19.7 OIN ARCHITECTURES AND SYSTEM
DEMONSTRATIONS
Significant research efforts have focused on the use of optical communications in
the context of interconnection networks [25, 26, 28, 29, 30, 44, 51]. In this section,
we review a subset of these architectures that are specifically aimed at advanced
computing systems. The particular points of interest by which an architecture is
evaluated are bandwidth, latency, scalability, and system integration. Additionally,
since contention resolution is one of the key challenges in the design of OIN, the
contention resolution mechanism in each architecture is described. The Data
Vortex architecture and system
