PI-OBS: a Parallel Iterative Optical Burst Scheduler for OBS networks [PDF]
, 2009 This paper presents the PI-OBS algorithm, a parallel-iterative scheduler for OBS nodes. Conventional schemes are greedy in the sense that they process headers one by one.

Virtual topology design in OBS networks [PDF]
, 2010 The problem of burst losses in OBS networks has an impact on the service quality perceived by end users. In order to guarantee certain level of Service Quality (QoS) in terms of burst losses, wavelength resources have to be dimensioned properly.

Queueing Models Performance Analysis in Optical Switching Network Nodes [PDF]
, 2023 In optical switching networks, queueing models are often used for modeling, analyzing, and evaluating the performance of switching nodes. These models determine the number of optical packets in the switch and how quickly the switch can serve the traffic.
