摘要： A high quality network is provided by not generating a sorting time when registering look-up conditions in a content addressable memory, and the physical banks activated during look-up of the look-up conditions are limited. The power consumption in a content addressable memory for routing and content addressable memory for flow control can be reduced by a hash function unit for routing for limiting the physical banks to be made active in a content addressable memory for routing which uses a routing look-up key or routing look-up data as input elements, and a routing register which stores values showing one or more physical bank numbers for converting hash values which may have discrepancies, and a hash function unit for flow control for limiting the physical banks to be made active in a content addressable memory for flow control which uses a flow control look-up key or flow control look-up data as input elements, and a flow control register which stores values showing one or more physical bank numbers for converting hash values which may have discrepancies.

摘要： A high quality network is provided that eliminates the sorting time for sorting through registering look-up conditions, such as source and destination MAC addresses, in a content addressable memory, by generating a routing or flow control look-up key, and then selectively activating some of the physical banks in the content addressable memory with the look-up key during look-up for the look-up conditions. The look-up key is generated by extracting a part or all of the data contained in a packet header.

摘要： Between network node apparatuses that operate as a duplex system, when a failure occurs in an information processing unit of one system, the service is maintained and continued in an information processing unit of the other system without interruption of the service. In a system using an active system network node apparatus 100-1 and a standby system network node apparatus 100-2 both in an operating state, a switch processing unit 110 has a transfer processing unit 112 that copies and transfers a packet flow to be a subject of information processing in the information processing unit 200 to two output destinations, when the switch processing unit operates as an active system. The information processing unit 200 has a mutual monitoring processing unit 203 that checks mutual operating states between the active system and the standby system, determines that a failure has occurred when the active system does not return a response and causes the standby system to operate as an active system, and a halt processing unit that, upon operation as the information processing unit of the standby system, halts output of a packet to be a subject of information processing.

摘要： A system permitting alteration of the information processing position, where an existing information system is used, while minimizing alterations in configuration or the like, is to be provided. Intelligent nodes each having an information processing section and any desired address altering section are arranged on boundaries of a network where packets are likely to pass. This node has a flow table for recognizing as a flow a group of packets transmitted from each user's terminal, a flow status table for determining the connection state and the next destination address or the final destination address of each flow, and a module to observe the loaded state of its own information processing function. It rewrites the destination address of any flow not in a connection-established state in the flow status table to a less loaded one out of its own information processing function section or external information processing apparatus.

摘要： Disclosed herewith is a multi-plane cell switch fabric system in which each switching unit functions asynchronously with others. The system executes distribution/restoration operations without lowering the switching capacity to reorder cells that arrive in random order from a plurality of switches just as they were in original flows and packets respectively with a small hardware capacity. In the system, the distribution unit divides each variable length packet addressed to the same destination into fixed length cells and sends those divided cells by a unit of integer multiple of the number of switches. On the other hand, the reordering unit, while holding cells that arrive in random order from each switching unit (switching units 1 to M) in a receive buffer, separates only the header information from each cell and holds the header information in a retry queue. The reordering unit, upon finding the header information of a head cell of a flow in an ordering check at the time of receiving or in a retry check in the retry queue, extracts the corresponding cell bodies from the receive buffer to restore the original order of those cells in the subject packet.

摘要： In a congestion state where a specific destination in a switch fabric is congested, high priority data is allowed to pass at a low delay or high throughput while in a non-congestion state where the specific destination in the switch fabric is not congested, full use of switching bandwidth is made regardless of priority. In a switch fabric which includes plural transmitting source nodes each having not less than two output queues by the priority on a destination-by-destination basis, a switch for evenly distributing data units delivered from the plurality of the transmitting source nodes on the destination-by-destination basis, and plural destination nodes for receiving the data units from the switch, the respective transmitting source nodes assume that a relevant destination is in a congestion state when an available capacity of a receive-buffer of the switch, controlled by the respective transmitting source nodes, on the destination-by-destination basis, falls short of a set congestion threshold, thereby restricting data output from the output queues by the priority to the relevant destination up to a preset bandwidth according to priority while the respective transmitting source nodes assume that the congestion state of the relevant destination is dissolved when the available capacity of the receive-buffer of the switch, on the destination-by-destination basis, exceeds the set congestion threshold, thereby dissolving restriction on the bandwidth, according to the priority.
