摘要： An apparatus and method for switching VOIP packets in a data network, wherein the method includes the steps of receiving a first packet in a network switch and determining if the first packet is a VOIP packet. Further, method includes determining a dynamically negotiated VOIP port for a VOIP session from at least one of the first packet and a second packet received in the network switch, if the first packet is determined to be the VOIP packet. Finally, the method includes the steps of classifying all subsequent VOIP packets corresponding to the dynamically negotiated VOIP port in accordance with predetermined parameters. The apparatus includes a network switch having at least one data port interface controller supporting a plurality of data ports for transmitting and receiving data, and a fast filtering processor in communication with the at least one data port interface. At least one filtering table in communication with the fast filtering processor is provided, wherein the fast filtering processor is configured to snoop packets being transmitted through the network switch to trap a VOIP call setup message, and thereafter, determine a dynamically negotiated VOIP port so that all subsequent VOIP packets can be filtered and assigned an appropriate priority.

摘要： The invention provides a communications session switching method and system that switches a session established between communications terminals while maintaining an application in session. A first communications terminal (1) includes a step of detecting a session switching factor and extracting configuration information on a switching target session and a step of transmitting a message including the session configuration information and session switching factor to a session management server. A session management server (4) includes a step of transmitting the message to a communications terminal in a switching target session. First and second communications terminals include a step of changing gateways and an application setting based on session configuration information and a session switching factor registered in a received message and a means of transmitting a session switching completion message to the session management server after completion of the setting change.

摘要： A data switch (4) is proposed which can be operated such that it generates a MA table of MAC addresses of devices associated with some of its ports (9, 13, 15, 17, 19), but not the MAC addresses associated with one of the ports (11). Packets received by the switch, other than from the port (11), are assumed to be destined for the port (11) and are transmitted via the port (11). If the port (11) is connected to a network, and all the other ports are connected to a relatively small number of devices, such as one device per port, then the memory requirement to store the MA table is dramatically reduced.

摘要： The invention is a system for providing virtual connections through an ATM interworking multiplexer on a call-by-call basis. A signaling processor receives signaling for a call and selects the virtual connection for the call. The signaling processor generates new signaling that identifies the selection and transfers the new signaling to the ATM interworking multiplexer that accepted the access connection for the call. The multiplexer converts user information from the access connection into ATM cells for transmission over the virtual connection in accord with the new signaling.

摘要： The present invention is directed to a high speed packet switching network and, in particular to a method and system for minimizing the time to establish a connection between an origin and a destination node. A path calculated at the time the connection is requested is recorded in a Routing Database and updated each time a modification occurs in the network. Furthermore, alternate paths for supporting non-disruptive path switch on failure or preemption, and new paths towards potential destination nodes can be calculated and stored when the connection set up process is idle. These last operations are executed in background with a low processing priority and in absence of connection request.

摘要： A method and apparatus for communication system buffer size and error correction coding selection. A method includes the steps of receiving a stream of data packets by a real time receiver that includes a buffer management device, a first plurality of jitter buffers, and a second plurality jitter buffers. The first and second plurality of jitter buffers are evaluated and a first and a second optimal jitter buffer is chosen. The first and the second optimal jitter buffer has an associated conditional optimal performance characteristic. The conditional characteristics are compared and a preferred buffer of the receiver is selected. The apparatus includes a receiving device including a first set of jitter buffers and a second set of jitter buffers with error coding. The first set includes a plurality of buffers and a second plurality of buffers maintained in the second set of buffers. The apparatus also includes a means for comparing the first plurality of buffers and the second plurality of buffers, a means for selecting a first optimal buffer from the first plurality of buffers, and a means for selecting a second optimal buffer from the second plurality of buffers. Either the first or the second selected optimal decoder determines the receiver buffer size and whether forward error correction is utilized.
