  1. M. Ilvesmäki and J. Karvo, On the Behavior of the Candidate Table of the Per-Flow Packet Count Flow Classifier, in Technical Proceedings, 8th IFIP Workshop on the Performance Modelling and Evaluation of ATM & IP Networks(ATM & IP 2000), Networks UK Publishers, 2000 (pdf)(bib)
    Abstract: We study the behavior of the flow candidate table of the packet count flow classifier. Use of the packet count flow classifier has been suggested for several technical implementations of flow classification. The previous studies have concentrated e.g. on observing workload reduction of packet forwarding in an Internet router. We will observe the consequences of implementing a packet count classifier. To realize a packet count classifier, an additional candidate table is needed, where information on flow candidates is kept. More specifically, we will observe the temporal and distributional behavior of the flow candidate table size using actual traffic traces and point out the requirements for the actual implementation of the flow classifier. The results show that the size of the candidate table varies significantly depending on the network and classifier parameters. Also, the candidate table size changes constantly, and fast entry creation and deletion are needed.
