Abstract: In one embodiment, a service chain data packet is instrumented as it is communicated among network nodes in a network providing service-level and/or networking operations visibility. The service chain data packet includes a particular header identifying a service group defining one or more service functions, and is a data packet and not a probe packet. A network node adds networking and/or service-layer operations data to the particular service chain data packet, such as, but not limited to, in the particular header. Such networking operations data includes a performance metric or attribute related to the transport of the particular service chain packet in the network. Such service-layer operations data includes a performance metric or attribute related to the service-level processing of the particular service chain data packet in the network.

Abstract: In one implementation, a method herein comprises: determining a given time during which a computer network is unstable in response to a topology event within the computer network; causing, in response to the computer network being unstable, a measurement analysis process to perform network performance analysis on the computer network based on the computer network being unstable during the given time; and causing, in response to determining that the computer network is otherwise in a stable state, the measurement analysis process to perform network performance analysis on the computer network based on the computer network being stable.

Abstract: In one embodiment, Segment Routing Internet Protocol Version 6 (SRv6) micro segments (“uSIDs”) are included in destination addresses, and possibly in other Segment Identifiers (“SIDs”), of packets transported through a network, and invoking corresponding network behavior, including, but not limited to, realization of corresponding network slices. In one embodiment, network nodes are configured to perform differential network slice realization functionality based on values slice-representative value(s) provided by global and/or local uSIDs of packets. This configuration may be defined by a controller in the network and/or routing protocol advertisements. Responsive to a received packet, a network node identifies and performs the corresponding network slice realization functionality based on slice-representative value(s) provided by one or more global and/or local uSIDs of the destination address of the received packet. Various encodings within an IPv6 Destination Address of the encapsulating packet are disclosed.
