摘要:
The invention concerns a distributed computing unit (100), comprising a processor (102) adapted to detect that a first variable (I1) indicative of the usage of a first computing resource (101) exceeds a first threshold (T1), a sender (103) adapted to send a request for information about a second computing resource (121) to a second server (120) upon detecting that the first variable (I1) exceeds the first threshold (T1), a receiver (103) receiving information about the second computing resource (121) in a response to the request, wherein the processor (102) is adapted to detect that a second variable (12) indicative of the usage of the second computing resource (121) exceeds a second threshold (T2), and wherein the sender (103) is adapted to send a request for activation of a new computing resource upon detecting that both exceed the respective threshold (T1,T2), wherein the request for information about the second computing resource (121) is sent with a predetermined delay The invention concerns a system of distributed computing units (100) and a respective method as well.
摘要:
The present document describes a system comprising at least two processing nodes 1 that are connected by a network, and an application distribution function, which automatically distributes processing components 3 of an application to be run on the system over the nodes 1. The system is configured, when a sending processing component and a corresponding receiving processing component are arranged on different nodes, to determine, based on information about the processing component 3 which receive the data, in which representation to send the data via the corresponding communication channel 4.
摘要:
A method for optimizing a communication characteristic of an application (200) comprising a plurality of processing components (202a... 202p; 204a... 204d), each of a select plurality of the processing components exchanging data directly with at least one neighboring of the plurality of processing components via at least one data link uses a representation of the application in which a data link between the processing components of the application (200) is associated to at least one weight factor and determines a statistical property of data exchanged via the at least one data link. An encoder is associated with the select processing component and a corresponding decoder is associated with the at least one neighboring processing component so that an encoded representation of the exchanged data is associated to the at least one data link based upon a determination that the statistical property fulfills a predetermined criterion.

The invention concerns conducting a video conference, wherein from a first image of a video stream recorded by a camera (145, 146, 147, 148, 165) at least a part is sent to be displayed at a remote location, wherein at least one additional image is determined and sent at least partially to be displayed adjacent to said first image at said remote location.
摘要:
A Doppler compensation method is used for radio transmission between a mobile body possibly but not exclusively a train and some base station, both mobile body and base station comprise respectively a transceiver connected to an antenna for the radio transmission. The method comprises the step of determining the direction of motion of the mobile body with respect to the active base station i.e. the base station to which a radio transmission link is just built. The method is then followed by the step to apply a constant Doppler compensation corresponding to the cancellation of the Doppler effect for a mobile body moving in the same direction at predefined limiting speed of motion (v limit ) at which a quality threshold is reached with the used radio transmission technology in the case without a Doppler compensation.

The invention concerns a method of processing a plurality of data packets in a packet switched communication network comprising at least one switching device (1) as well as a corresponding switching device. The switching device (1) comprises two or more sub-engines (21,..., 29). A control unit (7) of the at least one switching device (1) receives a data packet comprising a header (10) of a communication packet exchanged via the communication network. The control unit (7) applies at least one filter operation (50) to the header (10) and generating thereby filtered information (100). The control unit (7) maps the filtered information (100) on a hash-tag (30) according to a hash-function (300). The control unit (7) provides a tagged-header (11) by means of inserting the hash-tag (30) in the header (10) of the data packet. The control unit (7) sends the data packet to a sub-engine (24) of the two or more sub-engines (21,..., 29) according to the tagged-header (11) for further processing of the data packet.
