Abstract:
Embodiments of the present invention disclose a service troubleshooting method, apparatus, and device, and are related to the field of communications technologies, so as to resolve a problem that due to instability of a physical parameter of an optical layer network, a service is frequently switched between a working path and a protection path at an optical layer, and an IP layer node generates a false alarm, and consequently, the service is frequently switched between currently available paths, affecting transmission of another service and stability of a transmission network. The present invention is applied to a service transmission network including an IP layer network and an optional layer network. The IP layer network includes an IP layer PCE and an IP node. The IP layer PCE receives alarm details. The IP layer PCE determines a fault type of a service transmission path in the optical layer network according to the alarm details. The IP layer PCE performs service optimization when determining that the path fault type is a real fault. The IP layer PCE does not perform service optimization when determining that the path fault type is a pseudo fault.
Abstract:
A control signaling transmission method and a device are disclosed. The method includes: receiving, by a forwarder, control signaling carrying rule matching information, where the rule matching information includes classification information and an identifier of a mobile context of user equipment; obtaining, by the forwarder according to the rule matching information, a processing rule corresponding to the rule matching information, where the processing rule includes rule description information and forwarding routing information, and the processing rule corresponding to the rule matching information is a processing rule whose rule description information matches the rule matching information; and forwarding, by the forwarder, the control signaling to a next-hop network element for the control signaling according to the forwarding routing information of the obtained processing rule. In the present invention, control signaling can be transmitted based on addressing of a mobile context of user equipment in a cloud network, signaling exchange across data centers caused when the mobile context of the user equipment is migrated between network elements can be avoided, and transmission resources of the cloud network can be reduced.
Abstract:
A packet-switched request from a first router of a network-on-chip is received. The packet-switched request is generated by source logic of the network-on-chip. Circuit-switched data associated with the packet switched request is also received. The circuit-switched data is stored by a storage element. The circuit-switched data is sent towards destination logic identified in the packet-switched request.
Abstract:
The present disclosure relates to method and device for determining performance of an intermittently used refrigerator. Performance measuring device receives time stamped temperature data from temperature sensor configured in the intermittently used refrigerator. The received time stamped temperature data is used to determine values for each of one or more predefined parameters associated with the intermittently used refrigerator. The performance measuring device determines temperature variation of the intermittently used refrigerator at predefined time intervals. Based on the determined temperature variation, additional service windows in a site comprising the intermittently used refrigerator are identified i.e. the intensity of sales in the site are identified. The determined values of each of the one or more predefined parameters and the determined temperature variation, helps in determining the performance of intermittently used refrigerator. One or more suggestions related to performance of the intermittently used refrigerator and energy consumption are provided to an end user.
Abstract:
The present invention relates to the field of mobile communications technologies, and in particular, to a deactivation method and system in a crosstalk scenario. M transceivers of a central office end send data by using M lines. The method includes: when the M transceivers are in a data transmission showtime state, if a trigger state change event is detected, switching, by N transceivers, to a deactivation execution state, to deactivate N lines among the M lines; acquiring an update coefficient used to update a crosstalk cancellation coefficient between active lines, updating the crosstalk cancellation coefficient between the active lines by using the update coefficient, and controlling the transceivers in the deactivation execution state to enter a silent or an idle state. According to the method and the system provide by the present invention, a crosstalk cancellation coefficient is updated during a process in which a line is deactivated, which can avoid a problem that deactivation of a line causes residual crosstalk of other active lines in a strong crosstalk scenario.
Abstract:
A device for a control- and information system, preferably for a ventilating system, where the ventilation system is constructed of a number of function modules (17, 18) and where the control system is provided with a central control unit (1) which via an interface (2) is connected to the different function modules with a single flat cable (3) and with a power cable (5) connecting the control unit (1) with a first connection block (4) which is mounted in a function module and that the connection from the central processing unit (1) to additional function modules and accordingly additional connection blocks (4) is done via the first connection block, which implies a simplified production and less coupling work by the construction of the complete control and regulating system.
Abstract:
A system and method can support a flooding mechanism using a multicast group in a middleware machine environment. The middleware machine environment can comprise a gateway instance that includes an external port for receiving one or more data packets from an external network. The middleware machine environment also comprises one or more host servers, each of which is associated with one or more virtual machines that can process the data packets. Furthermore, said host servers can provide virtual interfaces that belong to a virtual hub associated with the gateway instance. At least one said packet is a flooded packet that is specified with an unknown destination address when it is received at the external port. The gateway instance operates to send the flooded packet to the multicast group that operates to forward the flooded packet to one or more said host servers in the multicast group.
Abstract:
The present invention, generally speaking, provides for transmission and flow control of real-time data streams over computer networks. A real-time data stream is transmitted in data packets from a data source in accordance with a predetermined protocol over a shared network, for example. Data packets of said real-time data stream are received at a data destination connected to the local area network. The data destination determines a suggested data rate for the data source based in part on a number of data packets lost during a preceding interval of time and transmits the suggested data rate to the data source. The suggested data rate is received at the data source, which adjusts its data rate in accordance with the suggested data rate. The rate adjustment mechanism is designed such that a network segment will not be overloaded with a single isochronous data stream connection and that a disproportionate shared of the network bandwidth is not consumed by the isochronous data stream connection.
