Claim 0:
1. A method comprising:
receiving, at a device, a packet including a request for network state information;
generating, at the device, one or more temporal congestion signals;
adding, at the device, the one or more temporal congestion signals to the packet; and
transmitting, at the device, the packet including the one or more temporal congestion signals, wherein:
generating the one or more temporal congestion signals comprises generating at least a line busyness signal based on a duration of a busy period of the device; and
generating the line busyness signal based on the duration of the busy period of the device comprises:
if the device has one or more items in a queue of the device, generating the line busyness signal based on a difference between an arrival time of the packet and a start time of the busy period of the device; and
if the device has no items in the queue of the device, generating the line busyness signal based on a difference between a start time of an idle period of the device and the start time of the busy period of the device.
