“…The evaluation metrics for the SDN protocols were highlighted by the survey of Mendiola et al [4] who indicated that the number of messages and the size of the messages were criteria for the measurement scalability of the SDN solutions. Based on this claim, the signaling overhead was measured of the proposed architecture for the size of East/Westbound messages.…”

Abstract:The Border Gateway Protocol (BGP) is the current state-of-the-art inter-domain routing between Autonomous Systems (ASes). Although BGP has different mechanisms to manage outbound traffic in an AS domain, it lacks an efficient tool for inbound traffic control from transit ASes such as Internet Service Providers (ISPs). For inter-domain routing, the BGP's destination-based forwarding paradigm limits the granularity of distributing the network traffic among the multiple paths of the current Internet topology. Thus, this work offered a new architecture to manage incoming traffic in the inter-domain using OpenFlow networks. The architecture explored direct inter-domain communication to exchange control information and the functionalities of the OpenFlow protocol. Based on the achieved results of the size of exchanging messages, the proposed architecture is not only scalable, but also capable of performing load balancing for inbound traffic using different strategies.

“…This is done by applying a hash function over the set of packets' header fields. Since OpenFlow switches can use a wide range of classifiers to forward packets [11], fine-granularity of traffic splitting is expected [5]. Unequal traffic splitting ratios could be implemented with Group tables in the processing pipeline of OpenFlow switches [11].…”

“…However, PCE based architecture also suffers from slow path establishment issues, since it relies on distributed Resource Reservation Protocol (RSVP-TE) to set up, maintain and tear down traffic tunnels. Moreover, from the TE perspective, there is an issue with per-flow traffic splitting granularity in multipath routing, which is determined by the forwarding element capabilities and might deviate significantly from that assumed by TE solution [5]. This motivated emergence of Software Defined Networking (SDN) architecture with out-of-band programming capabilities and higher granularity of traffic control [5].…”

-In this paper, we propose a new approach to virtual-link provisioning in ISP (Internet Service Provider) networks. The approach relies on Software Defined Networking (SDN) architecture based on OpenFlow that allows highly granular traffic splitting across multiple paths. The traffic control logic of SDN controller is divided into offline and online component. The online component handles dynamic arrivals of virtual-link requests in accordance with Service Level Agreements (SLAs) requirements. The offline component is responsible for periodic optimization of traffic distribution in the network. In this way, we tend to increase acceptance ratio for virtual-link requests and minimize degradation of best-effort traffic in a scalable manner. Our simulation results show that the proposed method for virtuallink provisioning outperforms solutions that rely on Constrained Shortest Path First (CSPF) and Equal Cost Multi-Path (ECMP) routing.

Network Application Design Challenges and Solutions in SDN

Software-Defined Networking (SDN) is a promising network architecture that proposes the decoupling of data and control planes. It uses a logically centralized controller powered by a global view to orchestrate the network, enabling innovation by shifting the task of network administration to network programming. Many SDN applications are designed to work autonomously without intervention, and thus they need to monitor the state of the network in order to take appropriate actions, and improve their future decisions. Furthermore, in the case of physically distributed SDN controllers, applications also need to exchange their views in order to build a global network view. This great shift in how networks are perceived gave birth to many new network applications design challenges.In this dissertation, we identify some of these challenges and study how they could affect the performance and security of SDN applications. In particular, we focus on the problem of inconsistent network view at the controllers and its impact on the network applications. We identify two key factors that can contribute to the inconsistent network view at the controllers: (1) network state collection; and (2) controllers' state distribution. We investigate different manifestations of the impact of network state collection and distribution on network applications performance and security. Moreover, we show that different network applications have different consistency requirements, and hence we introduce adaptive distributed SDN controllers as a solution to the controllers' state distribution. Adaptive controllers can tune their i First and foremost, I wish to thank my supervisor Dr. Ashraf Matrawy for his guidance, advice, and more importantly for his patience throughout this dissertation. I would like to thank my PhD committee members Dr. Chadi Assi, Dr. Chris Smelser, Dr. Dimitrios Makrakis, and Dr. Jason Jaskolla for reviewing my dissertation and providing me with their insightful feedback and comments. I would also like to thank my research group colleagues for their fabulous support, and for the fruitful dicussions and the meetings that we had. Last but not least, I would like to express my deepest gratitude and appreciation to my family and friends. Special thanks should be given to my father Abdelsalam, my mother Shoukran, my brothers Khaled and Mahmoud, and my sister Ghada for giving me the encouragement and motivation that I really needed. iv Contents Abstract i Acknowledgments iv List of Figures x List of Tables xiii List of Abbreviations xv CHAPTER 3.
