    摘要： A system and method for providing rapid rerouting of real-time transport protocol (RTP) multi-media flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor configured by the software. The processor is configured to perform the steps of, performing flow processing on a data packet received at a first endpoint, from a second endpoint, removing a multi-protocol label switching (MPLS) tag from the data packet, translating a source address and destination address of the data packet, and determining a forwarding destination if more than one destination address of the data packet is provided.

    摘要： A system for providing encryption for the rerouting of multi-media data flow packets is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, encryption software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor. The processor is configured by the encryption software to perform the steps of: assigning a sequence number to a first multi-media data flow packet received by a first endpoint, wherein the first multi-media data flow packet is within a series of multi-media data flow packets; pseudo-randomly shuffling the sequence number of the first multi-media data flow packet; and, transmitting the pseudo-randomly shuffled sequence number to a second endpoint. These steps may be performed by a programmed controller, or other hardware, instead of, or in addition to, being performed in accordance with software.

    摘要： A system and method for determining flow quality statistics for real-time transport protocol (RTP) data flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor. The processor is configured by the software to perform the steps of, determining latency for the RTP data flows, determining jitter for the RTP data flows, and/or determining lost packets for the RTP data flows. Latency is determined by the first endpoint transmitting a test data packet to the second endpoint; the second endpoint looping the test data packet back to the first endpoint; comparing when the test data packet was received by the first endpoint to when the test data packet was sent to the second endpoint, to determine a round trip time; and, dividing the round trip time in two, resulting in the latency. Jitter is determined by beginning a timer when a first data packet of an RTP data flow is received by the first endpoint; stopping the timer when a second data packet of the RTP data flow is received by the first endpoint; and, adding measured time from the beginning of the timer to the stopping of the timer to an aggregate to obtain the jitter for the RTP data flow. Lost packets are determined by determining a sequence number of a received RTP data packet within the RTP data flow; storing the determined sequence number; calculating whether the determined sequence number sequentially falls within a numerical order; and, if the sequence number of the received RTP data packet does not sequentially fall within the numerical order, storing the sequence number as a missed RTP data packet.

    摘要： A dynamic transaction network having multiple management stations, one or more terminals, and one or more databases is disclosed. The dynamic transaction network is capable of adding and removing network hosts (terminals, databases, and management stations) in real-time while continuing to service transaction requests. In addition, the dynamic transaction network is capable of transferring database fragments from a source database to a target database in real-time. In response to a transaction request from a caller, the terminal accesses information stored in a corresponding database via dynamic transportable logic. The dynamic transportable logic derives the location of relevant information in the database from input characteristic(s) of the transaction request. The transportable logic stored in the one or more terminals may be updated with transportable logic stored in the management station if a host determines that there is a difference between its transportable logic and the management station's transportable logic. A method for initializing a distributed, scalable, dynamic transaction network is disclosed as well. The method comprises: identifying each host; verifying each host has a current copy of the network configuration; updating the network configuration as required; and periodically repeating the process.
