Abstract:Hash tables (HTs) are poorly designed for multiple memory accesses during IP lookup and this design flow critically affects their throughput in high-speed routers. Thus, a high capacity HT with a predictable lookup throughput is desirable. A recently proposed fast HT (FHT) [20] has drawbacks like low on-chip memory utilization for a high-speed router and substantial memory overheads due to off-chip duplicate keys and pointers. Similarly, a Bloomier filter-based HT (BFHT) [13], generating an index to a key tabl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
