KUPF: 2-phase selection model of classification records

Abstract

With the advance of computing and inter-networking technologies, various services, which need classification of data, are provided. Firewall and QoS control are typical services which classify the data flow. These services are based on two or more rules, and select a rule to classify the data. However, some of their rules may conflict with one another and it is necessary to resolve the conflicts in these classification mechanisms. In this paper, we discuss the classification of data with the generalization of the parameter filter. Then we arrange the parameter filter and propose a 2-phase selection model of classification records. In this model, we consider the procedure of the parameter filter as the phase depending only on the schema of the filter rule and the phase depending on the service. We also implement the KUPF framework based on this model and a sample service which provides QoS control over IPv4/IPv6 network. With this sample implementation, we validate the availability and evaluate the performance of KUPF.
