摘要:
A technique for creating a resource in a cloud computing system is described. A method implementation of this technique comprises providing a plurality of predefined base resource descriptions, each base resource description defining a base resource in the cloud computing system and specifying one or more properties of the base resource, providing a plurality of predefined modifiers, each modifier being applicable to a resource in the cloud computing system to add, remove or change a property of the resource, wherein each modifier is associated with metrics information, and receiving a resource request indicating one or more desired properties for a target resource in the cloud computing system. In response to receipt of the resource request, a selection operation is performed to select a base resource description and one or more modifiers that are to be applied to the base resource corresponding to the selected base resource description to create the target resource in the cloud computing system, wherein the selection operation is based on the metrics information. In a next step, the selected base resource description is deployed to create the corresponding base resource in the cloud computing system, and application of the selected modifiers to the base resource in the cloud computing system is triggered to create the target resource.

摘要:
A method for a client node (D100) to access an information object (102) located at a node (D500) of a secured network (120) via a network of information (100) wherein information objects (102) are identified by information object identities (IDObj, ID′Obj) and wherein nodes are identified by locators (LGW, LObj), wherein the following is performed at a routing node (D102): —receiving from the client node (D100) an information object identity related to the information object (102), —sending the information object identity to a resolving node (D400) of the network of information (100), the resolving node (D400) being capable of initiating a procedure for sending to the routing node (D102) a locator of a gateway node (D200) interfacing the network of information (100) and the secured network (120), —receiving the locator of the gateway node (D200), —sending a request for the information object (102) to the gateway node (D200) according to the locator, —receiving the requested information object (102) from the gateway node (D200), and —sending the information object (102) to the client node (D100).
摘要:
A method for control ling information object (102) usage in a network of information (100) wherein information objects (102) are identified by information object identities and locations of the information objects (102) are indicated by location pointing information, the method comprising receiving (5b) an encrypted information object (102), sending (7) to a resolution node (D200) a request for location pointing information of a key issuing node (D300), the request comprising an identity of the received information object (102), receiving (8) the location pointing information of the key issuing node (D300), sending (9) to the key issuing node (D300) a request for an access key (104) for decrypting the encrypted information object (102), the request comprising the identity of the received information object (102), receiving (11) the access key (104), and decrypting (12) the received encrypted information object (102) with the received access key (104).

摘要:
A method for a client node (D100) to access an information object (102) located at a node (D500) of a secured network (120) via a network of information (100) wherein information objects (102) are identified by information object identities (IDObj, ID′Obj) and wherein nodes are identified by locators (LGW, LObj), wherein the following is performed at a routing node (D102):—receiving from the client node (D100) an information object identity related to the information object (102),—sending the information object identity to a resolving node (D400) of the network of information (100), the resolving node (D400) being capable of initiating a procedure for sending to the routing node (D102) a locator of a gateway node (D200) interfacing the network of information (100) and the secured network (120),—receiving the locator of the gateway node (D200),—sending a request for the information object (102) to the gateway node (D200) according to the locator,—receiving the requested information object (102) from the gateway node (D200), and—sending the information object (102) to the client node (D100).
摘要:
A method for controlling the transmission of a media stream comprising a plurality of consecutive stream elements Is described. The method comprises the step of obtaining (32) a media description of the media stream, the media description indicating an initial element of the stream elements. A request for the initial stream element is sent (34) and a session control procedure is initiated (36) for a session. The media stream is associated (38) with the session in the session control procedure. The transmission of a subsequent element of the stream elements is controlled in accordance with a control rule of the session. Devices and further methods embodying the invention are also described.

摘要:
Methods and devices for providing a media description of a media stream to a client are described. The client is subscribed to a media description delivery service. The media description delivery service comprises a media description delivery rule. A request for a media description delivery is sent to a media server. From the media server a media description is received. It is verified that the received media description complies with the media description delivery rule and if the verification is in the affirmative, a delivery of the media description is initiated to the client.

The invention relates to techniques for controlling a delivery of streaming content in a point-to-multipoint (‘PTM’) enabled network (100). A method aspect of such a technique comprises the steps of sending one or more adjustment instructions for achieving a buffer overlap in content buffers (132-136) of a plurality of terminal devices (102-106) each receiving content via a point-to-point (‘PTP’) distribution (116-120), and initiating, following the sending of the adjustment instructions, a PTM distribution (142) for at least some of the plurality of terminal devices.
