This paper proposes an efficient IP address lookup algorithm based on a small balanced tree using entry reduction. The leaf-pushing is used for constructing the balanced tree. Then, the search tree is minimized by the use of a new entry reduction method.

Abstract: This paper deals with the traditional IP address lookup problem with fast updates. We propose a B-tree data structure, called MMSPT (Multiway Most Specific Prefix Tree), which is constructed by using the most specific prefixes in routing tables.
The trie/tree-based is a popular class of IP lookup IP address lookup algorithms can be An efficient IP address lookup algorithm based on a small balanced tree using entry reduction.
Efficient IP lookup using hybrid trie-based partitioning of TCAM-based open flow switches. For a given IP address, it compares each and every entry present in the particular bucket. The output of the matched entry can be mapped to find the next hop. Every group is a balanced search tree …
Abstract: IP address lookup operation determines the longest prefix matching each incoming destination address. As a fundamental operation for packet forwarding at Internet routers, search speed for routing table lookup is the most important performance metric.

Comparing with the best existing dynamic routing table algorithm, PBOB (Prefix Binary tree On Binary tree), our experiment results using the real routing tables show that the proposed scheme performs better than PBOB in terms of the lookup speed, insertion time, deletion time, and memory requirement.
2.1 Trie-based IP Lookup The entries in the routing tables are speciﬁed using pre-ﬁxes, and the nature of IP lookup is longest preﬁx matching (LPM). The most common data structure in algorithmic so-lutions for LPM is some form of trie . A trie is a binary tree, where a preﬁx is …

• Algorithm to minimize average lookup time while keeping worst case bounded: of independent interest in information theory. • Hardware lookup algorithm: first proposed algorithm that performs a routing lookup in one memory access.
describe a modified algorithm that not only balances but also threads binary search trees, and then tackle the problems of maintaining such a data structure. Since the algorithm is essentially based on the previous tree-balancing algorithm, and the portion dealing with
The heap based algorithm’s complexity would be O(N log N + K). Consider the following alternative. Plunk the numbers in an array, and for each query, run the linear selection algorithm (using the quicksort pivot, say). Now you have an algorithm with running time O(K N).
