摘要： PROBLEM TO BE SOLVED: To reduces packet discarding in an equilibrium state.SOLUTION: A band control apparatus includes a buffer memory, a counter management section, and a control section. The buffer memory is configured to hold and output data units on a first-in first-out basis. The counter management section is configured to hold a counter value, to add a value to the counter value on the basis of a predetermined rule and, when outputting a data unit from the buffer memory, to reduce a size of the first data unit from the counter value. In the case where a first condition is satisfied that a total size of the data units held in the buffer memory is smaller than a predetermined buffer threshold, and in the case where a second condition is satisfied that the counter value is larger than the size of the first data unit, the control section is configured to output the first data unit in the buffer memory and in the case where the first condition is not satisfied, the control section is configured to cause the data units to be outputted sequentially from the first data unit, until a predetermined third condition is satisfied.

摘要： PROBLEM TO BE SOLVED: To easily attain the band limiting of each service class without affecting scalability. SOLUTION: A policer presets a threshold for determining whether or not to abandon an arrival packet by being compared with a token residual amount when the packet arrives to a token consumed accompanying the passing of the arrival packet for each band using ratio (for each ratio rank ranked by the band using ratio). The policer abandons the arrival packet when the token residual amount when the packet arrives is less than the threshold set to the token for the band using ratio (ratio rank) of a class (network flow) to which the arrival packet belongs.

摘要： PROBLEM TO BE SOLVED: To provide a apparatus for switching packet suppressing particular packets, on the basis of a storage capacity for the particular packets (such as simulcast packets) so as to prevent increase in the particular packets affecting general communications (the occurrence of the so-called "broadcaststorm" or the like). SOLUTION: The packet switching apparatus for receiving packets and transferring them includes a counter for indicating the storage capacity of the particular packets in stored packets; and a means for starting transfer limit of the particular packets, when the count of the counter exceeds a preset transfer limit start threshold. The transfer limit is e.g., a processing of lowering the priority of the particular packets among the received packets. The packet-switching apparatus is furthermore provided with a means for releasing the transfer limit, when the count of the counter becomes smaller than the transfer limit end threshold set in advance.

摘要： PROBLEM TO BE SOLVED: To determine discarding of an arrival buffer using an index different from a queue length of a packet buffer. SOLUTION: When a new packet arrives, a packet buffer management apparatus obtains a residence time, in a packet buffer, of at least one packet stored in the packet buffer for temporarily storing packets. In a case where the residence time satisfies a discarding condition of the new packet, the new packet is discarded. In a case where the residence time does not satisfy the discarding condition, it is determined to store the new packet in the packet buffer. In a state where a time of arrival is added to the new packet determined to be stored, the new packet is stored in the packet buffer. COPYRIGHT: (C)2010,JPO&INPIT
