Demonstration of QoS-Aware Video Streaming Over a Metro-Scale Optical Network Using a Cross-Layer Architectural Design
Source: North Carolina State University
QoS-aware video streaming is demonstrated on an optical network using a service-oriented architecture and a NetFPGA-based optical control plane. Dynamic optical power fluctuations are either compensated or the lightpath is rerouted to ensure the QoS. The layered architecture of the current Internet is becoming increasingly strained in supporting the ever-increasing number of users and applications. Today's optical networks assume a highly reliable physical layer with low Bit-Error Rates (BERs) through over-provisioning of the network capacity. As the bandwidths carried by these optical channels increase, the traditional manner of over-provisioned optical transport capacity may no longer be economically feasible.
