Abstract

See full text

In one embodiment, a device in a computer network receives a particular packet associated with a transmission attempts value, the associated transmission attempts value indicative of a first number of times a transmitter has attempted to transmit the particular packet. In response, the device increases by one a stored successful attempts value stored at the device, the stored successful attempts value indicative of a second number of times the device has received the same particular packet. As such, a reachability rate of a link from the transmitter to the device may be determined based on comparing the associated transmission attempts value to the stored successful attempts value.
