Abstract
An approach for managing the consumption of resources uses adaptive random sampling to decrease the collection of flow statistical data as the consumption of resources increases. When a packet is received from a network, a determination is made whether the packet belongs to an existing flow, for which flow statistical data is being collected, or to a new flow. If the packet belongs to an existing flow, then the flow statistical data for the existing flow is updated to reflect the packet. If the packet belongs to the new flow, then a sampling probability is used to determine whether the new flow is to be sampled. The sampling probability is determined, at least in part, upon a current usage of resources.
