Abstract: An upstream service function forwarder (SFF) node including a receiver configured to receive a packet, a processor operably coupled to the receiver and configured to implement a load distribution function (LDF), wherein the LDF is configured to select one of a plurality of service functions (SFs) of a same type on a downstream SFF node to process the packet, and a transmitter operably coupled to the processor and configured to transmit the packet to the downstream SFF node for processing by the one of the plurality of SFs selected.

Abstract: The disclosure relates to technology for coordinating execution of serverless functions. One or more events are received from one or more event sources. The one or more events are mapped to one or more event states of a function graph according to a mapping rule, the one or more event states including one or more actions, and the one or more actions which satisfied the mapping rule are executed. The received events are sent to a computer system to trigger the computer system initiating one or more computing resource groups for executing one or more serverless functions associated with the one or more actions. One or more responses are received from the serverless functions.

Abstract: A novel scheme is defined for supporting service graphs to allow specific service functions to be applied to selected subsets of packet flows. According to one or more embodiments, a service graph is modeled as chains or sequences of “flow steering entities” and “service instances.” According to an embodiment, a flow steering entity (FSE) is configured to identify the flow, and select the next hop service instance in the chain. After a service instance returns the flow packet, the FSE steers the packet to the next FSE in the graph. An initial FSE is used to select matching traffic to enter the service graph. Wherever path forking and merging is required in the service graph, additional classifiers are positioned with the FSE to steer a subset of traffic along different paths of service function instances.
