Abstract
A network device receives, via a forwarding path, a sequence of packets, where each of the packets includes a sequence number. The network device extracts the sequence numbers from the sequence of packets, records the extracted sequence numbers, and determines a first number of packets of the sequence of packets that have been dropped on the forwarding path based on the extracted sequence numbers. The network device determines a traffic dropping ratio for the forwarding path based on the first number of the packets of the sequence of packets that have been dropped on the forwarding path.
