Datacenter Networks and Relevant Standards [chapter]

Daniel S. Marcon, Rodrigo R. Oliveira, Luciano P. Gaspary, Marinho P. Barcellos
2015 Cloud Services, Networking, and Management  
Overview Datacenters are the core of cloud computing, and their network is an essential component to allow distributed applications to run efficiently and predictably [17] .  ...  A Clos network [25] consists of multiple layers of switches; each switch in a layer is connected to all switches in the previous and next layers, which provides path diversity and graceful bandwidth degradation  ...  In fact, most physical data center designs are unique: hence expansions and upgrades must be custom-designed and network performance (including bisection bandwidth, endto-end latency and reliability) must  ...

Expander Datacenters: From Theory to Practice [article]

Vipul Harsh, Sangeetha Abdu Jyothi, Inderdeep Singh, P. Brighten Godfrey
2018 arXiv   pre-print
Recent work has shown that expander-based data center topologies are robust and can yield superior performance over Clos topologies.  ...  In this paper, we examine if expanders can be effective for the technology and environments practical in today's data centers, including the use of traditional protocols, at both small and large scale  ...  LEGUP [15] proposed a design to build heterogeneous Clos networks for flexible expansion.  ...

We also show that Condor supports the daunting task of designing multi-phase network expansions that can be carried out on live networks.  ...  The design space for large, multipath datacenter networks is large and complex, and no one design fits all purposes.  ...  Our approach is especially valuable for designers of largescale data-center networks, because of the complexity that arises at larger scales, but it should also be useful to many organizations with medium-scale  ...
