This disclosure relates to a specific, illustrative multilayer architecture for a program controlled
system for providing services relating to financial data computation, report remittance and funds transfer services over an interactive communications network. The
system comprises a subscriber
server for hosting a virtual portal having at least one application for providing e-content to end users, the application including a network browser for accessing, displaying and transmitting data over the network. A first
service provider server allows a
system administrator to access the system remotely. A first
security system for protecting the system from entry of unwanted data during data transfer over the network between the subscriber and
service provider servers and the interactive communications
network level. Also provided are plurality of primary servers including a primary network
server, a primary tax computation server, a primary
report generation server and a primary tax remittance server. The network server receives a tax computation transaction request from the subscriber server, transmits the request to the primary tax computation server, and returns data processed by the tax computation server to the subscriber server. In addition, the system has a plurality of secondary servers redundant to the first. The secondary servers include a secondary network server, a secondary tax computation server, a secondary
report generation server and a secondary tax remittance server. A load balancing and
scalability system is utilized for load directing, routing and switching functions during data transfer from utilization of at least one function at one of the primary servers to a corresponding function at a secondary server for optimum management of system resources.
