ETSI Technical Committee TC SES has released a new two-part specification, ETSI TS 102 856, to enable Multi-Protocol Label Switching (MPLS) interworking between satellite and terrestrial networks. The document defines necessary architectural adaptations and protocol stacks to ensure reliable Quality of Service (QoS) and traffic engineering across broadband satellite multimedia systems. Part 1 outlines various network architecture variants and resiliency provisions, while Part 2 details the specific signaling procedures required for fully integrated MPLS deployments. This standardization effort, funded by the European Commission and EFTA, aims to provide satellite operators with a framework for extending terrestrial MPLS capabilities or establishing backup links.
