Light Peak is a new optical interconnect technology
developed by Intel and targeted at connecting computing and
consumer electronic devices. It provides bandwidth of 10Gbps
and higher using optical fiber technology, but at extremely low
cost. This paper investigates whether Light Peak technology
can be leveraged to form the basis of a low-cost, high
performance, scalable network. This paper presents our
feasibility analysis, supported by a prototype network we
constructed. The prototype consisted of a number of Light
Peak PCI-Express cards, each with one host interface, an
integrated switch, and transceiver pair with four optical ports.
With very small forwarding delays, Light Peak supports direct
networks with topologies that have interesting traffic
characteristics suitable for small-scale clusters (containers with
1,000-10,000 servers).
