Abstract: This disclosure provides new parameters for discovery request messages and discovery response messages communicated between a Network Function (NF) consumer (an NFc) (100) and a Network Repository Function (NRF) (130) in a core network. The new parameters support the discovery and selection of one or more NF services to be consumed by the NFc. More particularly, when the NFc initiates a discovery request, it identifies a particular NF service type to consume to the NRF. Included in the discovery request message are the new parameters specifying a particular set of one or more quality metrics the NRF is to report to the NFc in the discovery response message. The quality metrics include the most current measurement values for the specified NF service, but may also include historical measurement values spanning a time duration that is specified by the NFc in the discovery request message.

Abstract: Embodiments herein disclose for example a method performed by a controlling network node for handling one or more virtual network functions (VNF) in a communication network. The controlling network node initiates a setup of virtual resources for a VNF, wherein an aggregating connection point (CP), indicates a set of CPs to be connected to a same external virtual link. The controlling network node transmits configuration data to a managing function wherein the configuration data comprises an indication.

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 technique for operating a system controller of a virtualized application cluster is presented. The cluster comprises one or multiple virtual machines. In a method embodiment the system controller receives, from outside the cluster, control information defining a function associated with a virtual machine. It further receives, from the virtual machine, a request message including an identifier of the virtual machine. The method also comprises determining, based on the identifier included in the request message, the function associated with the virtual machine and booting information associated with the function. The booting information is then sent in a response message to the virtual machine.

Abstract: A flexible and context-aware delivery scheme for uniform resource locators builds on a generic representation that can be used for whichever binary content is to be delivered to a client. It can also be applied to improve the network operations of a network operator, the user's perceived quality of experience, and the costs of a content provider that does not need to encode and support different codecs and transport mechanisms.

Abstract: A technique for operating components of a virtualized application cluster with one or multiple virtual machines is described. The technique enables to identify an individual virtual machine and its function within the cluster. As such, booting information dedicated to the function of the virtual machine within the cluster can be determined and provided to the virtual machine.

Abstract: Techniques for allocation of a VLAN for a deployment by at least one VM provided on a host in a network. A VLAN manager is adapted to allocate a free physical VLAN identifier to the requested virtual VLAN identifier. The VLAN manager queries a VLAN mapping table for determining a free physical VLAN identifier. In case the physical VLAN identifier for the requested virtual VLAN identifier is in use, a procedure for determining the at least one free physical VLAN is performed. The determination procedure may be based on pre-defined zoning or it may apply a retagging after a free physical VLAN identifier has been calculated. The determined physical VLAN identifier is assigned to the requested VLAN. The VLAN switch devices are instructed about the assignment between the virtual and the physical VLAN identifier in order to apply the assignment of the data packets transported over the requested VLAN.

Abstract: A network node includes a media resources server having a plurality of coded media items for processing media item requests, a statistics database for storing media item requests received by the media resources server, and a transcoding queue manager for monitoring the media requests in the statistics database and for selectively initiating coding requests to a transcoder based on the monitored media requests and for providing the coded requests to the media resources server.
