    摘要： The present invention is directed to a system, including apparatus and architecture, and method for providing scheduled and ad hoc voice over IP conference services having enhanced quality and reliability. The system uses an overlay network of geographically distributed conference servers working simultaneously and collaboratively to host a given conference session. Multiple conference servers simultaneously and collaboratively perform the necessary audio mixing. The voice routing path is established and controlled within the overlay network and supports conference services across different conference service providers.

    摘要： A method and system for reliable multicasting on a communication network includes sending Request-to-Send (RTS) signals from a sender node of the network to the receiver nodes, the RTS signals include a set of identifiers corresponding to the receiver nodes. The Clear-to-Send (CTS) signals and Acknowledgment (ACK) signals are sent from the receiver nodes according to an ordering function of the set of identifiers.

    摘要： This invention provides methods and apparatus for validating that transformations that are expected to occur in an IP network are indeed occurring as expected. Generally, these transformations establish logical communication tunnels within an IP network between the devices that perform the transformation and the devices that perform the reverse transformation. The invention is useful to validate the configuration of devices that support a variety of IP transformation methods, including IP-security protocols using the standard Encrypted Secure Payload protocol and Authenticated Header protocols as defined by the IETF. The invention is particularly useful to validate cases in which transformations occur on the full path of a packet traversing between two machines in an IP network, or when the transformations only occur on part of this path.

    摘要： A method, an apparatus and an article of manufacture for managing a subscription hierarchy in a presence system. The method includes receiving a presence information request within a presence server, wherein the request is one of a subscription request and an un-subscribe request, determining if the request corresponds to an existing subscriber in the presence server, and if so, sending a redirect message to the existing subscriber, and if not, processing the request within the presence server, and enhancing functionality of subscribers to accept and handle subscription and un-subscribe requests.

    摘要： Systems and methods are provided for the close coupling of Session Initiation Protocol (SIP) based Voice over Internet Protocol (VoIP) with multiplayer network games. Game state dependent voice communications are used as another method of player interaction in the game environment. The system uses SIP enhanced game servers and conference servers with audio mixing capabilities, and the game server controls the creation, maintenance and changing of the voice conferences. Participation in a voice conference is determined by the game state features associated with each player including distance and direction to determine how the voices are mixed in a voice conference.

    摘要： Systems and methods are disclosed for differentiated handling of VoIP call control messages according to their importance and functionality, thus providing to VoIP infrastructures a level of robust call control similar to that in PSTN networks. SIP messages are classified by their type or content, and resources of a VoIP call control server are allocated to the SIP messages according to a policy. The scheme also provides overload protection and prioritized handling of certain kinds of requests in VoIP call control servers.
