摘要： One or more network elements that modify type of service values in a network are detected by sending route tracing messages having increasing time-to-live values and a designated type of service value from a first network element to a second network element. Type of service values are monitored in respective time exceeded messages received from respective network elements on a given network path between the first network element and the second network element responsive to the route tracing messages. At least a particular one of the network elements on the given network path that has made a modification in type of service value relative to the designated type of service value is identified, based on the monitored type of service values in the respective time exceeded messages.

摘要： A method that seeks to provide a satisfactory quality of service for a stream of packets through a network. The illustrative embodiment of the present invention seeks to provide a satisfactory quality of service for a stream of packets by periodically or sporadically evaluating one or more alternative paths through the network and by sending the packets through a path with an acceptable quality of service. Normally, neither the source node nor any other node in a packet's path controls its route after it has left the node. In contrast, the illustrative embodiment of the present invention has the capability to affect the packet's path through the network by sending the packet to an intermediate or “ricochet” node in the network, which forwards the packet to the destination node. In effect, the source node can, if it deems appropriate, ricochet the packet off of the intermediate node rather than allowing the packet to take its normal direct path through the network.

摘要： A network analyzer gets configuration information, usually in the form of a configuration packet sent from a network monitor. The configuration information comprises a second device network address and a third device network address. The second device network address is that of the network monitor and the third device network address is that of a communication device that is to be monitored.When the network analyzer sees packets from the monitored communication device, it can send the results to the network monitor for analysis without having to be configured with a unique network address. The network analyzer sends an original packet using the network address of the communication device as the source address and using the network address of the network monitor as the destination address.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating an end-to-end quality indication associated with a communication session. Based on a real-time transport control protocol message, the system identifies a media path associated with a communication session. Next, the system determines a respective media leg quality for a plurality of media legs in the media path. Based on the respective media leg quality, the system then determines a media path quality. The system can also generate a media quality indication based on the media path quality, and display the media quality indication.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for managing a packet network to deal with a problem of dropped audio packets. A triggering event signal indicates that audio marked packet traffic in the packet network has exceeded a capacity limit. Upon receiving the triggering event signal, a transmitting device transmits audio packets marked as non-audio packets through the packet network. The transmitting device, for example, is a VoIP telephone. The triggering event signal, for example, is generated when the audio marked packet traffic exceeds a dropped packet threshold, or when monitoring of audio marked packet traffic indicates that audio marked packet traffic approaches a committed data rate (CDR) threshold.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for analyzing packet flows and generating an alarm and for active testing of a network to localize problems. The system analyzes packet flows for bitstreams associated with a network node in order to compute a measure of protection that a queue of the network node gives to a high-priority one of the bitstreams relative to a low-priority one of the bitstreams, and uses the measure of protection to determine whether the network node is a source of a protection error with respect to priority markings for packets flowing through the network node, and generates an alarm upon determining that the network node is a source of a protection error with respect to the priority markings for the packets flowing through the network node.

摘要： A network monitor gets a bill of materials for a communication across a network where different communication paths may be established. A bill of materials is a list of hardware/software components that are used to establish and maintain the communication. A request to generate a test communication between the same devices involved in the communication is received. A request to sample and send samples of test data is sent to a network analyzer. The test communication is established. A bill of materials for the test communication is determined. The bill of materials for the communication is compared to the bill of materials for the test communication. Test data is sent on the test communication. The sent test data is analyzed in relation to the sent samples of the test data and the compared bills of materials.

摘要： An apparatus and method are disclosed that enable a first telecommunications endpoint to ensure that a second endpoint is receiving the first endpoint's packet stream transmissions with a satisfactory waveform quality. When the second endpoint receives the packet stream, it decodes the media waveform from the stream, encodes the waveform back into a second packet stream, and transmits some or all of the packets in the second stream back to the first endpoint. The first endpoint then decodes the received waveform in the second stream and compares it to the original waveform transmitted to the second endpoint. Based on the comparison, the first endpoint adjusts the value of a quality indication, and provides the quality indication to its user and to the second endpoint. Advantageously, the user at the second endpoint is able to determine whether the received waveform is, in fact, close enough to the waveform that the first endpoint's user intended to be received and understood.

摘要： A technique is discloses that enables a first telecommunications terminal, wireless or otherwise, to report to its user whether a second, wireless telecommunications terminal is receiving the first terminal's packet stream transmissions at a satisfactory quality level. The second terminal receives the packet stream that conveys the media waveform transmitted by the first terminal. The media waveform can be that of the speech signal of the first terminal's user. The second terminal measures a trait of the received signal and encodes the measurement data into the packet stream that the second terminal is already transmitting to the first terminal. The first terminal then decodes the measurement data from the received second stream and presents, to its user, a quality indication that is based on the measurement data. In doing so, the first terminal provides its user with a better idea of whether the second terminal has reliably received the user's communication.
