Abstract
Packet forwarding includes creating a first lookup table for mapping packets to nodes based on the number of nodes in a first set of nodes. A received packet is mapped to a mapping value using a predetermined mapping function. The first lookup table is indexed using a first subset of bits comprising the mapping value. A second lookup table is created in response to adding a node to the first set of nodes. A subsequently received packet is mapped to a mapping value using the same predetermined mapping function to index the second lookup table using a second subset of bits comprising the mapping value.
