A Novel Scalable IPv6 Lookup Scheme Using Compressed Pipelined Tries
An IP router has to match each incoming packet’s IP destination address against all stored prefixes in its forwarding table. This task is increasingly more challenging as the routers have to: not only keep up with the ultra-high link speeds, but also be ready to switch to the 128-bit IPv6 address space while the number of prefixes grows quickly. Commercially, many routers employ Ternary Content...
متن کاملMobility after Apprenticeship { How Eeective Is the German Apprenticeship System ?
In this paper we provide evidence on the eeectiveness of the German apprenticeship system as a means to enhance workers productivity. More speciically, we estimate earnings diierentials between those who subsequently leave the occupation they were apprenticed in and those who remain in their training occupation. Some authors have been concerned with the potential productivity{ and earnings-decr...
متن کاملUncommon Suffix Tries
Common assumptions on the source producing the words inserted in a suffix trie with n leaves lead to a lnn height and saturation level. We provide an example of a suffix trie whose height increases faster than a power of n and another one whose saturation level is negligible with respect to lnn. Both are built from VLMC (Variable Length Markov Chain) probabilistic sources and are easily extende...
متن کاملUpdating Reduced Implicate Tries
The reduced implicate trie, introduced in [11], is a data structure that may be used as a target language for knowledge compilation. It has the property that, even when large, it guarantees fast response to queries. Specifically, a query can be processed in time linear in the size of the query regardless of the size of the compiled knowledge base. The knowledge compilation paradigm typically as...
متن کاملReduced Implicant Tries
The goal of knowledge compilation is to enable fast queries. Such queries are often in the form of conjunctive normal form (CNF) clauses, and the query amounts to the question of whether the clause is implied by the knowledge base. Here, we consider the dual type of query which is a DNF clause; the query then amounts to the question of whether the knowledge base is implied by the clause. Prior ...
