We study the restorability performance of shared trees and examine the limitations of such schemes in specific topologies, such as cases where long node chains exist.
We also apply our algorithms to the problem of designing the protection tree in a pre-designed fixed-capacity network, and study the performance of shared protection trees in this scenario under different network loads and link utilization levels.
We leverage the checkpoint technology and design a novel approach based on the hybrid waiting list named Chord (Checkpoint with hybrid scheduling method) which effectively improves the performance of shared clusters.
A channel selection scheme for CR nodes for a multichannel multiuser environment is also proposed-based on Poisson traffic model in [25], and recently in [26, 27] we have studied the performance of shared spectrums sensing for UWB-based CR assuming the Poisson model for the PU.
This shows that the consideration of traffic dynamics is a crucial point of the performance evaluation of shared bandwidth systems, and it encourages further investigations of the relation between physical layer parameters and flow-level performance.
The lower performance of shares in companies audited by Andersen from November through April may reflect, in part, a greater loss of confidence in those companies by investors.
Most normal people are happy to thank their lucky stars for the buoyant performance of shares, on average, both recently and over the long run.
