Abstract

In an arrangement where users are connected to an ISP through a bank of modems, a time-out threshold is then selected for the user based on the user's connection pattern. The threshold is varied dynamically in response to access patterns, in an attempt to trade the benefit accrued by using the ISP's modem and phone line for a shorter period of time, against the inconvenience to the user from having to reestablish a connection to the ISP. Specifically, the time interval between the last disconnection by the user and the time of reconnection is evaluated, and when this time interval is shorter than a preselected threshold, then the time-out threshold is increased. When this time interval is longer than the preselected threshold, then the time-out threshold is decreased. Typically, when the time-out threshold is decreased, it is decreased by a significantly smaller amount that the amount by which it is increased, when it is increased.
