PINNING SERVICE FUNCTION CHAINS TO CONTEXT-SPECIFIC SERVICE INSTANCES

摘要

Pinning service function chains to specific points of execution (e.g., service instances) in a network system may be provided. Available service instances may be solicited from service hosts. The service hosts may be exposed under a context identifier (e.g., a slicing identifier or a device identifier). A subset of the available service instances may be selected to serve a client. The client may be identified by a client- specific identifier. The selected service hosts may be instructed to register the selected service instances under a name that ties the client identifier and the service function identifier into a singie name. The client may use the single name to initiate a service function chain. Service function instances may initiate a next hop in the named service function chain through using the client identifier derived from an incoming request.
