摘要:
Exemplary methods for distributed multi-component service placement in a resource pool include utilizing a hierarchy of agents associated with computing resources of a cloud architecture. A root agent in the hierarchy can receive service requests specifying resource requirements and optionally location or affinity constraints, transform these into service request descriptions, and pass the service request descriptions down through the hierarchy to arrive at leaf nodes. The leaf nodes can each, perhaps in parallel, generate solution encodings indicating possible placements of some or all of the components of the service request that one or more computing devices associated with each agent can locally provide while still satisfying the resource requirements. The generated solution encodings can be passed back up and be consolidated as they flow through the hierarchy, allowing the root agent to quickly and accurately determine whether the service request may be fulfilled, and optionally place the service.

A method, resource manager, and computer program performed by a resource manager in a communications network connected to at least two hosts for enabling of resource component allocation related to the hosts, comprising determining a metric of a resource component for performance monitoring of an application at the hosts, transmitting an instruction to measure the metric to respective host, receiving a respective resource frame of the application from respective host, determining resource allocation for the application based on the received resource frames.

A method and arrangement for switching between a common media stream (301, 402) and a selective media stream (302, 403) of a media session received in a media player including a media buffer entity (300, 400). Media frames of either a common media stream or a selective media stream are received and buffered in the media buffer entity. A switch at the media buffer entity is then controlled so that the output (305, 406) of the media buffer entity is changed from delivering common media frames to delivering selective media frames, or vice versa, upon detecting a stream switching trigger frame (207, 213, 307, 405) in the received media frames.

A method, computer program and an SLA management node (100) in a computer environment (50) for monitoring and managing of resources (110) for an application (120), the method comprises determining (S100) an SLA metric for an SLA (Service Level Agreement), determining (S110) at least one dependent metric for the SLA metric, which indicates a resource (110) performance for the application (120), evaluating (S120) the at least one dependent metric's influence on the SLA metric, determining (S130) a weight for the at least one dependent metric, based on the dependent metric influence of the SLA metric, for prediction of the dependent metric influence of the SLA metric.
摘要:
A method, unit and computer program performed by a packet separation unit in a communications network for enabling of data traffic separation comprising: obtaining a traffic rule set from a rule manager, determining a complementary rule related to the traffic rule set, arranging the rules in an hierarchical order such that a received data packet will be evaluated with the rule with the most likeliness to comply with a received data packet, receiving the data packet, directing the data packet to a local shared environment.
