Method and system for preventing a timeout from reaching a network host
View Patent ↗A method and system for preventing a timeout from reaching a network host when bringing up a down link that is slow to waken. The method generally comprises receiving a request to access an information. If a link along a path to a remote computer containing the information is down, the link is established while concurrently returning a plurality of imposter responses, such as domain names, until the network link is established. Software implementing this method may be stored and executed in any network host. This method is particularly advantageous when waiting for a dial-up telephone connection to a network to be established.
1. A method of execution of computer readable instructions by a processor comprising:
receiving a first request to access an information on a remote computer identified by a domain name;

2. The method of claim 1 wherein sending one or more imposter domain names comprises:
sending an instruction that the domain name is an alias for a current imposter domain name of the one or more imposter domain names, wherein the current imposter domain name contains a text string attached to the domain name.

4. The method of claim 1 further comprising:
after the link is established, sending an instruction that an imposter domain name of the one or more imposter domain names is an alias for the domain name;
receiving a second request to access the information including the domain name; and
