1. Implementing and evaluating a Self-Stabilizing Software Defined Network Control Plane
   LUNDGREN, ANTON; TANNERUD, IVAN
   Examensarbete på avancerad nivå, 2018 (MSc - Computer Systems and Networks)
   Software Defined Networking (SDN) provides an attractive alternative to traditional, manual, error prone networks. SDN provides the opportunity to add programmability to networks, and decouple the control plane from the data plane. By doing so, a network administrator may control an entire network from a single SDN controller. While the work in this field is...
