Optimizing the "one big switch" abstraction in software-defined networks

Nanxi Kang, Zhenming Liu, Jennifer Rexford, David Walker
2013 Proceedings of the ninth ACM conference on Emerging networking experiments and technologies - CoNEXT '13  
We believe solutions to this complex problem should be factored in to three distinct parts: (1) high-level SDN applications should define their end-point connectivity policy on top of a "one big switch  ...  Software Defined Networks (SDNs) support diverse network policies by offering direct, network-wide control over how switches handle traffic.  ...  OPTIMIZING A BIG SWITCH A key problem in implementing the one big switch abstraction is mapping global, high-level policies to an equivalent, low-level set of rules for each switch in the network.  ...

Minimizing network complexity through integrated top-down design

Xin Sun, Geoffrey G. Xie
