Title

PCAM-BASED WIRE-SPEED MULTIDIMENSIONAL PACKET CLASSIFICATION

Abstract

Packet classification is the process of categorizing packets according to a given Rule Database. Building large high-speed multi-field packet classifiers is an acknowledged challenge to researchers. Although the rules specify ranges, IP prefixes and wildcards, current classifiers inefficiently search a range as multiple prefixes. The present paper deals with a part of the total packet classification problem. Specifically, it proposes a generalized hardware-specific wire-speed direct search technique for ranges and wildcards but not IP prefixes. The proposed hardware is basically a pipelined content-addressable or associative memory (PCAM or PAM), based on a pipelined content-to-address memory (PCTAM). Prior to performing the high-speed pipelined associative search, some preprocessing of the Rule Database is done to build an associative search table. Since it uses only commercial RAM arrays with a few simple processing elements, the PAM is likely to offer a better alternative, in respect of cost, capacity and power consumption, to ternary CAM (TCAM) which is often used in high-speed packet classifiers. The proposed range-based search engine has a constant search time of about two memory access times, independent of the size of the Rule Database and the width of the field values and, thus, may prove attractive for use as a component in large high-speed multidimensional packet classifiers.
