Abstract
A large-scale switching system deployed as a global network or a large-scale data center includes a large number of access nodes (edge nodes) interconnected through optical or electronic rotators. The rotators are logically arranged in a matrix and each access node has a channel to each rotator in a respective row and a channel from each rotator of a respective column of the matrix. A dual timing circuit coupled to a diagonal rotator pair exchanges timing data with edge nodes connecting to the diagonal rotator pair to facilitate temporal alignment of data received at input ports of each rotator. Each access node has a path to each other access node traversing only one of the rotators. The rotators may be arranged into constellations of collocated rotators to facilitate connectivity of access nodes to rotators using wavelength-division-multiplexed links.
