Zusammenfassung:Reassembly of member cells into a packet comprises receiving an incoming member cell of a packet from a switching fabric wherein each member cell comprises a segment of the packet and a header, generating a reassembly key using selected information from the incoming member cell header wherein the selected information is the same for all member cells of the packet, checking a reassembly table in a content addressable memory to find an entry that includes a logic key matching the reassembly key, and using a content index in the found entry and a sequence number of the incoming member cell within the packet, to determine a location offset in a reassembly buffer area for storing the incoming member cell at said location offset in the reassembly buffer area for the packet for reassembly.
