Abstract: Systems, methods, apparatuses, and computer program products for virtualized network function (VNF) decomposition are provided. An embodiment of the invention includes to first decompose the Network Function into smaller blocks: application, platform, and resources (i.e., compute, network, and storage), then manage the decomposed application and platform parts by separate entities (e.g., EM/VNFM). This decomposition may be applied to the Network Elements (i.e., the current building blocks of telecommunication networks) and to the VNFs.

Abstract: Various communication systems may benefit from the appropriate selection of monitored parameters. For example, certain wireless communication systems may benefit from virtual network function indicator selection mechanisms that can be applied by a virtual network function manager. A method can include preparing an indicator declaration for an indicator value of a virtualized network function descriptor. The method can also include providing, in the indicator declaration, an indication of importance of the indicator value.

Abstract: Messages that cannot be delivered into the mailbox of the message addressee in networked message memory units (for example, given malfunctions) are transmitted back into the mailbox of the message sender after a predetermined time. Each message is provided with message-associated information (for example, name of the message sender, time at which the message was generated). In order to avoid the same message from being repeatedly stored in the memory unit of the message sender given multiaddress transmission of one of the same message to a plurality of message addressees and given non-deliverability of the messages, the message-associated information of fed back messages are checked for identity and are not stored if identified.
