Abstract
Technologies for managing lookup tables are described. The lookup tables may be used for a two-level lookup scheme for packet processing. When the tables need to be updated with a new key for packet processing, information about the new key may be added to a first-level lookup table and a second-level lookup table. The first-level lookup table may be used to identify a handling node for an obtained packet, and the handling node may perform a second-level table lookup to obtain information for further packet processing. The first lookup table may be replicated on all the nodes in a cluster, and the second-level lookup table may be unique to each node in the cluster. Other embodiments are described herein and claimed.
