A method and apparatus determine a trust level of a path through a plurality of routers by an endpoint by transmitting a path setup message requesting a path reservation for a first path through a subset of the routers, by receiving in response to transmission of the path setup message a trust level message containing trust level information inserted by each router in the first path through the subset, and by evaluating the inserted trust level information to determine if the first path has a sufficient trust level. Another method and apparatus gather trust level information from a router by receiving a trust level message into which a trust level of the router can be inserted, by inserting trust level information of the router into the trust level message, and by re-transmitting the trust level message on a designated path.

Method and apparatus for trust based routing in data networks

Utilizing individual voice recognition units for each speaker in a conference to perform automatic transcription of that speaker's contribution to the conference. The output of each of the voice recognition units is then merged on a time basis to produce a textual transcription of the entire telecommunication conference call.

Apparatus and method for providing voice recognition for multiple speakers

The present invention is directed to a system and method for determining one or more credentials of a network device. The system and method select a first network device from among a plurality of network devices, access a credential repository, contact the first network device, and test the validity of the first set of credentials. The credential repository comprises a first set of credentials corresponding to the first network device. If a user provides invalid or no credentials, a candidate credential queue can be used to guess a valid second set of credentials when the first set of credentials is not valid.

Credential management and network querying

The present invention is directed to the measurement of service levels provided by a communication network, including an Internet protocol communication network. In accordance with the present invention, test packets are sent from a first edge router across the communication network to a second edge router. The time required for the test packets to be transmitted across the communication network is then determined, and that time compared to the time specified by the governing service level agreement. A failure of the communication network to deliver test packets as guaranteed may be used as an indication that the service level agreement has been violated. Packet loss and packet jitter may also be measured and compared to levels guaranteed by the service level agreement. The present invention may be used to determine whether the delivery of data packets using requests for expedited service levels is necessary or desirable.

Method and apparatus for auditing service level agreements by test packet insertion

A system for determining a topology associated with a network such as an enterprise network. The system includes a data collection agentconfigured to (a) identify a first set of routers from among a larger, second set of routers in an enterprise network, (b) contact each of the routers in the first set of routers but not each of the other routers in the second set of routers, and (c) load network information maintained by at least some of the contacted routers in the first set of routers. The loaded network information can then be used to form a network or routing topology of the enterprise network.

Using link state information to discover IP network topology

Producing a textual transcription of a communication conference call. A participant who is going to be absent from the conference can indicate to a conference bridge key words defining topics of interest, and the conference bridge will identify these topics based on the textual transcript that is being done in real time. When the participant returns to the conference call, they can then search the portion of an audio recording that they missed utilizing index marks defining the topics of interest that are based on the entered key words.

Apparatus and method for providing advanced communication conferencing operations

A system for discovering a topology of a distributed processing network that includes a first topology discovery agentconfigured to contact a first set of routers to obtain a first type of information stored in each router in the first set of routers; a second topology discovery agentand/orconfigured to contact a second set of routers to obtain a second type of information stored in each router in the second set of routers, and a phase controllerconfigured to select between the first and second topology discovery agents. The first and second sets of routers are different, and the first and second types of information are different. In one configuration, the first type of information is defined by a network management protocol, and the second type of information is defined by a routing protocol.
