Methods and Arrangements for End-Point Mobility of a Traffic Engineering Tunnel of a Multi-Domain Network

A method for enabling end-point mobility of a traffic engineering, TE, tunnel in a multi-domain network, the method being performed by a coordinator of the multi-domain network, where the TE tunnel has an ingress end-point and an egress end-point, the method comprising:

• receiving a first request for a virtual network configuration of one or both of the ingress and the egress end-points of the TE tunnel;
• determining a second request for virtualizing said one or both of the ingress and the egress end-points of the TE tunnel, based on the first request;
• and
• sending the second request to a physical network controller in the multi-domain network.

A coordinator of a multi-domain network, the coordinator being capable to enable end-point mobility of a traffic engineering, TE, tunnel in the multi-domain network, where the TE tunnel has an ingress end-point and an egress end-point, the coordinator of the multi-domain network comprising:

• a processor circuit;
• and
• a memory having instructions executable by the processor circuit, wherein said processor circuit when executing the instructions is configured to:
• receive a first request for a virtual network configuration of one or both of the ingress and the egress end-points of the TE tunnel;
• determine a second request for virtualizing said one or both of the ingress and the egress end-points of the TE tunnel, based on the first request;
• and
• send the second request to a physical network controller in the multi-domain network.

A physical network controller capable to provide end-point mobility of a traffic engineering, TE, tunnel in the multi-domain network, where the TE tunnel has an ingress end-point and an egress end-point, the controller comprising:

• a processor circuit;
• and
• a memory having instructions executable by the processor circuit, wherein said processor circuit when executing the instructions is configured to:
• receive from a coordinator of a multi-domain network, a request for virtualizing said one or both of the ingress and the egress end-points of the TE tunnel;
• and
• virtualize said one or both of the ingress and the egress end-points of the TE tunnel.
