Abstract
Scale-out architectures supporting flexible, incremental scalability are common for
computing and storage. However, the network remains the last bastion of the traditional
scale-up approach, making it the data center's weak link. Through the UCSD Triton network
architecture, the authors explore issues in managing the network as a single plug-and-play
virtualizable fabric scalable to hundreds of thousands of ports and petabits per second of
aggregate bandwidth.
