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 system and method for improving communication between a switched network (133) and a packet network (136) is disclosed. In a simplified embodiment, a signaling gateway (152) is utilized for converting signaling in a first protocol into a second protocol, and from the second protocol to said first protocol. At least one media gateway (142,144) is utilized for converting multimedia provided in a first format into a second format, and from the second format into the first format. A session router (162) for selecting at least one multimedia transmission route to a destination (192) is also utilized, wherein the destination is specified by the switched network. In addition, a media router (164) is also utilized for guiding the multimedia to the destination (192) after conversion by the media gateway.

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.

- retaining in a local telephony routing information database (TRIB) all distinct routes described by received route information, each distinct route having the same degree of preference;
- if said route information is not discarded, comparing said received and screened route information to a local policy defined within said first session router; and,
- selecting a primary route from said received route information and local route information in accordance with said local policy, wherein said primary route is a path from said first session router to said second session router via said transport network.

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 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.
