Abstract
In a computer network, a method of random sampling of network packets is provided including the steps of providing a network switch, providing a monitoring device, the monitoring having a memory and a data storage unit, providing a network interface to connect the network switch to the monitoring switch, selecting a reference error check code value in the monitoring device, receiving a first network packet from the network switch, comparing, in the network monitoring device, the reference error check code with an error check code of a first network packet, storing the first network packet in the monitoring device if the error check code value of the first network packet matches the reference error check code of the first network packet, and repeating the steps of receiving, comparing and storing for subsequent network packets. In such a method, the reference error check value may be selected from a first network packet, or from one of any of the plurality of network packets received, whether previous to or subsequent to, any particular received network packet.
