A scalable router-switch that grows from a capacity of a few gigabits per second to hundreds of terabits per second is disclosed. In one embodiment, the router- switch comprises a plurality of switch units arranged in a plurality of combinations. Within ea ch combination, each switch unit cyclically connects to each other switch unit to form a contenti on- free temporal mesh. Each switch unit belongs to a number of combinations and any two combinations have at most one switch unit in common. The router-switch further includes a distributed-control system which comprises an outer controller associated with each of the switch units and an inner controller associated with each combination. The structural simplicity significantly simplifies the operation and control of the router-switch.
