To prevent a hung-up of communications due to changes in a radio wave condition resulting from frequent displacement of the terminals and changes in a number of the terminals, and to realize switching of the radio systems adapting to the radio condition. A radio communication system comprising: a base station for providing a plurality of radio systems, and terminals for communicating with the base station through the plurality of radio systems. The base station decides a priority of the radio system on which the each terminal will communicate thereafter and transmits paging signals of one of the plurality of radio systems which includes information on the decided priority to the each terminal.

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.

A computer system having a plurality of computers connected to each other by a computer coupling mechanism. Each computer includes a processor, memory, I/O device, disk control mechanism, computer coupling network adapter, disk requirement processing section connected to a system bus, and a disk connected to a disk control mechanism. The disk requirement processing section controls the disk, in response to a processing requirement for the disk from one of the processors of the other computers, based on structural definition information. The structural definition information describes a structure of the computer system. The computer system may be a loosely-coupled computer system.

A data communication system for a computer system in which computers are mutually connected includes: each computer having an area to store a command to execute data communication on the basis of it and a buffer area to store data; a switch circuit to mutually selectively connect the computers; and a transmission permitting component, connected between the switch circuit and one of the computers, for outputting a signal to permit the data transmission from one computer to another computer; a communication component for transmitting the data received from one computer by outputting the transmission permission signal from the transmission permitting component to another computer through the switch circuit; a detecting component to detect the occurrence of an abnormality regarding the data communication from one computer to another computer; and a communication control component to abandon the data that is subsequently received from one computer by outputting the transmission permission signal in accordance with an output of the detecting component. When the abnormality occurs, the switch circuit releases another computer, thereby disconnecting one computer and another computer. When reception commands prepared in the buffer area of another computer are perfectly used, another computer abandons the packet which does not include the flag to instruct the continuous reception.

In a computer system in which nodes are connected to each other via a network, transmission and reception buffers of sender and receiver processes are prepared as resident areas in a main storage. A node of a receiver side notifies, prior to initiation of a communication, a physical address of a data reception area of the node to a node on a sender side. In the node on the sender side, the reported physical address is added to transmission data to transfer a resultant item. On the receiver side, reception data is written in a location of the main storage at the physical address. In the receiver node, the double buffering is employed to prevent an overwriting operation of another node onto the data reception area. The respective nodes achieve partial synchronization with adjacent nodes in chain, thereby automatically establishing synchronization between all nodes. A node on a receiver side notifies prior to initiation of a communication an identifier of a data reception area to a node on a sender side such that the sender node transmits data with the identifier added thereto. In the receiver node, the identifier added to the received data is compared with an identifier added to a data reception area thereof. If mismatching results, interruption is caused in a processor of the receiver node.

A system is described which enables provision of information to a stored program operating on a computer coupled to the network. A device connected to the network includes input ports for receiving information and output ports for providing the received information to a destination. The computer is coupled to receive information from the output port, which information is addressed to the computer. Within the device a flow control table holds entries which include source addresses representative of at least one source of information arriving at the device input ports, destination addresses representative of at least one of the destinations to which the arriving information is to be sent from an output port. The table entries also include action information for each address, and the action information can take the form of a program reference. When the information is received by the computer it can use the received information in execution of the stored program.

In order to execute a flow control and a congestion control in a hop-by-hop manner in a data communication among computers connected to different networks, in a data communication between a client A1 and a remote server B, a communication proxy of the remote server B is located in a local server A in an LAN to which the client A belongs. A communication packet to be routed to the remote server B is stolen (received) and passed to a transport layer. A TCP communication between the client A1 and the remote server B is divided into two; a communication between the client A1 and the communication proxy of the remote server B and a communication between the communication proxy of the remote server B and the remote server B.
摘要:
At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information 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. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.
