Constructing scalable hierarchical switched openflow network using adaptive replacement of flow table management
S Veeramani, Sachin Sharma, Noor Mahammad Sk · 2013
The need for building large networks is on the rise due to rapid growth of number of internet users and also in data centers where large number of switched networks are formed. Hierarchical structure is the most preferable way of handling complex systems of any kind. Hence in this paper we devise a large hierarchical switched network using OpenFlow and propose the concept of adaptive replacement in flow table to evict uncertain flows at a particular time. Open Flow is a protocol which separates the control plane and data plane which helps in managing flow table and also to place controllers in large hierarchical networks.
