In this context, we introduce a proof-of-concept for a blockchain-enabled QoS-based inter-Autonomous System (AS) routing framework, RoutingChain, that blends a QoS-concerned routing model and blockchain technology. This study's contributions can mainly be stated in five-fold: (i) Competitors-tailored routing coordination framework, (ii) eliminating centralized mediators while coordinating QoS-based inter-AS routing, (iii) an emerging use-case for blockchain technology in networking, (iv) reducing the number of QoS signaling-based message overhead, and (v) mitigating privacy/security concerns in inter-AS routing. Experimental results indicate that the blockchain technology can be applied on E2E QoS-based routing among networks. To the best of our knowledge, this is the first study exploiting the merits of blockchain technology to establish a novel coordination framework for QoS-enabled inter-AS routing in SDN.Institute of Electrical and Electronics Engineers Inc.2020Conference Objecthttps://rdlopen.rawdatalibrary.net/r/bayburt/13543https://doi.org/10.1109/blackseacom48709.2020.9235021978-172817127-22375-8236en2020 IEEE International Black Sea Conference on Communications and Networking, BlackSeaCom 2020info:eu-repo/semantics/closedAccessinfo:eu-repo/semantics/conferenceObjecthttps://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/13543
