摘要： PROBLEM TO BE SOLVED: To enable high-speed packet switching at the time of failure, even in a broadband network. SOLUTION: A packet processing apparatus includes a plurality of IF units each connected with a counter apparatus via a work path or a protection path and an SW connecting the plurality of IF units via a data bus. When a packet sent from the counter apparatus is received by any one of the plurality of IF units, the packet processing apparatus determines whether the packet is a monitoring packet monitoring a connection state with the counter apparatus. When it is determined that the packet is a monitoring packet, the packet processing apparatus uses the data bus via the SW to transmit the monitoring packet to the plurality of IF units.

摘要： PROBLEM TO BE SOLVED: To provide a band control method capable of realizing high throughput and performing correctly band control, and to provide a packet processing device using the same. SOLUTION: An inputted variable length packet is enqueued into any one of a plurality of queues according to the class of the variable length packet. The packet length of the inputted variable length packet is divided by the segment length of fixed length to obtain the number of segments and a remainder for each packet. The number of segments for each queue being summation of the number of segments in a queue into which the packet is enqueued is obtained and maintained. Scheduling is performed per segment, and band calculation is performed with a segment length for a selected queue. The number of segments per packet and the number of segments per queue corresponding to the head packet of the selected queue are decremented by one. If the processing is a first processing of the head packet of the selected queue, the packet is dequeued per packet. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To relieve the load of the software processing by designating plural sets of sub rate information written in one time slot location of a talking memory with plural read time slots and differentiating readout bit location by a read address generating means. CONSTITUTION:An incoming time slot signal including a basic rate signal (A, B) and signals (a, b) of combined plural sub rates on one time slot is stored sequentially to a talking memory 2. Then a read time slot is designated by time slot information written by the software of a control memory 4 and the designation of bit location in each time slot is implemented by a read address generating means 5. That is, an address to designate a bit location is generated as to the position of the talking memory in which the sub rate is written by reading a first half 4-bit (information a) at a read time slot '2' twice commanded by the control memory 4 and reading a later half 4-bit (information b) at a time of the time slot '3' twice.

摘要： PROBLEM TO BE SOLVED: To improve throughput by reducing latency. SOLUTION: A memory 12 in a queue state stores queue state information as information related to packet storage of queues Q1-Qn to all the queues Q1-Qn. A prescheduler 13 reads out the queue state information regarding the selected queue from the memory 12 in a queue state by executing prescheduling, which is for previously selecting the queue highly likely to be required in actual scheduling, to the scheduling as processing for allowing stored packets to be outputted by selecting any one of the queues Q1-Qn. A cache memory 14 temporarily stores the queue state information read out with the prescheduler 13. A scheduler 15 executes the scheduling by utilizing the queue state information stored in the cache memory 14. COPYRIGHT: (C)2006,JPO&NCIPI
