Objectives
The aim of this study was to evaluate the differences in surgical capacity for head and neck cancer in the UK between the first wave (March‐June 2020) and the current wave (Jan‐Feb 2021) of the COVID‐19 pandemic.
Design
REDcap online‐based survey of hospital capacity.
Setting
UK secondary and tertiary hospitals providing head and neck cancer surgery.

Optical switching fabrics are gaining interest as in multi Terabit switching devices; the advantages over their electronic equivalents are mainly their information density and power consumption. Arrayed Waveguide Gratings (AWGs) are promising optical devices proposed by the academic and industrial community to build optical switching fabrics. Because of their wavelength routing property, AWGs allow...
The rapid growth of the Internet traffic demand is bringing the current electronic switches closer to their intrinsic technological limits, which may be overcome by optical technologies. Although optical packet switching has been widely studied in academia; the limited processing and buffering capabilities available in the optical domain makes the implementation of an all optical packet switch difficult...
Passive optical networks (PONs) represent a step forward in "first mile" networks; indeed, by using optical technologies, PONs can transfer a large amount of data, and by being completely passive, they reduce management costs and failure probabilities. Access network is logically a point-to-multipoint network and the tree topology emerged as the winning solution; however, it naturally lacks...
Disaster recovery and business continuity issues are becoming fundamental in networks since the importance and social value of digital data is continuously increasing. On the one hand, there is an obvious need of backing up data for resilience against major failures; in many situations the process of storing backup data is also enforced by the law. On the other hand, providing services that allow...
