The method also comprises determining a digit string associated with the URI. The method also comprises sending a SIP informational response message having a contact header that contains information based on the digit string. | 2009-10-29 |
20090268727 | Early header CRC in data response packets with variable gap count - A method is provided for processing a command issued by a processor over a bus. The method includes ( | 2009-10-29 |
20090268728 | PROTOCOL INCOMPATIBILITY DETECTION - A network switch configured to detect protocol incompatibility and a corresponding method are described. The switch comprises one or more network ports and a memory. The memory stores a protocol set comprising one or more protocols each comprising protocol-specific identifying information and one or more actions to be taken by the network switch upon detection of the particular protocol. The memory also stores a protocol packet detection logic configured to perform at least one of the one or more actions responsive to detection of a corresponding protocol. | 2009-10-29 |
20090268729 | NETWORK DEVICE AND WORKING MODE SWITCHING METHOD - A network device includes a timing module, a traffic analysis module, a counting module, a mode switching module and at least one processor. The timing module sets a plurality of continual timing periods. Each of the continual timing periods includes a plurality of timing periods The traffic analysis module analyzes if the traffic transmitted by the network device in each of the timing periods in a continual timing period is less than a predetermined traffic threshold. The counting module counts an amount of the traffic transmitted through the network device is less than the predetermined traffic threshold in the continual timing period, and determines if the counted amount is less than a predetermined threshold. The mode switching module switches the working mode of the network device according to the determination of the counting module. The processor executes the timing module, the traffic analysis module, the counting module, and the mode switching module. | 2009-10-29 |
20090268730 | DATA TRANSMITTING APPARATUS AND METHOD AND PROGRAM FOR CONTROLLING TRANSMISSION RATE - A data transmitting apparatus includes a plurality of data transmitting sections each transmitting a stream through a network, an information acquiring section acquiring network traffic status information of each stream, a statistical process section performing a statistical process on the network traffic status information of each stream acquired by the information acquiring section, a calculating section obtaining an overall transmission rate based on the result of the process performed by the statistical process section, and a transmission rate setting section setting a transmission rate for each stream based on the overall transmission rate obtained by the calculating section and a preset allocation ratio. | 2009-10-29 |
