Algorithmic Approaches to Optimizing TCAM-Based Packet Classification
Packet classification is the core mechanism that enables many networking services such as packet filtering and traffic accounting. Using Ternary Content Addressable Memories (TCAMs) to perform high-speed packet classification has become the de facto standard in industry because TCAMs can facilitate constant time classification by comparing a packet with all rules of ternary encoding in parallel...

متن کاملFPGA Based Architecture for High Performance SRAM Based TCAM for Search Operations
Ternary Content Addressable memory is a type of memory that allows the memory to be searched by content rather than by address. It performs high speed lookup operations within a single clock cycle. But when compared to RAM technology the conventional TCAM circuitry has certain limitations such as low access time, low storage capacity, circuit complexity and high cost. So we can use the benefits...
متن کاملFast Regular Expression Matching Using Small TCAMs for Network Intrusion Detection and Prevention Systems
Regular expression (RE) matching is a core component of deep packet inspection in modern networking and security devices. In this paper, we propose the first hardware-based RE matching approach that uses Ternary Content Addressable Memories (TCAMs), which are off-the-shelf chips and have been widely deployed in modern networking devices for packet classification. We propose three novel techniqu...
متن کاملOn a trie partitioning algorithm for power-efficient TCAMs
Internet routers conduct routing table (RT) lookup based on the destination IP address of the incoming packet to decide which output port to forward the packet. Ternary content-addressible memories (TCAM) uses parallelism to achieve lookup in a single cycle. One of the major drawbacks of TCAM is its highpower consumption. Trie-based architecture has been proposed to reduce TCAM power consumptio...
