Abstract

A dynamic network configuration in a computer records and analyzes network transactions to permit dynamic configuration of network parameters when connecting the computer to a network. Upon initial connection of the computer to the network, user preferences and network parameters for other locations previously encountered are read or entered into memory of the computer. The dynamic network configuration gathers network traffic data by entering a learn or promiscuous mode to record a number of network transactions for a predetermined time period. The network traffic data is indexed for analysis to determine the participants. The current participants are compared with the existing participants for previously observed locations. If a match occurs, then the network parameters are utilized to configure a protocol stack.
