    Abstract: A method of operating a telecommunications network (100), said telecommunications network being accessible to a User Equipment (UE) (102) and comprising a cellular telecommunications network (104-2) and a fixed-access telecommunications network (104-1), the method comprising the steps of: providing a set of user plane functions for processing user traffic for the UE, said set comprising at least two user plane functions; providing a combined user plane function (210) for processing user traffic for the UE according to the set of user plane functions; following establishing a network connection between the UE and the cellular telecommunications network via the fixed-access telecommunications network (510), identifying inefficient routing of user traffic associated with the UE (520), said inefficient routing comprising routing user traffic to at least the set of user plane functions; in response to identifying inefficient routing, re-routing user traffic associated with the UE to the combined user plane function so as to process the user traffic at the combined user plane function instead of at the set of user plane functions (530).

    Abstract: A communication control device included in a user plane of a mobile communication system in which a control plane and the user plane are separated includes: a packet transfer unit that transfers a packet to a network apparatus; a reception unit that receives, from the control plane, a basic DSCP being a DSCP set to each QoS flow by the control plane according to a QoS class; and a measurement unit that measures a use band amount of the packet for each of the QoS flow, and the packet transfer unit determines a new DSCP being a DSCP to be stored in the packet to be transferred, based on the basic DSCP and the use band amount of the QoS flow to which the packet to be transferred belongs, and stores the new DSCP in the packet to be transferred to the network apparatus.

    Abstract: Techniques and architecture are described that utilize switchport protected flags to provide switchport protected functionality across network devices, e.g., switches, routers, etc., in fabric networks. For example, a first port of a first network device of a fabric network receives a packet from a first host destined for a second host. The second host is onboarded to the fabric network via a second port of a second network device. It is determined (i) if a first protected flag associated with the first port of the first network device is set as true and (ii) if a second protected flag associated with the second host is set as true. Based at least in part on (i) the first protected flag associated with the first port being set as true and (ii) the second protected flag being set as true, the first network device drops the packet.
