Abstract
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.
Claims36
A method comprising:
- receiving from a requester a request to access an information;
- if a link to a first remote computer containing the information is down, establishing the link while concurrently returning a plurality of imposter responses until the link is established.
A method comprising:
- receiving a domain name system (DNS) request initiated by an application program;
- if no Internet connection has been established, precluding a user from receiving an error message by establishing a dial-up connection to the Internet while concurrently returning a plurality of imposter domain names until the dial-up Internet connection is established.
A network host comprising a processor and a machine readable medium containing instructions which when executed by the processor cause the processor to perform operations comprising:
- receiving from a requester a request to access an information;
- if a link to a first remote computer containing the information is down, establishing the link while concurrently returning a plurality of imposter responses until the link is established.
