摘要： In at least some embodiments a system may comprise a first master device, a second master device, a redundancy manager coupled to the first and second master devices, and a slave device coupled to the redundancy manager. The redundancy manager is operable to receive a first data stream from the first master device and a second data stream from the second master device. The redundancy manager is further operable to selectively forward one of the first and second data streams to the slave device according to a prioritization of factors calculated to optimize an amount of valid communication to the slave device.

摘要： A management system of blade server is described. The system comprises at least two management blades and a middle interface. The two management blades become one master management blade to control directly the system and a slave management blade prepared to control the system when the system is turned on. The middle interface installs server blades, switch blades and the management blades thereon according to the actual request. A COM port is a main interconnecting line between the management blades and a LAN port is an auxiliary interconnecting line. The system can directly exchange the master management blade and the slave management blades by way of application software. The slave management blade is promoted to master management blade immediately when the original master management blade fails to work.

摘要： A method and system for operating a bus master on a field bus on the basis of the master/slave principle in the event of a fault. The field bus has at least one slave connected to it and the bus master runs a separate state table for each connected slave. The state table stores the operating state of each individual slave and each state table is deleted when initialization takes place for the first time. In the event of a fault, the bus master is reinitialized such that a check is run to ascertain whether full initialization has taken place for each connected slave as assumed, and, if it has, the content of each state table is retained in unmodified form, and, if it has not, the state table for the affected slave is deleted and the bootstrap initialization is imposed.

摘要： Messages consisting of an arbitration field followed by a data field circulate in a single-channel bus system. The stations comprise a storage element for an intended delay time between a locally formed signal transition and a resultant detectable signal transition. The stations also comprise a continuous sequencer for the successive bit cells. When a signal transition is detected, the sequencers are loaded with the position of the storage element, so that they are synchronized. In the case of a transmission operation, the delay is measured, so as to update the contents of the storage element.

摘要： An automation system has a plurality of subscribers including a first master unit, first distributor, second master unit, second distributor, and at least another subscriber unit. First and second transmitting/receiving devices of the first and second distributor are connected via a ring-shaped data bus. In a first mode, the first distributor forwards telegrams received from the first master unit to the first transmitting/receiving device, and forwards telegrams received by the second transmitting/receiving device to the first master unit. The second distributor also forwards first telegrams received by the first transmitting/receiving device to the second transmitting/receiving device. In a second mode, the second distributor forwards telegrams received by the second master unit to the second transmitting/receiving device, and the second distributor forwards telegrams received by the first transmitting/receiving device to the second master unit. The first distributor also forwards telegrams received by the second transmitting/receiving device to the first transmitting/receiving device.

摘要： Packets received by a network device are assigned to packet flows defined by shared packet characteristics. The packet flows belong to a first category containing packet flows that are to be granted access to the shared resource periodically and with a fixed time interval between subsequent grants of access to the shared resource, or a second category containing packet flows not included in the first category. A periodic schedule that allocates the shared resource to the packet flows in the first category is determined. The periodic schedule includes one or more empty time slots during which the shared resource is not granted to any packet flow in the first category. Access to the shared resource is granted to packet flows in the first category according to the periodic schedule, and is granted packet flows in the second category during the empty time slots in the periodic schedule.

摘要： A communication apparatus that forms, in a train in which fixed formations are coupled, a backbone network relaying signals between branch networks formed in the fixed formations with another communication apparatus that is made redundant, includes: a VRRP functional unit that, when operating as a master, periodically transmits an alive monitoring frame to another communication apparatus operating as a backup via the branch network, and, when operating as a backup, receives an alive monitoring frame transmitted from another communication apparatus operating as a master via the branch network; a port-malfunction detection unit detecting malfunction of the port to which the branch network is connected; and an alive determination unit that, when operating as a backup, detects whether another communication apparatus operating as a master has malfunctioned based on an alive-monitoring-frame reception result from the VRRP functional unit and a malfunction detection result from the port-malfunction detection unit.
