Blockchain-Based Connectivity Provisioning in Multiple Transport SDN Domains

Abstract

Hierarchical Software Define Networking (SDN) architectures is used to manage the co-existence of multiple domains by having an element on top. A collaborative relation-ship between domains, might solve this issue. Blockchain may become the key element for this change to happen. This paper presents a Blockchain-based architecture to provide SDN actions to configure connectivity services in transport domains. The results presented show that the use of Blockchain is a promising candidate for inter-domain SDN control.
