Triple Play Support for the Next Generation Internet

Inhalt:
The Internet has the potential to become the ubiquitous and universal means of accessing any type of information, whether pulled by the user or pushed by a provider. However, in order to be the infrastructure of choice for this role, the Internet must represent a business opportunity to information providers or, at least, be economically selfsustainable. In other words, Internet technology must support services in such a way that both people are willing to pay for them and the cost of delivering them is low. The former implies that services, besides being appealing, must be reliable and of reasonably high and persistent quality. The latter requires low complexity technological solutions and convergence to a single network infrastructure that supports, in an integrated manner, traditional Internet applications (e.g., web, e-mail, and file sharing), telephony, and video, a.k.a. triple play. Since today’s solutions resort to overprovisioning to satisfy the quality requirements, they fail to minimize costs due to low resource utilization efficiency. This paper presents a low complexity solution for proving triple play services as it enables integrating different applications so that each received the service it requires, possibly in a guaranteed fashion, while ensuring high resource utilization efficiency.
