Abstract: A method of establishing Quality-of-Service (QoS) communications within a network proposes the encapsulation of a control message that facilitates QoS for an associated data flow, according to a protocol not implementing resource reservation, such as the User Datagram Protocol (UDP). The encapsulated control message is then propagated through the network on a routed path, while the associated data flow is propagated over a short-cut path through the network.

Abstract: A method which can be implemented on a computer program product for use on a network of autonomous systems to provide an ability to exclude the routing of messages to a destination IP address through a specified autonomous system. On a network in which each autonomous system ignores update messages that already include its identification number and adds it own identification number to update messages that it forwards, the method involves adding the identification number of the specified autonomous system to any update message created for the destination IP address.

Abstract: A system for automatically handling incoming telephone calls. The system receives an incoming call and telephony information about the incoming call, and, using a call discrimination subsystem and based on the telephony information, assigns control of the call to one of a plurality of possible application programs. At least one application program includes queries for obtaining further information about the call and returns control of the call to the call discrimination subsystem to reassign the call based on the telephony information and the further information. The system selects an application program by comparing telephony information about the call with telephony digit patterns that correspond to different types of telephony information and that have been input by a user to be associated with an application program.

Abstract: An NpR variable bandwidth control system comprises a class of systems specifically designed to control the access to a T1 link by traffic types that require different fractions of the transmission facilities simultaneoulsy. These systems can be incorporated into the software that is used to control DSC based T1 networks for special services. Essentially, wideband messages such as video signals are transmitted one at a time, whereas low bit rate data signals such as voice are transmitted in parallel. Such a form of transmission makes economical sense in the transmitting of such signals. A proportion p is applied to one of the group so that all data is equitably handled.
