Description
This paper presents an inter-domain transport net-work 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 end-To-end SLA of the transport network slice is violated, the slice is reconfigured avoiding the domain that originated the violation. © 2022 IEEE.
Notes
In this demonstration, we showcase the feasibility of the proposed inter-domain solution, where a number of TFS controller instances collaborate to provide End-to-End Transport Network Slices. To this end, we will detail the design of the IDC, that features service preparation and activation, service modification, and synchronization of service monitoring data between domains through the Blockchain.
