40/100G. Cisco’s unique Coherent optical transport technology is a game Read More »
