RT Journal Article T1 Federation in dynamic environments: Can Blockchain be the solution? A1 Antevski, Kiril A1 Bernardos Cano, Carlos Jesús AB Deploying multi-domain network services is be-coming a need for operators. However, achieving that in a real operational environment is not easy and requires the use of federation. Federation is a multi-domain concept that enables the use and orchestration of network services/resources to/from external administrative domains. In this article, we first characterize the federation concept, and involved procedures, to then dive into the challenges that emerge when federation is performed in dynamic environments. To tackle these challenges, we propose the application of Blockchain technology, identifying some associated high-level benefits. Last, we validate our proposed approach by conducting a small experimental scenario using Tendermint, an application-based Blockchain.
