Abstract: One aspect of the specification is the use of a virtual entity to represent the bandwidth bottleneck point in a network. Areas of the network where bandwidth does not need to be managed can be modeled as zones. This model enables more flexibility as the virtual bottleneck point can represent a collection of components (e.g. routers), or a portion of a real component (e.g. a router could be represented by multiple virtual bottleneck points with different purposes.) This model can also allow a user to decide which points in their network should be managed, independent of the underlying data network infrastructure. These virtual entities can be placed between areas of the network, and configured with specific policies. Bandwidth usage across these virtual entities can be tracked and compared to the configured bandwidth limit available to the application at each bottleneck point. When the bandwidth available at the bottleneck point is fully utilized, additional calls can be blocked or rerouted.

Abstract: A system and method of providing an assignable registration between a device and a user for IP telephony, wireless telephony and other forms of collaborative systems is provided wherein loss of association is detected and a policy language is used to capture and execute user preferences in the event of such loss. A method and system are also provided for utilizing coupling between a thin client and a telephone to provide for device association.

Abstract: This specification can provide resource allocation in peer-to-peer networks. This specification describes techniques whereby individual resources can in certain circumstances share their local views to create a network-wide view. The use of a performance manager facilitates this sharing. The sharing of fault information both access multiple devices and for a single device across restarts is also provided. A network-based aggregator for performance and fault analysis is also provided so that complex analysis algorithms can be provided centrally to assist network performance management.

Abstract: A system and method of associating at least two communication devices is provided. First information identifying a first communication device and second information identifying a second communication device is received via a link layer protocol over a data network. It is determined if the first communication device and the second communication device are co-located based on first link layer data associated with the first communication device and second link layer data associated with the second communication device. An association is triggered between the first information and the second information if the first communication device and the second communication device are determined to be co-located.

Abstract: A system and method for enhanced operation of internet protocol (IP) telephony is disclosed. The system comprises a call server. The call server includes a shared resources module, a virtual machine environment in communication with the shared resources module the virtual machine having a plurality of virtual machines. A plurality of telecommunication function applications operate on separate instances. Each instance is operable to be connected to a customer through a network connection in communication with at least one of the plurality of virtual machines.

Abstract: A system for remote assembly of messages to create a control message includes a shared coordination space for assembly of messages, and a plurality of components for performing predefined actions and for exchanging messages according to a predetermined ontology. The plurality of components includes a first component for directing other ones of the components to publish information on the coordination space and in response gather several distinct pieces of the information and assemble the distinct pieces as a message by which to control the actions of the component. According to a preferred embodiment, the shared coordination space is a tuple space, one of the components is a call control application for controlling a communication switch, and at least one other component is a directory application containing location information.

Abstract: A network implemented communication system, comprising a Local Area Network (LAN), a plurality of endpoints connected to the LAN, each of the endpoints including a communication application for communicating via a standard protocol, at least one server connected to the LAN for third party control of communications between the endpoints, and software within each of the endpoints and the server for implementing features which do not require direct connection between the endpoints.

Abstract: A system and method for providing early detection of encrypted signals within a secure connection for voice over Internet protocol (VoIP). The system and method includes a non-complex, in-band, and early encryption detector within the voice path. A transmitter sends out a known pattern. Based upon the received pattern, the receiver decides whether its encryption capabilities match up with those of the transmitter. If the capabilities do not match, then the receiver waits for the signalling message for the correct mode of operation. No packets are utilized until the receiver and transmitter encryption capabilities are matched.
