Apparatus and method for storing min terms in network switch port memory for access and compactness

摘要: A network switch, configured for performing layer 2 and 3 switching in an Ethernet (IEEE 802.3) without blocking of incoming data packets, includes a switch port having filter (i.e., packet classifier module) evaluating on instantaneous basis. The processor interface receiving plurality templates simultaneous comparison respective formats packet. Each template is composed min terms, wherein each term specifies prescribed operation within selected byte the may be programmed by user stored internal memory. controller controls storage terms memory determining corresponding relevance evaluation stores blocks based to In event that group exceed capacity block, excess user-defined field. related location block field, second shared
