In this paper we propose Hermes, a highly-robust, distributed fault-tolerant routing algorithm, whose performance degrades gracefully with increasing faulty NoC link counts. Hermes is a deadlock-free hybrid routing algorithm, utilizing load-balanced routing on fault-free paths, while providing pre-reconfigured escape routes in the vicinity of faults. An initial experimental evaluation shows that Hermes improves network throughput by up to 2.2× when compared against the existing state-of-the-art.||URI:||http://ktisis.cut.ac.cy/handle/10488/9515||ISBN:||978-147995347-9||DOI:||10.1109/NOCS.2014.7008782||Rights:||© 2014 IEEE.||Type:||Conference Papers|
