Use of Cuckoo Filters with FD.io VPP for Software IPv6 Routing Lookup.

The filter technologies, e.g., Bloom filters, have been used for IP lookup for their compactness and efficiency. We investigate the performance of cuckoo filters with Cisco's VPP (Vector Packet Processing) for IP lookup. We also introduce a variant called a length-aware cuckoo filter that treats incoming IP addresses discriminatively, and study its performance with VPP. As proof-of-concept, we implement cuckoo filters with VPP, and test them on both functions and performance with focus on the ip6-input node in VPP.
