The challenges awaiting future data networks are not only the sine qua non issue of high bandwidth, but also failure resiliency and power consumption. This can be addressed by a cross-layer physical impairments awareness permeating the network, whose elements can then be reconfigured on the fly so as to optimize transmission capacity, energy efficiency, and recovery time. We demonstrate an impairment-aware...
Cross-layer communications allows future optical access/aggregation networks to meet stringent bandwidth and performance demands by facilitating the dynamic management and optimization of network routing based on performance monitoring measurements and other higher-layer attributes. Our work endeavours to design and demonstrate a test-bed of intelligent cross-layer optimized network interfaces that...
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.
A major challenge in meeting the enhanced performance requirements of next-generation optical networks is overcoming the rigid limitations due to network layering. Our work addresses this issue by creating a bidirectional cross-layer communications infrastructure that can leverage knowledge of the optical-layer performance to improve network performance. The goal is to create an intelligent, dynamic,...
