  1. Wire Speed Packet Classification Without TCAMs: A FewMore Registers (And A Bit of Logic) Are Enough Author: Qunfeng Dong, Suman Banerjee, Jia Wang, Dheeraj Agrawal Publisher: SIGMETRICS’ 07 Presenter: Fang-Chen, Kuo

  2. Motivation Cache Rules ! Evolving rules

  3. Cache Evolving rules • Hit ratio ↑ with less cache entries. • Without using TCAM

  4. Architecture

  5. Classification Scheme (SPDD)

  6. Cache Manager (Regular Hyper-Cube List)

  7. Rule Expanding

  8. Hardware Design of Rule Cache

  9. OPTIMIZATION (1/2) - PPDD (Pruned Packet decision Diagram)

  10. OPTIMIZATION (2/2) – Ordering Packet Header Fields

  11. Evaluation (1/6) • We evaluate the performance of our smart rule cache using 4 real traffic traces and 10 real rule sets obtained from a tier-1 ISP backbone network. • The decision of rules is either permit or deny.

  12. Evaluation (2/6)-Memory Requirement The default ordering is: (1) source IP address; (2) destination IP address; (3) source port; (4) destination port; (5) protocol type. • The best ordering is: • protocol type; • source IP address; • (2) destination IP address; • (3) source port; • (4) destination port.

  13. Evaluation (3/6)

  14. Evaluation (4/6)–Cache Miss Ratio

  15. Evaluation (5/6) – Sampling Interval

  16. Evaluation (6/6) –Result for Complicated Rule Sets
