Title: Generating searchable data entries and applications therefore
Inventor: ABDAT MOURAD
IPC: G11C15/00
Filed: 1999-11-30
Abstract: New techniques for generating entries in a content addressable memory (CAM) capable of comparison operations such as "greater than" and "less than" decisions are described. The techniques can be used with binary or ternary CAMS. The number of CAM entries needed to implement such decisions is drastically reduced for both binary and ternary CAMS. In the case of binary CAMS, one or multiple searches are needed to perform the comparisons, while in the case of ternary CAMS a tradeoff between the number of CAM entries and the number of searches can be found. As an example, a method of classifying data networking packets is implemented using the new techniques. A packet classifier based on subfields of a packet header is also described.
