Port Block Allocation for Network Address Translation
This term project aims to study the issue of the Carrier-Grade NAT (CGN) technique, which has to create log messages with address translation for every new connection. Because the CGN is stationed between large networks, it may daily record hundreds of thousands of connections. This amount of records have high memory requirements and even more difficult is to search for a specific log record. These problems solve the port block allocation for address translation. The output of this work is the creation of a rule in the iptables that performs this port block allocation for address translation. It consists of a user part that processes the rules and a kernel module that implements the functionality of the rule.
