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.
