Abstract

It is disclosed a coordinator (), a physical network controller () and methods therein for enabling end-point mobility of a traffic engineering, TE, tunnel in a multi-domain network. Based on a request for virtual network configuration of one or both of the ingress and the egress end-points of the TE tunnel, the coordinator of a multi-domain network determines, Sa second request for virtualizing said one or both of the ingress and the egress end-points of the TE tunnel. The physical network controller may then virtualize end-points of the TE tunnel, providing a virtualized end-point, VEP, TE tunnel, having end-point mobility capacity. Recovery mechanisms of tunnel paths may be efficiently implemented. The present disclosure also provides scalability improvements and operational expenditure, OPEX, savings, as compared to state of art TE tunnels.
