WebMar 21, 2024 · The main idea is to use a space-efficient probabilistic data structure called Cuckoo filter (CF) [ 4] integrated with an extended node tree (X-tree) [ 5] for many-field packet classification. Our choice of X-tree came from that the X-tree has high query performance. This is because the following reasons: 1. WebMay 22, 2024 · Support Optimality and Adaptive Cuckoo Filters. Filters (such as Bloom Filters) are data structures that speed up network routing and measurement operations by storing a compressed representation of a set. Filters are space efficient, but can make bounded one-sided errors: with tunable probability epsilon, they may report that a query …

WebCuckoo filters are based on cuckoo hashing. A Cuckoo filter is essentially a cuckoo hash table which stores each key's fingerprint. As Cuckoo hash tables are highly compact, a cuckoo filter often requires less space than conventional Bloom filters for applications that require low false positive rates (< 3%).
