摘要： A network system in which a network adopting a node redundancy protocol and a network adopting an STP protocol as other protocol for managing a state of a port coexist, which is configured to manage, by the STP protocol as other protocol, a state of a port which belongs to a master node 10 and a backup node 20 forming the network adopting the STP protocol and is under the management of the node redundancy protocol and also under the management of the STP protocol, and in which the master node 10 or the backup node 20 transmits a Hello message as a control frame for monitoring a node and a link to all or a part of nodes connected to the port under the management of the node redundancy protocol, as well as transmitting a Flush message as a control frame for rewriting a forwarding database to all or a part of nodes connected to the port under the management of the node redundancy protocol at the time of switching to a master mode.

摘要： 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.

摘要： A detecting unit detects a connection of an external device to a connection port and stores the connection in a bridge state storage unit. This setting is autonomously completed by a device before an initial configuration is started by a host. A data transfer unit receives initial configuration data of a link-connection bridge from the host. Data is transferred to the linked-uplink-connection bridge with reference to the bridge state storage unit, data to a bridge which is not linked up is wasted, or an Unsupported Request is returned to the host to represent the absence of the link-connection bridge.

摘要： A network system that is part of a main system includes: a first PCI express-network bridge with a first control unit and a first PCI express adapter terminating a first PCI express bus; and a second PCI express-network bridge connected to the first PCI express-network bridge through a network. The second PCI express-network bridge includes a second control unit and a second PCI express adapter terminating a second PCI express bus, wherein the first control unit detects a destination of a packet sent from the first PCI express adapter, searches a physical address of the destination from a packet encapsulating table, and encapsulates the packet in a frame so that the frame includes the physical address, and wherein the second control unit removes the encapsulation tagged to the packet, and transfers the packet to the destination through the second PCI express bus by referring to a PCI express configuration register.
