摘要： 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.

摘要： A method implemented by a central controller is provided. The method includes receiving traffic monitoring information from a client, and sending a traffic monitor request to a network controller, the traffic monitor request requesting the network controller to monitor one or more traffic parameters based on the traffic monitoring information. The method further includes receiving a traffic report from the network controller, and responsive to determining that a monitored traffic parameter in the traffic report does not satisfy a condition specified by the traffic monitoring information, initiating a scaling operation based on data contained in the traffic report.

摘要： 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.

摘要： A method implemented by a customer network controller (CNC) in a network comprises storing, by a memory of the CNC, a mapping between a virtual local area network (VLAN) identifier (ID) of a VLAN, an application ID of an application executed in the VLAN, and a service policy associated with the application, the service policy defining a network requirement for the application, the VLAN being associated with a customer edge (CE), transmitting, by a transmitter of the CNC, a tunnel creation request comprising the VLAN ID, the application ID, and the service policy, and storing, by the memory, a tunnel ID of a tunnel established in response to the tunnel creation request, the tunnel defining a path between an ingress provider edge (PE) node and an egress PE node that satisfies the service policy.

摘要： A customer network controller (CNC) including a processor and a memory. The processor is configured to use a virtual private network (VPN)-specific service model for a VPN service and map the VPN-specific service model to one or more traffic engineering (TE)-specific parameters. The memory is coupled to the processor and configured to store a mapping between a VPN identification (ID) of the VPN service corresponding to the VPN-specific service model and a tunnel ID of either an existing TE tunnel or newly-established TE tunnel for the VPN service. The existing TE tunnel or the newly established TE tunnel satisfies the one or more TE-specific parameters.

摘要： A method for establishing end-to-end tunnels extending across multiple domains using a network element. The method includes receiving a request from a customer controller to implement a virtual network (VN) created by the customer controller, wherein the VN identifies the end-to-end tunnels extending across the multiple domains, mapping the VN to available resources based on network constraints in response to the request, and transmitting, after the VN has been mapped, a message to a network controller managing one of the domains that includes a network path used to form a portion of one of the end-to-end tunnels, wherein the message includes an association object having a Type-Length-Value (TLV) field containing a virtual network identifier binding the network path to the VN.

摘要： A computer-implemented method of requesting a path on a flexi-grid network comprises: sending, by a path computation client (PCC), a request for a path to a path computation element (PCE), the request including the request including: a label that identifies spectrum to be restricted from use in the path; and a channel spacing field; and receiving, by the PCC and from the PCE, a response to the request, the response including an identifier of an assigned path on the flexi-grid network.

摘要： A first telecommunications edge cloud (TEC) element deployed between a client and a packet network includes a TEC hardware layer including storage resources, networking resources, and computing resources, wherein the computing resources include a plurality of processors. The networking resources are configured to transmit a first general update message to a plurality of second TEC elements within a federation, transmit a first application-specific update message to the second TEC elements within the federation, and receive a plurality of second update messages from the second TEC elements that are associated with the federation. The federation includes the second TEC elements and the first TEC element and shares resources to provide data and services to a requesting client. The storage resources are coupled to the computing resources and the networking resources and configured to store a second generic resource container and second application-specific resource container for each of the second TEC elements.
