US 2004/0073704 A1 · Intelligent network address translator and methods for network address translation

Abstract

An intelligent network address translation system and methods for intelligent network address translation. The invention analyzes all data packets being communicated between the private address relam and the public address realm and performs a predefined mode of network address translation based on the packet type. By analyzing every packet that the network encounters and adjusting the network address translation mode based on the packet type, the system and method of the present invention is able to adjust the mode of network address translation dynamically during a network user's ongoing network session. Additionaly, by basing which mode of translation will be employed based on packet type the translation method of the present invention insures that IP addresses are distributed efficiently and distribution of the amount of addresses is minimized.

Dependent claims

A method for network address translation in a communication network, the method comprising:

determining a data packet type for a data packet being communicated from private hosts to public network services, the data packet having a private network address;
determining if the data packet type requires assigning an IP address from available public IP addresses;
assigning the data packet an IP address from the available public IP addresses if a determination is made that the packet type requires such;
translating the private network address of the data packet to the assigned IP address;
and
otherwise, assigning the data packet an IP address in accordance with a different mode of network address translation

determining, from multiple modes of network address translation, a mode of network address translation for each outgoing data packets based upon the determined data packet type of each outgoing data packet;
and
performing network address translation on outgoing data packets based on the determined mode of network translation.
