Abstract:

Supporting end-to-end Quality of Services (QoS) in existing network architecture is an ongoing issue. Software Defined Networking (SDN), the new network norm, has emerged in response to the limitations of traditional networks. SDN architecture incorporating Service Oriented Architecture (SOA) brings a network notion of a future service-oriented network. Supporting high dependency on intelligent applications is gradually increasing the demand for high-capacity networks with QoS delivery is vital. The absence of ensuring QoS leads to less reliability and a lower level of trust among the interacting parties, which can significantly impact service-based business. In order to address the pressing issues, the existing studies proposed various solutions; however, most of the solutions are application-based and unable to provide a reliable and personalised QoS guarantee in the SDN network. Moreover, no research has been proposed to provide QoS of future Service Oriented SDN. In order to ensure personalised QoS delivery and enhance to preserve the trust relationships, we have proposed Service Level Agreement (SLA) based framework in SOA-based SDN. The proposed SLA-based framework in SOA-based SDN should address a series of important research questions: (1) How to develop an intelligent method for personalised QoS delivery in SOA-based SDN? (2) How to monitor the QoS of the runtime services in SDN network and pro-actively predict the SLA violation to minimise the risk of SLA violation? (3) How to evaluate the service performance impartially and guarantee a reliable service delivery in SOA-based SDN? (4) How to make an intelligent decision regarding service continuation in considering the deliverable service performance during interactions? This thesis systematically studies how to effectively solve the aforementioned issues with conceptual, theoretical and experimental guarantees. Due to the significance of the aforementioned issue on SOA-based business, it is essential to determine a process that can preserve the SLA contract and trust relationship between the interacting parties. Specifically, this thesis proposes a novel framework SLA-lifecycle-based model to address the issue mentioned above. The primary feature of the framework is that it enables personalised and reliable QoS delivery in SOA-based SDN. In addition, the intelligent framework approach can monitor the network in run-time and predict the possible SLA violation; that information also assists in intelligent decision-making regarding the continuation of the SLA. To validate the framework, we have developed a proof of concept (POC) based implementation including various components such as tools and simulation software and expressed the results with discussion in this thesis.
