| dc.description.abstract | Software-defined networking (SDN) offers several benefits by separating the
control plane from the data plane of network. However, in this framework, the whole
network will rely on the controller which is the heard of SDN architecture. The
problems such as single of failure or workload issue will occur if there is only one
controller in the network. This paper presents the solution to make multi controllers
working together as a complete system with fault tolerance, high available and
consistency. This approach takes the advantages of distributed network to solve the
current problems. In the study, I apply the distributed Ring election to make
controllers have their own roles and functions. The paper also integrates the benefits
of gnutella protocol for exchanging information between controllers and replicating
the network database. In addition, by the advanced function of distributed file
sharing, Gnutella provides the effective way for network data replication. In the
study, I have built the Lab for testing, developing the approach and evaluating the
result to have experience. | en_US |
