As both corporate and residential customers adopt more and more Internet-based applications, they naturally are asking their service providers to deliver more and more bandwidth-intensive services. If service providers are to protect their margins, market share and long-term profitability, they obviously must ensure they have sufficient network capacity to keep pace with the growing demand. At the same time, however, competitive pressures are forcing them to seek out more cost-effective ways to continue delivering that additional capacity.
When it comes to increasing network capacity, service providers basically have two choices: either they can build bigger networks, or they can look for ways to squeeze more capacity from their existing fiber infrastructures. The first option involves parallel overbuilds of the transport network. For example, as service providers exhaust the capacity of their existing DWDM platforms, the non-scalable architecture of many such systems forces them to invest in a second platform. To obtain twice the capacity of the current platform, service providers have to invest in twice the fiber and associated equipment, a deployment scenario that affects multiple network sites and significantly slows down operations. To make matters worse, this scenario requires service providers not only to invest in additional fiber and equipment but also to spend money and time in moving traffic onto the parallel systems.
Because capacity demand--both current and forecasted--varies...
