Abstract: A Network Functions Virtualisation Management and Orchestration system, NFV-MANO, for managing resources in a Network Function Virtualisation Infrastructure, NFVI, has elements (NFVO, VNFM) for orchestrating and managing virtual resources to provide a network service and has an allocation element (VIM) for managing an allocation of physical resources for the virtual resources. One of the elements for orchestrating (NFVO, VNFM), obtains (210) information about which of the virtual resources could be affected by a planned adjustment of the allocation, and determines an impact (220) of the planned adjustment on a network service, based on this information. An indication based on the impact on the network service is sent (230) to the allocation element (VIM), which implements the planned allocation according to the indication. This can help enable a better trade off between allocation efficiency and quality of network service.

Abstract: A method is described for handling of connections between a client (200) and a server (214) via a communication network. A connection (206) is established over a first access point (202) which is associated with the server (214). At least one further access point (204) associated with the server is defined. A failure of the connection (206) over the first access point (202) is detected and a second connection (208) between the client (200) and the server (214) is established over the further access point (204). A third connection (212) between the client (200) and the server (214) over the first access point (202) is further established. The establishment of the third connection (212) is executed with a delay compared to the establishment of the second connection (208).

Abstract: A method is described for access to a directory by an application (410). A function library (412) handles a first request from the application for fetching the information from a server. The first request is forwarded from the function library (412) to the server by a client module (414). A request identifier (420) is sent from the function library to the application when the first request is forwarded to the server. A response signal (422) to the first request is sent from the server and received by the application. The response signal comprises a response identifier. The response identifier is checked to match the response signal (422) to the first request. A function from the function library is called (424) by the application for decoding the response signal. The decoded response signal is returned (426) from the function library to the application. A device and a program are also described.
