Experimental Multi-Failure Protection Solution Using Directed Spanning Tree with Ryu Controller in Software-Defined Networks
Tran The Hieu, Nattapong Kitsuwan (UEC) CS2024-45
Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents an innovative rerouting approach for multiple link failures, using directed spanning trees and MPLS technology for enhanced resilience. Our solution, implemented on PICA-8 switches with the Ryu controller, constructs optimized directed spanning trees through ILP and heuristic methods, reducing the number of required flow configurations
compared to OSPF. Experimental results show a 38.96% decrease in initial flow configuration and up to 60.38% reduction during multiple link failures. This approach ensures swift recovery without additional hardware, efficiently responding to network failures, and reduces required memory and traffic in the control plane.
