    Abstract: A method performed by a Next Generation Node B (gNB) in a communications system implementing User Datagram Protocol (UDP) comprises indicating that a data packet comprises a multi-transport network context-identifier (MTNC-ID) corresponding to a forwarding path and being associated with a set of resource provisioning requirements for one or more transport networks on the forwarding path to provision transport resources for traffic forwarding on the forwarding path, inserting the MTNC-ID into a Generic UDP Encapsulation (GUE) header of the data packet, and transmitting the data packet to a network element (NE) in the communications system based on the forwarding path corresponding to the MTNC-ID.

    Abstract: A method for transporting a Multi-Transport Network Context Identifier (MTNC-ID) over a Segment Routing Version 6 (SRV6) enabled data plane for fifth generation (5G) transport. The method includes setting an indicator in a flags field of a SRV6 header of a data packet that an MTNC-ID type-length-value (TLV) is included in a TLV field of the SRV6 header. The MTNC-ID TLV for the MTNC-ID is inserted in the TLV field of the SRV6 header of the data packet. The data packet with the SRV6 header containing the MTNC-ID is transmitted over the SRV6 enabled data plane to a next node along a forwarding path corresponding to the MTNC-ID.

    Abstract: A method for transporting a Multi-Transport Network Context Identifier (MTNC-ID) over a Segment Routing Version 6 (SRV6) header for fifth generation (5G) transport. The method receives a data packet that includes an MTNC-ID in a data plane header of the data packet. The MTNC-ID is extracted from the data plane header of the data packet, and is encapsulated in an argument field in a last segment of a segment list (SL[0]) of the SRV6 header of the data packet. An instruction for forwarding the MTNC-ID is encapsulated within a function field in the SL[0] of the SRH of the data packet. The data packet is transmitted over a SRV6 enabled data plane domain along a forwarding path corresponding to the MTNC-ID.

    Abstract: A network analytics engine predicts impairment of one or more communications links included in a current data path being used to transmit data through a network, and transmits information indicating the predicted impairment to a network controller in a warning message. In response to receiving the warning message, the network controller identifies potential alternative data paths that exclude any communication links predicted to experience an impairment. Before setting up an alternative data path, however, the network controller waits for a fault notification confirming the predicted impairment. If the fault notification is received before expiration of a waiting period, the network controller sets up one of the potential alternative data paths in place of the current data path.
