Parallel Bloom filter is a multi-field query structure which possess high query efficiency and less resource consumption. In this paper, we propose masked parallel Bloom filter with twice verification Hash table (MPBF-TVHT) to achieve full flexibility of multi-protocol query and lower false positive possibility (FPP) for SDN switch. We depict item store and query process of multi-protocol lookup table in all field combinations, analysis influence that different combinations have on FPP and provide effective solutions. Simulation and practical test prove the proposed structure to support adequate table entries while keeping a low FPP for SDN switch.Keywords-Parallel Bloom filter, Software Defined Networking, multi-field query, low false positive.
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.
