“…Hence, there have been active researches on algorithmic RAM-based IP lookup methods. There are 3 major approaches for algorithmic IP lookup methods, namely, trie-based methods [3,5,6,7,9,13,17], range search methods [2,14,16], and hashing-based methods [1,12]. In this paper, we shall present the design of a hardware IP lookup engine using multi-level index tables, where the index tables are derived based on a modified binary-trie structure called the bit-shuffled trie.…”
