Abstract: A method of establishing an end-to-end tunnel for a virtual network extending across multiple domains using a first network controller element managing a first domain is provided. The method includes receiving a request from a second network controller element managing the first network controller element for an intra-domain locally-learned tunnel identifier (LLTI), sending an instruction to an egress network element of the first domain to generate the intra-domain LLTI in accordance with the request, receiving the intra-domain LLTI from the egress network element in accordance with the instruction, and sending the intra-domain LLTI to an ingress network element of the first domain. A method of establishing an end-to-end tunnel for a virtual network extending across multiple domains using an inter-domain LLTI is provided.

Abstract: A method for establishing a tunnel between VTEPs includes receiving at an SDN controller a tunnel creation request to establish a VxLAN tunnel from a first VTEP to a second VTEP, determining a VxLAN tunnel of network nodes coupling the first VTEP to the second VTEP, assigning a SvcPI to the VxLAN tunnel, and sending a tunnel initiation command to the first VTEP, the tunnel initiation command causing the first VTEP to convert an Ethernet frame to a path-ID frame by adding an NSH encapsulation header and to forward the path-ID frame to the next network node in the VxLAN tunnel.

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 and system for application-driven proactive multi-stratum resource monitoring in software defined networks (SDN). A Cross-Stratum Optimization (CSO) service orchestrator obtains a service intent, a notification subscription, and a programmable performance rule specified by an application. The CSO service orchestrator collects streaming performance data in a network based on the notification subscription, evaluates performance of the network using the collected data and the programmable performance rule, and allocates one or more of storage, computer, and network resources based on the evaluation to ensure quality of service for the application.
