摘      要：Modular datacenters (MDCs) use shipping containers,encapsulating thousands of servers,as large pluggable building blocks for mega *** MDC’s service-free model poses stricter demand on fault-tolerance of the modular datacenter network (MDCN).Based on the scale-out principle,in this paper we propose SCautz,a novel hybrid intra-container network for *** comprises a base Kautz topology,created by interconnecting servers,and a small number of COTS (commercial off-the-shelf) ***,each switch connects a specific number of servers forming clusters,which,as logical nodes,form multiple higher-level logical Kautz ***’s hybrid structure has several ***,it supports multiple running modes for the MDC,while its full structure increases network capacity ***,it retains the throughput for processing one-to-x traffic in the presence of ***,it achieves much more graceful network performance degradation than computation and storage capacity *** from theoretical analysis and simulations show that SCautz is more viable for intra-container networks.
