2017 arXiv   pre-print
Hybrid circuit and packet switching for data center networking (DCN) has received considerable research attention recently.  ...  Our first algorithm, called 2-hop Eclipse, strikes a much better tradeoff between the resulting performance (of the hybrid switch) and the computational complexity (of the algorithm) than the state of  ...  In a hybrid data center, shown in Figure 1 , n racks of computers on the left hand side (LHS) are connected by both a circuit switch and a packet switch to n racks on the right hand side (RHS).  ...
