Abstract: Method, apparatus and computer program product for appointing a leader node from a group of nodes in a data communications network. Attribute data comprising status information of one or more nodes in the group is received. At least one attribute associated with the one or more nodes in the group is identified based at least in part on the received attribute data. A given node in the group is appointed, on behalf of the group, to be the leader node when status information has been received for nodes in the group. The appointment is based at least in part on identifying at least one attribute associated with the given node that it is desirable for the leader node to possess. Appointment announcement data announcing that the given node has been appointed as the leader node on behalf of the group is transmitted.

Abstract: Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. Telephony network equipment in the telephony network receives, from the first telephony device over a signalling link, a telephony session establishment request. The telephony network equipment receives, from the first telephony device over a data link that is separate to the signalling link, a message comprising data useable by the telephony network equipment to identify the second telephony device. The telephony network equipment correlates the received telephony session establishment request and the received message. The telephony network equipment transmits, to the second telephony device, a telephony session establishment request on the basis of the correlating. The first telephony device is associated with a multi-persona user having a first persona associated with a first telephony identifier and a second persona associated with a second telephony identifier.

Abstract: Certain aspects provide a method of commissioning a virtualized network function (VNF), including: at a commissioning virtual machine instantiated in a virtualized environment of a customer network, configuring a remote access connection facility for accessing the commissioning virtual machine remotely from outside of the customer network, wherein the commissioning virtual machine has access to a virtual infrastructure manager (VIM) component of the virtualized environment; causing, via the remote access connection facility, configuration of a VNF manager component within the commissioning virtual machine; and causing, via the remote access connection facility, the configured VNF manager component to instruct the VIM component to instantiate one or more virtual machines in the virtualized environment, the one or more virtual machines being operable to perform at least a part of the VNF.

Abstract: Method, apparatus and computer program product for use in the upgrade of nodes in a group of nodes in a data communications network. One or more nodes in the group to which a given upgrade is yet to be applied are identified. A given node is selected from amongst the identified one or more nodes to which the given upgrade is yet to be applied as the leader node for the group. Data is transmitted indicating the selection of the given node as the leader node. The upgrade proceeds with the given node as the leader node.
