摘要： The present invention provides a technology for processing packets, such as VoIP packets, with priority. A priority-designating unit designates priority information based on header information. A pointer searching unit refers to a pointer table to obtain pointer information corresponding to a destination address. A sorting unit sorts the pointer information into a high-priority queue and a low-priority queue according to the priority information. A next queue holds pointer information obtained from a destination information table. A scheduler extracts and outputs the pointer information from each queue in the following order of priority: the next queue, a high-priority queue, and a low-priority queue. A destination-information-table searching unit obtains destination information and/or the pointer information from the destination information table based on the pointer information, and outputs the destination information to a packet forwarding and duplicating unit and outputs the pointer information to the next queue.

摘要： A traffic shaping apparatus calculates a minimum transmission interval, an allowed transmission frame rate of a user frame, and a reference transmission interval for each user according to a minimum transmission frame rate and a peak transmission frame rate specified for each user. The traffic shaping apparatus also calculates a first estimated transmission time according to the reference transmission interval, and a second estimated transmission time according to the minimum transmission interval for each user. The traffic shaping apparatus determines the user having the earliest first estimated transmission time, and determines according to the second estimated transmission time of the user whether a user frame is to be transmitted.
