摘要:
The invention concerns a method for controlling a network computing cluster (101) as well as a network computing cluster (101). The network computing cluster (101) comprises one or more network computing stations (21,22,31) and one or more power autarkic network computing stations (11,12,13) supplied by one or more associated local power generators (115). The one or more power autarkic network computing stations (11,12,13) and the one or more local power generators (115) are connected with a local power network (40). In dependence on an amount of locally generated power a control signal is sent to a resource managing unit (31) of the network computing cluster (101) via a communication network (2000) which indicates the ability of the one or more power autarkic network computing stations (11,12,13) to process IT-services. Then, the resource managing unit transfers an IT-service processed by said network computing station to one of the one or more power autarkic network computing stations (11,12,13).
摘要:
A computer-implemented method, in a virtualized system comprising multiple virtual machine (VM) instances executing over physical hardware, for scaling one or more of the VM instances, the method comprising generating dependency data representing a causal relationship between respective ones of a set of VM instances indicating a direct and/or indirect dependency between the set of VM instances for a service or application to be executed by the set of VM instances, determining a current state of the set of VM instances, scaling one or more of the VM instances in the set in response to a predicted variation in system load using one or more scaling rules relating at least one load metric for the system to a predefined number of VM instances for one or more VM instances of the set to meet a performance metric for the service or application.

The invention concerns a method for transmitting data via a data link in a computer network, wherein a device at an endpoint of a section of said data link is selected (203) from devices of said computer network, a computer program adapted to process said data, is transferred (204) to said device and said data is processed (206) by said device by executing said computer program.
摘要:
A method for sending a message (8) that resides in a buffer (9) between at least one out of a plurality of sending components and at least one out of a plurality of receiving components of a cloud computing environment (1) comprising a plurality of nodes (A, B, C), wherein the sending components and the receiving components are executable on the nodes (A, B, C), the method comprising steps of: (a) adding a unique content identifier (10) to the message (8) to provide unique identification for the message (8); (b) generating a receiver list comprising components (2-7) that are allowed to use the message (8); and (c) forwarding a buffer pointer to each component (2-7) of the receiver list for enabling further handling of the message (8);
a cloud execution environment, in particular for use in the cloud computing environment (1), comprising a service router (11), provided for identifying for each message (8) potential receiving components and their location in the cloud computing environment (1), a network interface handling unit (12), provided for adding a unique content identifier (10) to a message (8) of the plurality of messages to provide unique identification for the message (8), a component scheduler (13), provided for forwarding a buffer pointer to each component of the receiver list for enabling further handling of the message (8), and a queue management unit (14), provided for generating receiver lists of components allowed to use a message (8) of the plurality of messages; a software module (15) that is executable by a cloud execution environment, for controlling an execution of steps of such a method.
摘要:
The invention concerns a method for distributing media in a computer network - at least one media source, in particular at least one camera, is adapted to capture and send at least one media stream to at least one first server, - said at least one first server is adapted to receive said at least one media stream from said at least one media source, in particular said at least one camera, and to send said at least one media stream to at least one second server, - said at least one second server is adapted to determine at least one personalized media stream depending on at least one of said at least one media stream and information about at least one desired view, in particular viewing angle or picture detail, received by said at least one second server from at least one client, and to send said at least one personalized media stream, in particular to the respective at least one client, and wherein - said at least one client is adapted to determine said desired view, in particular said viewing angle or picture detail, and send it, in particular to the respective at least one second server, and to receive said at least one personalized media stream.
