ABSTRACT:
A stream manager provides a way of redirecting and managing messaging and information access in a packet network environment. The stream manager can include a computer-based router or server that behaves as if it were a gateway for a sub-network of destination site servers, and the stream manager is linked to a packet network, such as the Internet. The stream manager receives over the packet network a message from a user's host server initiated by a user and intended for a destination site. The message bears an address for the stream manager which is provided to the host server by the address server for the packet network, such as a server utilized as part of the domain name system. The stream manager determines the availability of at least one destination server at the destination site to receive and process the message. If a destination server at the destination site is available to receive and process the message, the stream manager selects a destination server from those available, and initiates the routing of the message to the selected destination server. If a destination site is unavailable, the stream manager may report that to the host server, along with other information (such as customer care or promotional information).
