    摘要: A control mechanism enables a destination router to authenticate a response time request issued by a source router. The control mechanism uses a control message that is transmitted by the source router to the destination router. Receipt of the control message by the destination router causes the destination router to listen for a server request message for a designated response time. The source router, after sending the control message, transmits a server request message to the destination router. In the event that the destination router receives the server request message within the designated response time, then the destination router responds to the server request message by providing the request to service software. The control message may encapsulate a message that holds the response time request. The request message may be encrypted.

    摘要: Internet protocol (IP) performance monitoring method and apparatus generate a timing probe data to be sent over the network, the timing probe data packet containing at least a send time of day (STOD) stamp for a sender of the timing probe data packet. The timing probe data packet is sent over the network from the sender to a receiver. The timing probe data packet contents including at least the STOD stamp are analyzed as a performance measure of the network. After sending and before analyzing, data including at least a receive time of day (RTOD) stamp is written into the probe data packet at the receiver, and probe data packet is echoed by the receiver. In this way, the probe packet sender performs the analysis based upon the STOD stamp and the RTOD stamp.

    摘要: A device for measuring network performance in an Internet protocol (IP) network including a counter generating a send sequence number representing a relative send timing indicator for a data packet sent to a respondent network address. The counter generates a receive sequence number representing a relative receive timing indicator for a return data packet received by the device. A comparator compares the send sequence number with the receive sequence number to measure data packet loss.

    摘要: An apparatus for measuring data transmission performance through a packet switched network, the apparatus having a time of day (TOD) clock for determining a send TOD timestamp, and for determining a present TOD when a data packet returns to the sending apparatus. The apparatus further comprising a counter that is incremented by a send sequence number each time data is sent, and one or more subtractors for calculating a first time difference between the send TOD timestamp and a receive TOD timestamp, and for calculating a second time difference between the receive TOD and the present TOD. Additionally, one or more comparators of the apparatus compare a sequence difference between the send sequence number and a receive sequence number in order to measure data transmission performance.

    摘要: An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and operable to receive a plurality of packets associated with a communications flow, the packets including a plurality of subrates. The cell site element is further operable to detect a congestion condition via a measurement of a level in a receive jitter buffer. When the congestion condition exists, individual subrates can be dropped from subsequent backhaul packets until congestion subsides. In more particular embodiments, the cell site element can be informed that congestion exists, whereby a congestion level is assigned to a collection of the subrates. In addition, the cell site element prioritizes the subrates and removes individual samples from one or more of the packets; high priority calls and critical radio control information are not affected during the congestion condition.

    摘要: A signaling network node is configured for identifying a received signaling message as belonging to one of a plurality of prescribed originating node groups, based on prescribed message class selection criteria. Each originating node group has at least one originating node and is assigned at least one congestion threshold relative to a message rate (e.g., messages per unit time or number of bytes per unit time). The signaling network node determines the message rate for each corresponding originating node group; if the message rate for an originating node group exceeds the corresponding at least one congestion threshold, the signaling network node outputs a congestion signaling message to the originating node having sent the signaling message, for reduction of the corresponding message rate.
