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： Mobility in a wireless ATM network is accomplished by use of hand-off control protocols. A mobile terminal signals a first base station that a hand-off is to occur. In a first preferred embodiment the first base station signals a second base station requesting a hand-off. After the second base station signals the first base station that a datapath link is available from a hand-off switch to the second base station, the hand-off switch causes the datapath to change from the first base station to the second base station and the first base station signals the mobile terminal to commence communication with the second base station. In a second preferred embodiment, the mobile terminal signals a first base station that a hand-off is to occur. The first base station signals a second base station requesting a hand-off. At the same time a datapath link is established between the first and second base stations. When the second base station signals the first base station that the datapath link is available, the first base station signals the mobile terminal to change to the second base station and data is sent from the first base station to the second base station via the available established datapath link.

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.
