Loss, Complexity and Cost Analysis of an Optical Switching Fabric Using Fixed Converters
This paper presents a new wavelength converter
sharing scheme for buffer-less switching fabrics, named Shared-
Per-Wavelength-Pair (SPWP). In SPWP fixed wavelength converters
are organized into different pools, each characterized
by a fixed input and output wavelength pair. Packet contention
is solved by assigning incoming packets to wavelength converter
pools with proper wavelength pair. The SPWP scheme
is evaluated and compared to the well-known Shared-Per-Node
scheme, which employs tunable wavelength converters. A simple
cost model which includes also time analysis in relation to the
maturity stage of the optical components has been applied. Packet
loss, complexity, and overall cost have been evaluated highlighting
how the SPWP can be less expensive than or comparable to SPN
in many configurations, while providing the same performanc
