Method of efficiently retrieving data on a computer network by monitoring performance of mirrored network locations

摘要

An improved method for efficiently retrieving data is associated with network locations within a computer network. First, a list of mirrored network locations is determined. Communication performance is then monitored during communication with the list of network locations. If the communication performance of a network location is below predetermined levels, an alternate network location from the list is accessed. The list of network locations is accessed in sequence to locate a network location having acceptable communication performance. During the sequential access of network locations data is cascaded to produce efficient retrieval of data utilizing computer networks.
