摘要： This invention provides dynamic balance of the traffic among data processing devices interconnecting networks and thereby improve the networking performance. For network traffic flowing between a first network and a second network, the traffic is distributed among the data processing devices that act as routers according to the traffic amount. An algorithm for balancing the traffic is used to select appropriate data processing devices as routers.

摘要： At each network node, a packet classification unit (10) makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor (20) and transfer other packets directly to a routing processor (5). Processing history information (140) indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table (24). Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.

摘要： A network communication method (and system) enables received data to be transferred directly to the user data region, thereby eliminating the need to perform data copy operations. Packets are each provided with received region assignment information (port ID) for showing the region in which the packet is to be received and/or division information for dividing the packet. The region which is to receive data contained in the packet is determined from a port table and conversion tables, and the packet data is transferred to the region directly.
