    Abstract: Many researches are about optimizing schemes for packet classification and matching filters to increase the performance of many network devices such as firewalls and QoS routers. Most of the proposed algorithms do not process dynamically the packets and give no specific interest in the skewness of the traffic. In this paper, we conceive a set of self-adjusting tree filters by combining the scheme of binary search on prefix length with the splay tree model. Hence, we have at most 2 hash accesses per filter for consecutive values. Our proposed filter is adapted to easily assure exact matching for protocol field, prefix matching for IP addresses, and range matching for port numbers. Also, we use the splaying technique to optimize the early rejection of unwanted flows, which is important for many filtering devices such as firewalls.

    Abstract: Many schemes of high-performance IP address lookup have been proposed recently. But most of them do not process dynamically the packets and give no specific interest in the skewness of the traffic. Hence, the lack of dynamic packet routing algorithms has been the motivation for this research. In this paper, we have conceived a self-adjusting tree filter, by combining the scheme of binary search on prefix length with the splay tree model. Consequently, we have at most 2 hash accesses for all consecutive values. We give also a special interest in the amount of packets treated then routed through the default route entry. Those packets present an important part of the traffic treated by the routers and they might cause more harm than others as they traverse a long decision path before they are finally sent to the default route.
