Title: | RESILIENCE IN SOFTWARE DEFINED NETWORKS | Authors: | PURNIMA MURALI MOHAN | ORCID iD: | orcid.org/0000-0003-3176-8453 | Keywords: | SDN, Resilience, Controller mapping, Local Rerouting, Secure routing, OpenFlow | Issue Date: | 18-Jan-2018 | Citation: | PURNIMA MURALI MOHAN (2018-01-18). RESILIENCE IN SOFTWARE DEFINED NETWORKS. ScholarBank@NUS Repository. | Abstract: | Software Defined Networking (SDN) handles complex functions at a centralized control-plane, and the data-plane performs forwarding based on control-plane decisions. The key challenges in providing resilience towards attacks/failures in SDN are posed by the inherent features of SDN itself. This thesis is devoted to investigating the attacks and failures that could degrade SDN and proactively enable resilience towards such attacks/failures with efficient resource management. First, we address Byzantine threats on the SDN control plane, while considering the control traffic load and capacity constraints. We then enhance the resilience of the in-band control path on the southbound interface in SDN with malicious switch detection. Third, we address the problem of proactive fault tolerance in SDN data-plane, considering TCAM and bandwidth costs. Finally, we address dynamic attack-resilient routing problem considering the node reliability and load for SDN-enabled networks. We carry out comprehensive performance study to demonstrate the effectiveness of our solutions. | URI: | http://scholarbank.nus.edu.sg/handle/10635/142761 |
