摘要:
A switching node for use in connection with a computer network includes an input interface, a buffer and a control element. The input interface receives cells from at least one input communication link. The buffer buffers selected cells prior to transmission over at least one output communication link. The control element selectively enables cells received by said input interface to be buffered in said buffer. The control element discards cells if the cell occupancy of the buffer exceeds a predetermined threshold level and a credits value indicates that the switching node has loaded a number of cells into the buffer for transmission which exceeds a cell loss ratio guarantee provided by the switching node.

A system and a method for providing an emulated network including a plurality of emulated networking devices, in which a number of network node executable images are employed. Each of the network node executable images corresponds to one of the emulated networking devices. The emulated networking devices represent physical networking devices, such as optical switches. A portion of each of the network node executable images is operable to execute without modification on a physical networking device. Each of the network node executable images includes a number of program components, such as a topology related program component for maintaining a representation of the topology of the emulated network, a trunk manager program component for maintaining at least one emulated trunk between the corresponding emulated networking device and an adjacent other emulated networking device, and a circuit manager program component operable to maintain at least one emulated circuit between the corresponding emulated networking device and another one of the emulated networking devices. Various numbers of network node executable images may be executed on a single emulator machine, and multiple emulator machines may be employed to execute a single network node executable image.

A method of transmitting a message between user equipment and network equipment, user equipment and network equipment are disclosed. The method of transmitting a message between user equipment and network equipment in which the message comprises a message header and a message payload, the message header having a plurality of fields, comprises the steps of: setting an indicator field in the message header to indicate that a report providing scheduling information is included in the message payload; setting a secondary indicator field in the message header to indicate that, for at least some values of the secondary indicator field, an alternative report having alternative scheduling information is included in the message payload; and transmitting the message header and message payload. This enables alternative reports to be transmitted from the user equipment without reducing the number of allocatable logical channels or MAC CE types.

An approach for managed instant communication (or chat)-based helpdesk services. An inquiry for a support service is received, at a helpdesk management platform, from a customer requesting assistance, the inquiry including one or more parameters defining the support service. A response is generated to the inquiry based on the one or more parameters, the response indicating a plurality of helpdesks associated with at least one service provider. An instant communication session is established between the customer and one of the helpdesks. The instant communication session is placed into a queue for an agent associated with the one helpdesk.

The invention proposes a method and an apparatus for transmitting a buffer status report in a wireless network, where a user equipment is configured with a plurality of component carriers, the user equipment obtains an amount of data to be transmitted after respective media access layer protocol data units corresponding to the respective component carriers are generated, generates the uplink buffer status report message according to the amount of data to be transmitted, and reports the uplink buffer status report message to a base station serving the user equipment. The invention address the problem of how to report buffer status information when there are a plurality of media access layer protocol data units in a transport time interval. With the solution of the invention, the base station can definitively know how many uplink resources can be allocated for the user equipment to guarantee more efficient scheduling.

According to one embodiment, a spin-torque oscillator includes a non-magnetic unit, one or more first magnetic unit, and a second magnetic unit. The non-magnetic unit is formed of a non-magnetic body. The one or more first magnetic unit is connected to the non-magnetic unit and generates a pure spin current indicating the flow of the electron spin that does not accompany an electric charge current. The second magnetic unit is connected to the non-magnetic unit in a manner such that a distance between the second magnetic unit and the first magnetic unit is shorter than a spin diffusion length indicating a distance that an electronic spin polarization is maintained in the non-magnetic unit. The second magnetic unit oscillates by the pure spin current.
