The demand for increased bandwidth is constant, and to avoid investing huge amounts in new systems, most operators, if not all of them, are looking to re-use their existing fiber infrastructure. This, however, poses a problem because the standard train of “1” and “0”, called on-off keying (OOK), simply can’t be pushed any further on most of the installed bases.

Broadband, backbone and mobile wireless service providers see the cloud as an opportunity for growth. New applications running in the cloud drive new traffic to their network.  The cloud also offers new revenues from new services that can be marketed to consumers.  The complex relationship between Cloud providers and carriers is rapidly evolving, but one fact is clear: to achieve success in the cloud market, carriers and providers must actively ensure that they offer a high quality of service to cloud consumers.  Whether a cloud carrier, cloud provider or both, this white paper will explain the importance of visibility into the cloud.  It also explains the tools and metrics necessary to provide speedy delivery and high-quality of service and experience demanded in today’s environment.

With 100G set for mass deployment in order to address the growing demand for bandwidth, both service providers and network operators are facing a number of challenges. Some of these challenges are related to the multiservice offering of 100G networks, the nature of each and every one of its supported services, and its implications on service-level agreements (SLAs). And, as the service offering scales to the 100G rate and becomes more and more complex, network engineers are being called on to perform even more troubleshooting and service calls.
