Abstract: Methods, apparatus, systems, architectures, and interfaces for a path computation element (PCE) performing run-time operations for providing isolated service chains in a name-based routing system of communications network, are provided. A method may include any of: receiving, from a client device, a first message requesting a forwarding identifier (FID) associated with a fully qualified domain name (FQDN) of a service function (SF), the first message including information indicating: (1) a first identifier (ID) associated with the FQDN of the SF, and (2) a second ID associated with the FQDN of the SF; on condition that the PCE has determined that the first ID is for a subscriber associated with a namespace known to the PCE, determining the FID associated with the FQDN of the SF according to namespace information; and transmitting information associated with the FID to the client device.

Abstract: A method, implemented by a wireless transmit/receive unit, WTRU, includes receiving, a first message including information indicating a control plane procedure. According to the control plane procedure, a second message including a publish request is transmitted to a network node. Responsive to the publish request, a third message including information indicating a packet path routing indication is received from the network node. A fourth message, including uplink data, according to the packet path routing indication is transmitted to a data network.

Abstract: System and methods are described to register FQDN-based IP service endpoints at network attachment points. One embodiment takes the form of a method comprising: receiving, at a server-side network access point (sNAP) in an information-centric network (ICN), a registration request including a first fully qualified domain name (FQDN), a port, a transport protocol, and a service name of an IP server; publishing, at the sNAP, the port, the transport protocol, and the service name to a first content identifier (CID); and subscribing, at the sNAP, to a second CID that is based on the FQDN.

Abstract: An example device may determine a fully qualified domain name (FQDN) using a service operation, a producer identifier, and a parent domain, wherein the service operation is associated with a network function, and wherein the producer identifier identifies a producer device that provides the service operation; generate a target address using the FQDN and an event name, wherein the event name indicates a network function event: send a request message to the producer device using the target address, wherein the request message indicates a request to subscribe to the service operation for the network function event; receive a confirmation message from the producer device, wherein the confirmation message indicates that the device is subscribed to the service operation for the network function event; and receive an event message from the service operation provided by the producer device, wherein the event message indicates that the network function event has occurred.

Abstract: An edge termination point (ETP) transport protocol between two or more ETPs in a network, such as a Layer 2 transport network, may be provided. A device may receive an incoming internet protocol (IP) transaction at an edge termination point (ETP) in a network. The device may terminate the received incoming IP transaction at the ETP. The device may map the terminated incoming IP transaction onto an ETP-to-ETP communication. The device may control the ETP-to-ETP communication. For example, the device may control the ETP-to-ETP communication based on a resource management regime. The device may map the ETP-to-ETP communication onto one or more outgoing IP transactions at the ETP. The device may map the IP transaction onto an ETP-ETP communication. The ETP-ETP communication may include one or more ETP flows and one or more ETP transactions.

Abstract: Method, apparatus, and systems for transparent switching of service function identifiers in wireless communications are provided. In an example, a method for wireless communications comprises sending configuration information to one or more Service Function Endpoints (SFEs) using a programmable application programming interface (API), implementing the API as a programmable middleware, and registering each of the one or more SFEs with a respective identifier according to a service description at the programable middleware.
