The unprecedented growth of IP based networks over the last decade or so has blurred the traditional distinctions often made between switching and transmission systems in SP networks. Many in today’s IP dominated businesses scarcely acknowledge there is a difference, and maybe what differences there are will eventually disappear, relegated to history’s dustbin.Still, it would be foolhardy to design networks assuming that these two basic aspects of networking did not answer to quite different requirements, since they fulfill entirely different functions in SP networks. If so, does it make sense that one type of packet technology, e.g. IP/MPLS, can be pressed into service for both switching and transmission systems? Read More »
As the global business climate drives the need for increased flexibility in IT services, it will become increasingly important for SPs to dynamically deliver services to their business clients. This Software-as-a-Service (SaaS) business model will provide business customers with the ability to purchase and pay for services on an as-needed basis. To support the SaaS model, SPs will have to create a software layer which sits on top of the CPE and manages the applications and services which are currently being delivered by the SP. This layer will support dynamic, end-user provisioning and will monitor the hardware in the business customer’s environment to ensure resources are available to support the end-user’s processing needs. This will also provide the Service Provider with a source of business intelligence as their sales force will now be able to clearly identify when a customer’s hardware must be upgraded to meet their business needs. By delivering SaaS, the SPs will take a large step in meeting the needs of IT managers trying to stay in front of their company’s constantly changing business needs. Ultimately, I believe it will drive business customers to view SPs as a true partner versus simply a provider of bandwidth.
The 3 min. video here was compiled during a press tour conducted in New York on October 3. On this tour, I met with Reuters, Fortune, The Wall Street Journal and USA Today to discuss the rise of the Experience Provider, the development of the Connected Life and other service provider industry trends and dynamics. This video was done between meetings and features brief observations on dialog with the media on these points.
Service Providers continue to look for the best economics for increasing network capacity to accommodate the continued growth in IP traffic driven by data, voice and primarily video traffic. The advantages of integration have already been witnessed at the transport layers through the integration of SONET/SDH and DWDM. This integration was realized in the form of native DWDM interfaces on SONET/SDH Add Drop Multiplexers (ADMs), cross connects and common management systems. Why IPoDWDM?The reason for integrating IP and DWDM are simply to deliver a significant reduction in capital expenditures and improve the operational efficiency of the network. The premise of IPoDWDM is to reduce the electrical transport layer as much as possible as this provides the highest bit-rate robustness, future protocol robustness and functional robustness. For example, moving an underlying SONET/SDH infrastructure from 10G to 40G requires significant redesign but using some novel modulation formats, accommodating 40G over existing 10G transmission infrastructure is possible. Additionally, modifying an electrical cross-connect from 10G SONET/SDH to Ethernet is not a simple task. Lastly, integration of the IP and DWDM layers can improve the overall reliability of the network by creating visibility of the optical layer into the IP layer enabling faster protection at Layer 3 instead of leaving un-used bandwidth in the network for protection as with SONET/SDH.

Let me start by saying service providers are in a great marketplace. And I’m talking about service providers worldwide. This includes the cable companies and wireline providers, and in many cases the programmers and broadcasters. As we look at the overall market, there are a number of product and service advancements fueling service provider growth that stand out. The bundle is one of the most important drivers in the marketplace right now. The bundle is working. The common strategy is to lock in the customer who is buying more, while paying less for the bundle. Then you develop customer loyalty, reduce churn and use the devices that are in the home, and up-sell new applications. Read More »
