Abstract: Methods and apparatus for fast session restoration of user sessions in a network node are suitable for latency sensitive applications. The fast session restoration techniques take advantage of the layered architecture of a network node and stores layer-specific descriptors that describe the states of corresponding service layers of a network node for an active session. When a failure of the network nodes occurs, the descriptors are used to achieve a seamless and fast session restoration.

Abstract: A persistent version-controlled is provided the enables automated configuration of VNFs/CNFs following deployment or re-deployment of VNF/CNF instances throughout the life cycle of the VNFs/CNFs. Immutable copies of NF configurations for a VNF/CNF are stored in the version controlled data storage 100. Multiple versions of a NF configuration can be associated with a common configuration reference (e.g., URL). Metadata associated with the different versions of a NF configuration indicates which of two or more different versions is the current version. The collection of different versions of a NF configuration associated with the same stable reference provide a complete history of the NF configuration, thus allowing rollback to any previous version of the NF configuration by simply modifying the metadata to mark that version as the current version.

Abstract: Fail-over protection is provided for a server cluster including a plurality of primary nodes supporting user sessions and a standby node. When the standby node determines that a primary node in a cluster has failed, the standby node configures its network interface to use an Internet Protocol (IP) address of the failed primary node. The standby node further retrieves session data for user sessions supported by the failed primary node from a low latency database for the cluster and restores the user sessions at the standby node. When the user sessions are restored, the standby node switches from a standby mode to an active mode.

Abstract: A system, method, node, virtualized network function, and computer program for preserving a media stream quality at processing of a media stream by a virtualized network function for media handling (210) is presented. The virtualized network function for media handling (210) is running in a network function virtualization infrastructure (130) hosting the virtualized network function for media handling (210). The virtualized network function for media handling (210) is managed by a virtualized network function manager (220). The method comprises to determine a media stream quality caused by the processing of the media stream by the virtualized network function for media handling (210). The method further comprises that the virtualized network function manager (220) scales the virtualized network function for media handling (210) as a result of the determining step.

Abstract: There is provided mechanisms for sharing multimedia content. A method performed by a sharing device comprises acquiring at least one of a current multimedia content segment and a current state of a screen sharing application executed by the sharing device. The method comprises determining, before a future multimedia content segment is rendered at the sharing device, a candidate multimedia content segment for the future multimedia content segment of the screen sharing application, wherein the candidate multimedia content segment is based on at least one of the current multimedia content segment and the current state of the screen sharing application and is determined from a limited set of possible candidate multimedia content segments. The method comprises generating and encoding the candidate multimedia content segment.

Abstract: Describe is a video stream mixer (60) for generating a mixed encoded video stream from an encoded primary video stream associated with a primary window, and at least one encoded secondary video stream, each associated with a corresponding secondary window that is smaller than the primary window.

Abstract: The present invention relates to a media gateway for managing a transmission of data from a first communication entity towards a second communication entity. The media gateway comprises a receiver (101) for receiving a first language indicator indicating a language associated with the first communication entity, and a processor (103) for determining upon the basis of the first language indicator and a second language indicator whether to translate the data into the language indicated by the second language indicator, the second language indicator indicating a language associated with the second communication entity.
