IMPLEMENTING PACKET CLASSIFICATION USING STANDARD ACL
Abstract
Packet classification involves the categorization of packets within network systems, such as firewalls and routers, based on their flow. Its primary objective is to match packet headers with a predefined set of filters. In this research, we propose a system that utilizes the source IP address of each incoming packet for packet classification. By employing a rule set, the system can determine whether to grant or deny access to each packet. The algorithm examines the source IP address header field of received packets on a specific link and compares it against a collection of rules. It then outputs the action associated with the highest priority rule that corresponds to the packet header. Ultimately, the classification of individual packets is based on the action specified in the rule set.
