The network element has a cache memory in which cache entries represent a portion of addresses stored in a main memory, The destination address and the cache entries each comprise a binary number. A hash function is applied to the masked destination address to access a hash table. When the number of most significant bits corresponding to the value in the hash table in one of the cache entries and in the destination address are identical, routing information for the packet is retrieved from the cache entry."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hash table-based mask length computation for longest prefix match caching","description":"A data packet is received in a network element.
