The data processing management system includes a queue deployment system that deploys a queue with a processing description of stream processing having a branch instruction being an input. The queue deployment system designates processing to be preferentially executed for the processing description, measures throughputs in respective processing after the branch instruction, and obtains branch proportions that at which the respective processing after the branch instruction is executed. The queue deployment system then computes deployment costs in a case of deploying a queue between the branch instruction and the respective processing after the branch instruction, for combinations of the respective processing after the branch instruction using the throughputs and the branch proportions, and outputs a queue deployment pattern for preventing a decrease in a throughput of the processing to be preferentially executed among the respective processing after the branch instruction.

Information linkage system and information management method

A computer system for controlling data linkage achieves higher rate data transfer between a first system that performs operations and a second system that acquires data regarding the operations reduces influence on the operations and between the systems. The first system includes a storage unit that manages resources storing data and a control unit that controls data transfer and the second system includes a data acquisition unit. The control unit calculates cost that represents a load of the first system with respect to each of multiple data transfer schemes, determines an applicable data transfer scheme based on the cost, and notifies the second system of that scheme. The data acquisition unit manages states associated with the determined data transfer scheme and sends a request to acquire data from resources based on the determined data transfer scheme and the states.

It is intended to provide a frame transfer apparatus for transferring an LLDP frame to reduce a traffic load of the LLDP frame periodically sent for survival confirmation. The frame transfer apparatus within a network sends the LLDP frame by converting a TTL of the LLDP frame to be transferred to its maximum value of 65535. Also, the frame transfer apparatus makes the survival confirmation for a terminal, and sends as proxy the LLDP frame in which the TTL is set to 0, in place of the terminal, at a moment of expiration of the TTL, whereby the disconnection of the terminal from the network is appropriately notified to the other terminals. Thereby, the load of the LLDP frame periodically sent for survival confirmation within the network can be reduced.

When streaming transfer of voice or image is performed using a real time streaming protocol (RTSP), streaming transfer of a high bit rate is enabled even in an environment of using network address port translation (NAPT) and network address translation-protocol translation (NAT-PT). When a SETUP message of RTSP is received, a port number having the same number of digits as a client port number notified by a client is assigned from a port number pool, and is registered in an NAPT table. The SETUP message is rewritten with the port number.

The present invention provides a network relay apparatus capable of assuring the prevention of occurrence of order reversion of packets within flows and shifting a packet distribution destination according to load information. The network relay apparatus includes: a packet distribution processor for distributing input packets to thereby achieve load dispersion of packet processing; a statistical information collector for regularly collecting load conditions of respective packet processors; and a distribution information holder for retaining information for specifying the packet distribution destinations upon distribution of the packets. Information about the load conditions of the respective packet processors are compiled and distributed to the packet processor smallest in load. Timing provided to change the packet distribution destination is assumed to be given when a processing waiting queue does not include a packet corresponding to its flow.
