The ability to deploy new equipment and services in a timely and cost-effective manner – a quality known as network agility– is crucial to maintaining profitability. Bottlenecks that hinder deployment, reduce performance, or result in downtime add cost to every operation. For example, managing thousands of IP addresses by hand creates bottlenecks when provisioning and troubleshooting as well as increases the possibility of service outages caused by human error.
The growing complexity of networks further increases the difficulty of managing today’s networks. Operators must accommodate new types of servers and clients, potentially from multiple vendors. TCP/IP continues to connect more devices, resulting in a higher cost to manage each new device as the number of devices added to the network increases. Furthermore, new technologies like IPv6, virtualization, cloud services, and mobile connectivity which increase management complexity drive the need for comprehensive, integrated, and feature-rich IP address management (IPAM) capabilities.

Today, many organizations are focusing on how to integrate IPv6 services into their Internet edge. The World IPv6 Launch has come and gone with over 3000 sites now IPv6-enabled. In addition, the US government has directed that all agencies must enable their Internet facing services for IPv6 by October 1st, 2012. These drivers are pushing organizations to take a harder look at how to approach IPv6 integration. My next couple of posts will examine how to interface with your Internet Service Provider (ISP).
The Internet edge is the point in your network where your organization will interface with the IPv6 Internet, and it is how customers will access your services. It is important that your ISP have the same Service Level Agreement (SLA) as your IPv4 point of attachment. After all, you are going to be running your business over both IPv4 and IPv6 for quite some time. To ensure that your ISP’s IPv6 services meet your business and technical requirements, I’ve compiled a list of questions to ask. The questions are grouped along the lines of how IPv6 is physically delivered, how the control plane is handled, and the services that are offered. The following are several example questions:

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.

The insatiable demand for smartphones, tablets, and other connected devices is generating staggering amounts of mobile data. As my previous blogs discussed, the use of Wi-Fi for Internet access is exploding as more mobile devices are Wi-Fi-enabled, the number of public hotspots expands, and user acceptance grows. Service providers (SPs) now realize Wi-Fi must be an important part of their strategy to manage growing data loads on their networks and meet increased customer expectations. While operators are learning to accept the role of Wi-Fi, they still struggle with ways to turn a “cost of doing business” into profitable business models. The Cisco Internet Business Solutions Group (IBSG) has consulted with leading SPs from around the world about new, innovative Wi-Fi business models that can provide a reasonable return on investment (ROI), as outlined in our paper, “Profiting From the Rise of Wi-Fi.”
To learn more about what consumers are doing with their mobile devices, and to test their response to the new Wi-Fi business models, Cisco IBSG recently conducted a survey of U.S. mobile users. Following are our top three findings related to monetization of Wi-Fi: Read More »

These days it seems like practically every networking conversation I have involves mobility. It makes sense because with this “always on” lifestyle, people have a wide variety of motivations and desires to connect to one another near and far in both fixed, nomadic, and truly mobile situations, whenever they want, wherever they want. And in many developing areas of the world which may not necessarily have the need for “constant connectivity,” they are turning to mobility for “connectivity” in general since it is possible to get much more broadband coverage, so quickly. In fact, our Cisco VNI team forecasts that there will soon be more people connected to the Internet, largely through mobile means, than there will be connected to electricity. Pretty amazing.
But with all of this talk of mobility whether it be discussions of NGH or advances in EPC innovations and architectures or competing market claims of this vs. that, it can at times be confusing (editor note: this author most certainly not exempt from that….)
So to break through that noise of all the mobility talk, we looked for truth in numbers – numbers on the market, where it’s been and where it’s going, and what’s Cisco’s role in enabling it all. Here is what we found: Read More »
