Abstract: Traffic is processed in a virtualised environment comprising: (i) a physical underlay network; (ii) a first overlay network (an overlay of the physical underlay network and associated with a first set of network addresses, IP1); (iii) a second overlay network (an overlay of the first overlay network and associated with a second set of network addresses, IP2); and (iv) virtualised applications each having an execution environment and being associated with at least one network address in each of the first and second sets of network addresses, IP1 and IP2. In the execution environment of a first virtualised application: (i) traffic communicated from the first virtualised application to the first overlay network is encapsulated; and/or (ii) traffic communicated from the first overlay network to the first virtualised application is decapsulated. Tenant separation processing is performed outside the execution environments of the virtualised applications.

Abstract: In a telecommunications network including at least a user device and a network node separated by at least a packet-switched part of the telecommunications network, the user device including a primary jitter buffer having a constant packet play-out rate, the network node including a secondary jitter buffer, incoming packets destined for the user device are received and passed through the secondary jitter buffer of the network node downstream towards the primary jitter buffer of the user device. The departure times of packets passing through the secondary jitter buffer of the network node downstream towards the primary jitter buffer of the user device are monitored. On the basis of the monitoring and one or more known characteristics of the primary jitter buffer, an estimate of a current state of the primary jitter buffer is maintained. Operation of the secondary jitter buffer is dynamically controlled according to the maintained estimate.

Abstract: Measures for use in operating a subscriber device in a network. An audio call communication session is conducted between the subscriber device and an audio call client of a remote user device. The audio call communication session includes the transfer of audio data between the subscriber device and the audio call client of the remote user device. During the audio call communication session, transmittal, to a user interface associated with a user of the remote user device, of information associated with switching communication from the audio call client of the remote user device to a web browser client is caused. A real-time media data communication session is established between the subscriber device and the web browser client. Real-time media data is transferred between the subscriber device and the web browser client instead of audio data between the subscriber device and the audio call client of the remote user device.

Abstract: Network slicing allows a network operator to divide up their network into different network slices. The operator can assign specific users or classes of users to 5 each slice. Network functions (NFs) comprising a network slice may be placed in different locations in a network (for example, nearer the network edge), may be configured or tuned for different traffic profiles, and/or may be implemented by different vendors from those in other slices. A network, configured to perform network slicing, receives information from a Session Management Function, SMF, relating to a 10 given packet data session belonging to a given network slice. Based on the information received from the SMF, the network signals to a UPF instance that the given packet data session belongs to the given network slice.

Abstract: Maintaining a list of communication session servers which are currently in an active state and which are currently in a failed state, and which are currently responsible for providing communication services to which subscribers. Receiving a query in relation to a communication session involving a subscriber. In response to the list indicating that a communication session server which is currently responsible for providing communication services to the subscriber currently has an active state, responding to the query with an identifier for the communication session server. In response to the list indicating that the communication session server currently has a failed state, conducting a responsibility transfer operation to transfer responsibility for providing communication services to the subscriber from the communication session server to a different communication session server and responding to the query with an identifier for the different communication session server.
