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. In PI-OBS, all the headers received during a given time window are jointly processed to optimize the delay and output wavelength allocation, applying void filling techniques, and allowing traffic differentiation. Results show a similar...
This paper surveys a set of relevant techniques proposed for traffic shaping in backbone OBS/OPS networks. The work is intended to fuel the near future research in the topic the authors will conduct within BONE project.
In this paper, the wire-speed packet processing issue is studied for optical packet/burst switching (OPS/OBS) switching nodes as well as for wavelength-routing (WR) switching nodes. Some assumptions are made to obtain simple estimates of the requirements in terms of forwarding events per second. This is compared with the packet processing performance of electronic devices which implement this type...
