Two versions of the Internet (IP) router-table problem are considered. In the first, the router table consists of n pairs of tuples of the form (p, a), where p is an address prefix and a is the next-hop information. In this version of the router-table problem, we are to perform the following operations: insert a new tuple, delete an existing tuple, and find(More)
We develop an enhanced interval tree data structure that is suitable for the representation of dynamic IP router tables. Several refinements of this enhanced structure are proposed for a variety of IP router tables. For example, the data structure called BOB (binary tree on binary tree) is developed for dynamic router tables in which the rule filters are(More)
We propose a data structure–dynamic tree bitmap–for the representation of dynamic IP router tables that must support very high lookup and update rates. In fact, the dynamic tree bitmap is able to support updates at the same rate as lookups and is very competitive with other structures–tree bitmap and BaRT–proposed earlier for dynamic tables. Although the(More)
Plant hormones are small organic molecules that influence almost every aspect of plant growth and development. Genetic and molecular studies have revealed a large number of genes that are involved in responses to numerous plant hormones, including auxin, gibberellin, cytokinin, abscisic acid, ethylene, jasmonic acid, salicylic acid, and brassinosteroid.(More)
We review the data structures that have been proposed for one-dimensional packet classification. Our review is limited to data structures for the case when ties among the rules that match an incoming packet are broken by selecting the matching rule that is most specific. For the case when the rule filters are destination-address prefixes or are(More)
Two schemes—prefix partitioning and interval partitioning—are proposed to improve the performance of dynamic IP router-table designs. While prefix partitioning applies to all known dynamic router-table designs, interval partitioning applies to the alternative collection of binary search tree designs of Sahni and Kim [16].
