Abstract: Source and target service nodes and methods are described for transferring a service session for a wireless device from the source node to the target node when a service application is executed in the source node for the wireless device by the service session. In particular, the amount of application data to be transferred from the source node to the target node for a wireless device that is handed over from a first base station to a second base station can be reduced by truncating the application data by an amount corresponding to the data pending in a downlink buffer at the first base station. Thereby, the target node is able to recreate the complete application buffer from the truncated application data and data from the downlink buffer, the latter data being transferred from the first base station (206) to the second base station (208), according to a handover procedure.

Abstract: A method and a defragmentation module for defragmenting resources of a hardware system. The defragmentation module identifies a set of structures. Each structure of the set of structures partially hosts a respective set of host machines. Respective resources of each host machine of the respective set of host machines are allocated in at least two structures of the set of structures. The defragmentation module selects, from the respective resources of a host machine of the respective set of host machine, a remote resource of a first structure being different from a second structure partially hosting the host machine. A remote amount of the remote resource is less than an amount of available resources of the second structure. The defragmentation module assigns the remote amount of the available resources of the second structure to the host machine instead of the remote resource.
