The present document relates to cloud computing. In particular, the present document relates to methods and systems for cloud computing which enable the efficient and flexible placement of application components within a cloud. A computing device () is described. The computing device () is adapted to receive a plurality of component placement requests for one or more components () of a corresponding plurality of applications (); determine a plurality of feature vectors () from the plurality of component placement requests, respectively; wherein each feature vector () comprises vector dimensions which describe different attributes of the respective component placement request: determine a plurality of placement decisions () regarding the plurality of component placement requests, respectively: wherein each placement decision () comprises an indication of one or more executing computing devices () onto which the one or more components () of the respective application () have been placed; cluster the plurality of feature vectors (), thereby yielding one or more clusters (); wherein each cluster () comprises a default feature vector () describing the different attributes of a default component placement request; determine a default placement decision () for each of the one or more clusters; and store the one or more default feature vectors and the respective one or more default placement decisions () in a database () of the computing device ().

A method of evaluating an additional service for a device () of a user of a telecommunication system is described. The device () supports one or more basic services. The kind of basic service/s being provided by the device () is examined. An additional service that could be combined with the basic service/s already supported by the device () is searched.

The invention relates to a method for operating a symmetric network address translation NAT () setting up sessions between a user terminal (--) and a server (--). If a new session is initiated by said user terminal an external IP-address (C) and port (D) representing the desired destination server as well as a public NAT-IP address (X) are determined. Further, a public NAT-IP port is selected. Finally, the NAT sets up the new session based on an appropriate entry representing said new session in a NAT table. In order to save available public NAT-IP ports a new session according to the invention not necessarily represented by a new public NAT-IP port, but by a tuple comprising the public NAT-IP address, the selected public NAT-IP port (Y), the external IP address (C) and the port (D). A new session is set up only if there is an entry of the whole tuple identifying said new session in said NAT-table.

The invention concerns a method for providing features to the user of a telephone (HSA, . . . HSAn, HSS, . . . HSSm) that is connected to a central unit (CU) whereby, if said telephone (HSA, . . . HSAn, HSS, . . . HSSm) is currently not interconnected via the central unit (CU), said telephone (HSA, . . . HSAn, HSS, . . . HSSm) notifies the central unit (CU) at least about certain kinds of user activities, in case of such notification the central unit (CU) checks whether it is currently interconnected to another telephone assigned to the same subscriber as said notifying telephone (HSA, . . . HSAn, HSS, . . . HSSm) and in case of the existence of such interconnection, the notifying telephone (HSA, . . . HSAn, HSS, . . . HSSm) is interconnected in parallel to this interconnection, and if said notifying telephone (HSA, . . . HSAn, HSS, . . . HSSm) is not a telephone for digital communication, the other telephone is a telephone for digital communication.

A focusing device with a refractive index profile changing from the center of the focusing device towards its perimeter, is made of a material wherein the lateral refractive index distribution of the focusing device material is homogeneous and wherein the focusing device comprises holes for introducing a graded refractive index profile. This allows accurate control of the graded refractive index profile.
