Abstract
A device may include two or more line interfaces. One of the line interfaces may include a component to buffer a packet that is received at the line interface, perform a lookup of information related to selecting a flow based on a header of the packet, apply a symmetric hash function to addresses in the header to obtain a hash when the information related to selecting the flow indicates the flow is to be selected based on a random method, compare the hash to a particular number using the information related to selecting the flow, the particular number being same for the line interfaces, sample a flow when the hash matches the particular number, create a flow record for the flow, and sample packets based on the flow record.
