Abstract: In some examples, an example method to measure quality of service (QoS) of a network tunnel may include configuring a network tunnel from a tunnel source endpoint to a tunnel destination endpoint, transmitting multiple status packets to the tunnel destination endpoint, receiving multiple forwarded status packets from the tunnel destination endpoint, determining a time of receipt of each of the forwarded status packets, and determining a QoS measure of the network tunnel based on a time of transmission of each of the multiple status packets and the time of receipt of each of the forwarded status packets.

Abstract: In general, this disclosure describes techniques for applying, with a network device, subscriber-specific packet processing using an internal processing path that includes service objects that are commonly applied to multiple packet flows associated with multiple subscribers. In one example, a network device control plane creates subscriber records that include, for respective subscribers, one or more variable values that specify service objects as well as an identifier for a packet processing template. A forwarding plane of the network device receives and maps subscriber packets to an associated subscriber record and then processes the packet by executing the packet processing template specified by the subscriber record. When the forwarding plane reaches a variable while executing the specified packet processing template, the forwarding plane reads the associated variable value from the subscriber record to identify and then apply the subscriber-specific service object specified by the variable.
