Ryo Nakamura, Yuji Sekiya, Hiroshi Esaki
2015 2015 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)  
The method enables us to construct an efficient data center network using commercial off-the-shelf (COTS) switches.  ...  Improving availability and throughput is a significant challenge for data center networks. Recent studies have attempted to use a variety of routing and multipathing techniques.  ...  In contrast to ECMP, SPAIN [12] uses VLAN for multipathing on an arbitrary topology with COTS switches. SPAIN proposes a greedy algorithm to identify each path in a VLAN.  ...
