Abstract: This disclosure pertains to augmenting metadata of a packet destined for service function chaining with application identifier information. The application identifier information can be added to the metadata of a packet service header (or, more specifically, a network service header). The packet can be exported to a statistics collector that can correlate statistical information about the application with statistical information about service functions applied to the packet, as well as other statistical information.

Abstract: In one embodiment, a method includes receiving a trace request packet at a service node on a service chain, the trace request packet comprising a service index limit that remains constant for use in identifying at least one service node in the service chain to generate a trace report packet, and processing the trace request packet and determining whether to forward the trace request packet on the service chain or to generate the trace report packet based on a comparison of a service index to the service index limit in the trace request packet, wherein the trace report packet includes service function information of a plurality of service functions in the service chain, and the trace request packet is forwarded on the service chain according to a service path identifier and the service index.

Abstract: Techniques are provided to programming network analytics processing in virtual and physical network devices, useful for software-defined networking (SDN). A controller, e.g., a so-called SDN controller, is configured to identify a control-plane or data-plane flow originating, terminating or transiting a physical or virtual network element. The controller generates one or more network analytics processing actions to be performed by the physical or virtual network element based on inspection of traffic by the physical or virtual network element. The controller forms or generates an inspect/apply-action message containing information identifying the control-plane or data-plane flow for inspection and the one or more network analytics processing actions to be performed. The inspect/apply-action message is sent to the physical or virtual network element.

Abstract: Embodiments are directed to receiving an original packet at a service function; determining, for a reverse packet, a reverse service path identifier for a previous hop on a service function chain; determining, for the reverse packet, a service index for the reverse service path identifier; and transmitting the reverse packet to the previous hop on the service function chain.

Abstract: A packet is received at a network device hosting a service function that is part of a service chain. The packet is sent to the network device from an originating network device. The content of the packet is analyzed to determine that the packet comprises a request for statistical values to be aggregated by the network device. The statistical values are aggregated at the network device. A report comprising the statistical values aggregated at the network device is generated. The report is sent to the originating network device.
