Abstract: In one embodiment, a Segment Routing network node provides efficiencies in processing and communicating Internet Protocol packets in a network. This Segment Routing node typically advertises (e.g., using Border Gateway Protocol) its Segment Routing processing capabilities, such as Penultimate Segment Pop (PSP) and/or Ultimate Segment Pop (USP) of a Segment Routing Header (including in the context of a packet that has multiple Segment Routing Headers). Subsequently, an Internet Protocol Segment Routing packet having multiple Segment Routing Headers is received. The packet is processed according to a Segment Routing function, with is processing including removing a first one of the Segment Routing Headers and forwarding the resultant Segment Routing packet. The value of the Segments Left field in the first Segment Routing Header identifies to perform PSP when the value is one, to perform USP when the value is zero, or to perform other processing.

Abstract: In one embodiment, segment routing (SR) network processing of packets is performed on packets having a segment identifier structure providing processing and/or memory efficiencies. Responsive to an identified particular segment routing policy, the particular router retrieves from memory a dynamic segment routing identifier portion of the particular SR policy that includes a SR node value and a SR function value. The SR function value identifies segment routing processing to be performed by a router in the network identified based on the SR node value. A segment routing discriminator is independently identified, possibly being a fixed value for all segment identifiers in the network. Before sending into the network, a complete segment identifier is added to the particular packet by combining the segment routing discriminator with the dynamic segment routing identifier portion. The particular packet including the complete segment identifier is sent into the network.

Abstract: In an embodiment, a method comprises receiving, at an analytics engine, from a separate analytics application, an analytics query for data that is potentially available in data streams of networked computing devices; sending, to a distributed network analytics controller, sub-queries based on the analytics query; determining distributed network analytics agents capable of executing each of the sub-queries; sending instructions to the agents to initiate the sub-queries for the data at specified locations; initiating execution of the sub-queries on data streams that are locally available at one of the networked computing devices at which the agents are running; forming summarized data streams and zero or more raw data streams at the networked computing devices having the analytics agents; sending the summarized data streams and the zero or more raw data streams to the analytics engine; wherein the method is performed by computing device(s).
