    摘要: There are provided measures for information exchange for cellular non-cellular interworking such as for example LTE/UTRA-WiFi interworking. Such measures may exemplarily comprise measures for reporting, e.g. from an access point of a non-cellular local-area communication system or a terminal being served in a cellular wide-area communication system, information about at least one access point of the non-cellular local-area communication system to a radio access network level of the cellular wide-area communication system, and performing, at the radio access network level of the cellular wide-area communication system, traffic offloading management for at least one terminal being served in the cellular wide-area communication system to enable offloading of terminal-related traffic from the cellular wide-area communication system to the non-cellular local-area communication system on the basis of the obtained access point information.

    摘要: One embodiment of the present invention provides a switch. The switch includes a storage device, a rule management module, a network identifier module, and a packet processor. During operation, the rule management module stores, in the storage device, a first mapping that maps a virtual network identifier of a tunnel to a rule for classifying traffic. The virtual network identifier identifies a virtualized network associated with the tunnel. The network identifier module generates, for a virtualization manager of a virtual machine, a control packet comprising a representation of the first mapping for a respective local end device. The network identifier module then obtains, from a notification packet from the virtualization manger, a second mapping that maps the virtual network identifier to an identifier of the virtual machine and an identifier of the tunnel.

    摘要: One embodiment of the present invention provides a switching system. The switching system includes a plurality of line cards, each of which includes one or more ports, a processor, one or more switch fabric cards for facilitating switching among the line cards, and a memory storing instructions for facilitating efficient hot-swapping. During operation, the switching system identifies a hot-swapping event of a first switch fabric card based on a data structure indicating the one or more switch fabric cards. The hot-swapping event indicates insertion or removal of the first switch fabric card while the switching system remains in an operational state. The switching system then determines an event type associated with the hot-swapping event and manages the first switch fabric card based on the determined event type.

    摘要: An application launcher and management framework (ALM framework) is provided for enabling and managing the execution of external applications (e.g., third party applications) on a network device. The ALM framework enables external applications to be executed and managed on a network device based upon configuration information specified for the external applications. In certain embodiments, the ALM framework enables an external application to be executed within the network device's network operating system (NOS) as if the application was provided as part of the NOS. By enabling the external application to be integrated with the network device's NOS, the ALM framework enables several services provided by the NOS to be made available to the external application.

    摘要: One embodiment of the present invention provides a switch. The switch includes a network-virtualization module, an update module, an acknowledgment module, and an election module. During operation, the network-virtualization module establishes a forwarding segment for an end device multi-homed with the switch and a second switch. The forwarding segment can be identified by a segment identifier persistent in the switch and the second switch. The update module constructs, for the second switch, a first route update message comprising an indicator value for the forwarding segment. The acknowledgment determines the indictor value in a second route update message from the second switch as an acknowledgment for the first route update message. If the switch receives the acknowledgment from a respective switch participating in the forwarding segment, the election module initiates a designated forwarder election for the forwarding segment. The designated forwarder is responsible for forwarding multi-destination traffic in the forwarding segment.

    摘要: A semiconductor device having a first stack and a second stack of device components. The first stack has a transistor switching element having a channel, a source in contact with the channel, a drain in contact with the channel, and a gate structure at least partially disposed in a space defined between and separating the source and the drain. The first stack has a source connection to the source, and a drain connection to the drain. The second stack of device components is disposed underneath the first stack and has a semiconductor substrate of a doping type the same as the drain, and a pair of electrical contacts spaced apart on the semiconductor substrate and contacting a conduction path in the semiconductor substrate extending between the pair of electrical contacts. The drain connection is connected to one of the pair of electrical contacts.
