Abstract
A load balancer in a communication network tracks active network flows using a Bloom filter and takes a snapshot of the Bloom filter at the time of a scaling event. The load balancer uses the Bloom filter snapshot to differentiate packets belonging to pre-existing network flows from packets belonging to new network flows. Packets belonging to pre-existing network flows continue to be distributed according to a mapping function in use prior to the scaling event. Packets belonging to new network flows are distributed according to a new mapping function.
