DLT-based End-to-end Inter-domain Transport Network Slice with SLA Management Using Cloud-based SDN Controllers: Demo Session

Abstract

This paper presents an inter-domain transport network slice management with Service Level Agreements (SLA) using the ETSI TeraFlowSDN (TFS) controller. Different instances of the TFS controller are deployed for each involved domain. The communication between the TFS instances is supported by a Distributed Ledger Technology (DLT)-based database. The different TFS instances upload the abstracted view of their topologies and retrieve that from remote peers. When the endto-end SLA of the transport network slice is violated, the slice is reconfigured avoiding the domain that originated the violation.
