A system for facilitating network performance analysis. In an illustrative embodiment, the system includes a first module capable of quantifying network performance associated with a first portion of the network and providing a signal in response thereto. A second module is capable of ascertaining performance degradations in a communications link traversing plural portions of the network that are attributable to the first portion based on the signal. In a more specific embodiment, the second module further includes a third module adapted to ascertain degradations in network performance associated with a second portion of the network based on the signal and based on a performance parameter associated with both the first portion and the second portion of the network. In this embodiment, the first portion includes a wireless portion, and the second portion includes a wired portion. The performance parameter incorporates a Frame Loss Vector (FLV) associated with a communications link that traverses the wireless and wired portions of the network.

A method is disclosed for providing fault tolerance of an application over a Stream Control Transmission Protocol (SCTP) connection. A method for moving a transport connection from a first host to a second host on a network is also described. After establishing a transport connection between the first host and a peer host, first information about the transport connection is transferred to the second host. Upon the first host becoming unavailable, the second host sends to the peer host a request to update the state of the transport connection. The peer host then updates the transport connection. Without resetting the transport connection, the second host then establishes the same transport connection with the peer host.

A method for handling media in a make-before-break handoff between wireless networks is provided that includes communicating with a mobile station to facilitate a session handoff between two call legs of a session. The method also includes identifying a relevant frame of one of the legs, performing a cross correlation operation, generating a delay difference estimate between the two legs, and performing a level difference estimation for the two legs.

A system and method are provided whereby periodic measurements of autonomic reflex times of individuals are used as an early-warning indication that an undesirable physical condition, such as an undesirable blood-chemistry condition, may exist. This method correlates measurements of the reaction times of specific autonomic reflexes to more-definitive measurements for the medical condition being monitored for this early-warning assessment.

Classifying signals includes receiving signals from communication devices, where each signal is received from a communication device. The following is repeated for each signal: a received signal from the communication device is encoded, whether the encoded signal is an undesirable auditory signal is determined, and the encoded signal is modified if the encoded signal comprises an undesirable auditory signal. The received signals are combined.

A system and technique for analyzing incoming packets. The path taken by incoming packets can be analyzed from a near end without having access to the far end. This can be done even though packets sent to the far end from the near end, take a different path than that used by the incoming packets. The process is started by an RTP no op packet sent from the near end to the far end. The no op packet request the far end to initiate a trace using a series of media packets that have sequential values in the TTL field. The results of the trace are either send from the far end to the near end and a report is complied at the near end, or the results of the trace are compiled into a report at the far end and the report is sent to the near end.

A mobile device supports concurrent registrations of different wireless personalities with one or more service provider networks. Potentially using a single wireless interface, the mobile device can register and maintain multiple personalities and monitor for notifications targeted to any one of these personalities.
