ABSTRACT:
A communication network includes a network selection system and an enterprise system that are connected to a PSTN. The network selection system receives a connection request from the enterprise system through the PSTN network, identifies the enterprise system, retrieves a cost/performance profile of the enterprise system, retrieves ISP cost and performance information for each independent ISP of the plurality of independent ISPs, processes the ISP cost and performance information for each of the plurality of independent ISPs against the cost/performance profile, and selects the one independent ISP from among the plurality of independent ISPs based on the processing of the ISP cost and performance information against the cost/performance profile. Additionally, the network selection system receives updated ISP cost and performance information after the selection, re-processes the ISP cost and performance information against the cost/performance profile, and selects a new independent ISP based on the re-processing.
