DLG-Hypertree: A Low-Diameter, Server-centric Datacenter Network Architecture

The architecture of data center networks (DCN) is critical to the performance of cloud computing. Hyper tree is a novel interconnection structure which assures low diameter as well as high fault tolerance. We utilize the "distributed line graph" (DLG) technique on hyper tree to design an efficient DCN architecture, called DLG-Hyper tree (DH). We implement a prototype of DH using the Owlet language. The effectiveness of DH is demonstrated through simulation and evaluation on the prototype of DH.
