Network Architecture in a converged optical + IP network

摘要

As demands on Provider Networks continue to grow at exponential rates, providers are forced to evaluate how to continue to grow the network while increasing service velocity, enhancing resiliency while decreasing the total cost of ownership (TCO). The bandwidth growth that networks are experiencing is in the form packet based multimedia services such as video, video conferencing, gaming, etc....mixed with Over the Top (OTT) content providers such as Netflix, and the customer's expectations that best effort is not enough you end up with a situation that forces the provider to analyze how to gain more out of the network with less cost.In this paper we will discuss changes in the network that are driving us to a tighter integration between packet and optical layers and how to improve on today's multi — layer inefficiencies to drive down network TCO and provide for a fully integrated and dynamic network that will decrease time to revenue.
