GigaHash: scalable minimal perfect hashing for billions of urls
A minimal perfect function maps a static set of keys on to the range of integers {0,1,2, ... , - 1}. We present a scalable high performance algorithm based on random graphs for ...

SUSE: superior storage-efficiency for routing tables through prefix transformation and aggregation
Abstract--A novel storage design for IP routing table construction is introduced on the basis of a single set-associative hash table to support fast longest prefix matching (LPM). ...

CARD: Compact And Real-time Descriptors
We propose Compact And Real-time Descriptors (CARD) which can be computed very rapidly and be expressed by short binary codes. An efficient algorithm based on lookup tables is pr...

Weaknesses of Cuckoo Hashing with a Simple Universal Hash Class: The Case of Large Universes
Cuckoo hashing was introduced by Pagh and Rodler in 2001 [12]. A set S of n keys is stored in two tables T1 and T2 each of which has m cells of capacity 1 such that constant access...

Burst tries: a fast, efficient data structure for string keys
Many applications depend on efficient management of large sets of distinct strings in memory. For example, during index construction for text databases a record is held for each d...
