ABSTRACT:
A communications network has a plurality of users connected by virtual circuits to a plurality of service providers. A server has the plurality of users connected thereto. A node provides the plurality of service providers. Both the server and the node are connected to the network. A first session is established between one user and the server, and a second session is established between the node and a selected one of the service providers. A virtual circuit is established linking the first service session and the second service session to establish message transmission between the one user and the selected service provider. A message sent between the user and the service provider is sent over the network, and the message identifies the virtual circuit. Messages between a server and a node are multiplexed by having slots, and a slot contains a message from a sending session to a receiving session.
