Abstract
An asynchronous transfer mode (ATM) on-demand digital document delivery system and method are disclosed. The system includes a customer interface unit configured to permit a customer to order and receive a digital document on-demand. A server is provided which includes digital documents stored thereon for delivery to customers through a switched ATM network. A cache is coupled to the server for storing digital documents sent by the server when ordered by a customer. The cache reduces network traffic by satisfying the on-demand orders instead of the server.

15. A method for providing a digital document on-demand over an asynchronous transfer mode (ATM) network, comprising the steps of:
-
processing a customer request for a digital document received by a server through to a switched ATM network;
storing the digital document in a cache located within the ATM network;
