Abstract: Segment Routing (SR) has emerged as a promising source-routing methodology to overcome the challenges in the current routing schemes. It has received noticeable attention both, in industry and academia, due to its flexibility, scalability, and applicability, especially in Software Defined Networks (SDN). The emerging cloud services require strict Service Level Agreements (SLAs) such as packet loss, delay, and jitter. Studies have shown that traditional network architectures lack the essential flexibility and scalability to offer these services. This has led to introduction of a more flexible and agile routing paradigm of SR that enables a source node to steer an incoming packet along a performance engineered path represented as an ordered list of instructions called segment list and encoded as a MPLS label stack or an IPv6 address list in the packet header. This thesis provides a comprehensive review of the novel SR technology by describing its architecture, operations, and key applications to date. The study reveals that the SR paradigm can be effectively applied to a wide range of network applications, such as Traffic Engineering (TE), network resiliency, network monitoring, and Service Function Chaining (SFC), to achieve efficient network solutions. Moreover, this thesis introduces an efficient SR based network monitoring technique that can be applied to partitioned networks to minimize the routers overhead. Furthermore, the study identifies an interesting set of future research directions and open issues that can help realize the full potential of the emergent SR paradigm.
