Abstract
A method has provides a router having an input, an output, and a shared memory. The router also has a forwarding path to forward a plurality of packets from the input to the output, and a service path to manage statistical data relating to packets forwarded through the forwarding path. The forwarding path has a counter to count aggregate packet information relating to the plurality of packets it forwards. Next, the method counts, using the counter(s), aggregate packet information relating to the packets forwarded through the forwarding path to produce count information. After producing the count information, the method uses the forwarding path to store the count information in the shared memory of the router, and then causes the service path to retrieve the count information from the shared memory. The service path ultimately produces statistical information using the count information retrieved from the shared memory.
