摘要： The present invention relates to a buffer control apparatus and method. In a buffer control apparatus for controlling storage process for a common buffer which is commonly used for a plurality of routes and temporarily stores data received from the routes, the buffer control apparatus comprises a route discriminating section for identifying the routes of the received data; a storage section for storing at least information concerning a storing position for the received data within the common buffer for each of the routes; and a control section for performing a control operation for virtually storing, route by route, the received data into the common buffer according to a result of route identification in the route discriminating section and the information concerning the storing position in the storage section, whereby the storage control in the common buffer is performed such that the common buffer can be virtually used as discrete buffers, in order to secure minimum band for each of the routes without increasing the capacity of the buffer and complicating the readout control for the buffer.

摘要： A packet transmitting apparatus according to the present invention includes a plurality of ports. When the same unlearned packets have arrived at the plurality of ports, the packet transmitting apparatus judges through packet processing section that the first arrived one of the packets is a previous arrival packet. Then, through previous arrival group judging section, the packet transmitting apparatus selects from the plurality of ports a plurality of ports satisfying a previous arrival port condition for determining a port at which the previous arrival packet arrives as a previous arrival port. The packet transmitting apparatus judges the thus selected plurality of ports as the previous arrival ports having an equal previous arrival characteristic of packets, and includes the ports in a previous arrival port group.

摘要： A learning-target packet to be used for a path learning is selected from among a plurality of packets queued by a relay apparatus. A relationship between a transmission-source address and a first-arrival port for the selected learning-target packet is registered as learning information. A packet corresponding to the registered learning information is transferred to the first-arrival port pertaining to the learning information, and a packet that does not correspond to the learning information is transferred to all ports to which the packet is to be transferred.

摘要： When a packet arrives, a packet processing unit judges whether coincident information is present in an identity information table. When no coincident information is present, the packet processing unit registers the entire packet, a hash value of the entire packet, a predetermined part of the packet, or a hash value of the predetermined part of the packet. In addition, the packet processing unit performs identity judgment for the packet based on the information registered in the identity information table.
