Abstract: In one embodiment, a receiver device determines that it accepts flow entropy, and accordingly determines a set of entropy labels the receiver device is accepting. After transmitting the set of entropy labels from the receiver device to one or more sender devices, the receiver device may then receive packets from the one or more sender devices with selected particular entropy labels from the set of entropy labels. In another embodiment, a sender device receives from a receiver device a set of entropy labels the receiver device is accepting. As such, when determining a packet to forward to the receiver device with flow entropy, the sender device may select a particular entropy label from the set of entropy labels for that receiver device, and transmits the packet device to the receiver device with the selected particular entropy label.

Abstract: In one embodiment, a device samples actual service traffic at a device in a computer network, and generates real-time statistics on distribution of various packet header parameters of the sampled traffic that influence forwarding in the computer network. As such, the device may generate and transmit synthetic measurement traffic according to the distribution. For instance, in one embodiment, the synthetic traffic may be a replay of actual service traffic with an indication that the replayed traffic is synthetic, while in another embodiment, newly generated synthetic measurement traffic may have packet header parameters substantially matching the sampled traffic.
