Abstract: A system analyzing apparatus obtains a message group including a message ID, a protocol, a type, and a transmission time of messages transmitted/received in a system where a hierarchical structure of protocols is defined. The apparatus detects pairs of a request message and a response message of the same message ID from the obtained message group. The apparatus identifies a request time and a response time of each of the detected pairs. The apparatus searches for a child-layer pair that has a request time and a response time between the request time and the response time of a parent-layer pair arbitrarily selected from among the pairs and that has a protocol in a layer lower than the protocol of the parent-layer pair on the basis of the identified result. The apparatus outputs the found child-layer pair as a candidate pair having a call relationship with the parent-layer pair.

Abstract: Any packet loss is detected very quickly by means of only a series of sequence number in a multi-path environment where a transmitter and a receiver are connected to each other by way of a plurality of networks when no inversion of sequence arises in any of the networks. A communication apparatus includes a plurality of sequence buffers arranged at each network to accumulate packets until a sequence acknowledgement and an absence detecting section adapted to determine the occurrence of an absence of a packet when one or more packets are accumulated in all the sequence buffers. With this arrangement, the absence detecting section of the receiver monitors the packets staying in the sequence guaranteeing buffer arranged in each of the network, paying attention to the characteristic that packets are stored in the sequence buffers of all the networks when a packet loss takes place.

Abstract: A packet communication device autonomously selects an appropriate operation mode according to a connection environment to an external device before a service of the device is started. When the device is connected to the external buses, connection interface units notify an external device discrimination unit of connection of the device. The external device discrimination unit issues a polling packet to the connected device, discriminates the connected external device on the basis of the response packet, and notifies an operation mode switching unit. The operation mode switching unit selects an operation mode conforming to a connection environment of the packet communication device to the external device and switches the operation mode of the device to the mode.

Abstract: A local-memory side data transfer unit increments the number of addresses, reads out data from a local memory, and stores the data into a cache memory of a remote-memory side data transfer unit. For preventing data mismatching with the local memory from being stored into the cache memory, a cache clearing operation is executed in units of an elapse of a round trip time period for data transfer between the local memory and the remote memory. Alternatively, the cache clearing operation is executed upon receipt of a signal notifying data transfer of data stored at a specified address.

Abstract: An I/O equipment sharing system includes CPUs, a plurality of route complexes coupled to the CPUs, upstream PCI Express-bridges coupled to the route complexes, downstream PCI Express-bridges coupled to the upstream PCI Express-bridges through a network, and I/O equipment coupled to the downstream PCI Express-bridges. In the above configuration, the I/O equipment are shared between the CPUs using the identifiers of the network (for example, Ethernet VLAN IDs), the identifiers are set so that they do not overlap between the respective CPUs and necessary I/O equipment is set to a set identifier. Further, an identifier is set to a plurality of the same I/O equipment required by the respective CPUs.

Abstract: A virtual PCI Express device 1600 indicates the presence of a pseudo I/O device in a PCI Express initial configuration cycle to reserve a resource space for a device anticipated to be installed in the future, and when an I/O device 1400 is inserted into an unoccupied slot 1605, a virtual PCI Express device control logic 1602 notifies a downstream PCI-PCI bridge 1504 via a hot-plugging control line 1601, and the downstream PCI-PCI bridge 1504 generates an interrupt to a CPU 1100 to notify it of insertion of the I/O device 1400 in conformance with the procedure for hot plugging defined by the PCI-SIG Standards, and configuration software 1000 invoked configures the inserted I/O device 1400.

Abstract: A PCI Express switch which connects a plurality of peripheral devices to an arbitrary one of a plurality of CPUs through an Ethernet is constituted by a plurality of upstream and downstream PCI Express-network bridges, an Ethernet switch, and a system manager. Each of the upstream and downstream PCI Express-network bridges includes a PCI Express adapter which terminates a link of a PCI Express bus, a network adapter which terminates a link to the Ethernet switch, and a control unit which encapsulates a TLP in a frame, the destination of which is a MAC address of a bridge to which the destination is connected to transmit and receive the frame. Because the switch according to the present invention comprising a plurality of upstream PCI Express-network bridges and a plurality of downstream PCI Express-network bridges connected to the plurality of upstream PCI Express network bridges through a network is equivalent to a conventional PCI Express switch, it is needless to change a conventional PCI software.
