    Abstract: A method and a cloud management node for enabling usage of a virtual machine in a distributed cloud of resources for processing and storing of data. When receiving a VM image from a client with a set of files of an operating system for running the virtual machine, the cloud management node distributes the VM image to a plurality of local data centers forming the distributed cloud. In return, the cloud management node receives local identifications of the VM image from the local data centers, and creates a mapping between the received local identifications and a global identification of the VM image. The global identification is then returned to the client, thereby enabling the client to change the VM image in the local data centers by referring to the global identification in communication with the cloud management node.

    Abstract: The present invention provides a method and a caching node entity for ensuring at least a predetermined number of a content object to be kept stored in a network, comprising a plurality of cache nodes for storing copies of content objects. The present invention makes use of ranking states values, deletable or non-deletable, which when assigned to copies of content objects are indicating whether a copy is either deletable or non-deletable. At least one copy of each content object is assigned the value non-deletable. The value for a copy of a content object changing from deletable to non-deletable in one cache node of the network, said copy being a candidate for the value non-deletable, if a certain condition is fulfilled.

    Abstract: There is described a system and method of handing over a connection to a terminal from a source network element (e.g. base station) to a target network element (e.g. base station) in a packet data network when the source base station is acting as a caching server and sending content data towards the terminal in a session. A handover request is sent from the source base station to the target base station. A context data message (e.g. CXTP message) is sent from the source base station to the target base station, the context data message including session state parameters identifying the state of the session. At the target base station, the session state parameters are retrieved from the context data message and used to identify the state of the session. Content data packets are then sent from the target base station towards the terminal so as to continue the session.
