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).
