抄録(和) Recent literature on traffic control in datacenter intra- and interconnect has moved from optical burst switching and FCoE to the cut-through mode enforced e2e on commodity ethernet lines. E2e cut-through sessions -- aka, effectively, circuits -- are implemented as optimized schedules in which bulk transfer sessions are mixed with a large number of small flows. This paper presents a new optimizational viewpoint, formulated as the Switchboard Traffic Engineering Problem (STEP). First, the mixed schedule of input flows is mapped to a finite number of (physical) output lines some of which are implemented as (physical) e2e cut-through paths. The second part of the problem is to physically shuffle input ports (hence the switchboard) on switches with output lines in such a way that overall contention is minimized. This paper deals with the formulation of the optimization problem and leaves the otherwise obvious (robotics) implementation of the shuffling part of the technology to future publications.
