Performance Issues in Optical Burst/Packet Switching [PDF]

, 2009
This chapter summarises the activities on optical packet switching (OPS) and optical burst switching (OBS) carried out by the COST 291 partners in the last 4 years. It consists of an introduction, five sections with contributions on five different specific topics, and a final section dedicated to the conclusions.

Time-Sliced Flexible Resource Allocation for Optical Low Earth Orbit Satellite Networks

IEEE Access, 2019
In future optical satellite networks with various service requirements, the bandwidth of a single traffic request occupies part of an inter-satellite link (ISL) channel capacity, thus leading to a greater demand for flexible resource allocation.

All-Optical Packet Switching and Label Rewriting for Data Packets Beyond 160 Gb/s

IEEE Photonics Journal, 2010
In this paper, two different paradigms to realize a scalable all-optical packet switch with label swapping will be reviewed. The two paradigms are based on wavelength routing switch and space routing switch.
