Abstract: A method for a seamless transfer of a secure multimedia conference session from one endpoint device to another without a need to rekey the session is provided. In this method, a first endpoint device connects a participant to a multimedia conference session to which at least one other participant is connected and based on detecting one or more second endpoint devices within a predetermined location proximity of the first endpoint device, determines whether to transfer the multimedia conference session to a target endpoint device. Based on determining that the session is to be transferred, the first endpoint device establishes a secure pairing connection directly with the target endpoint device and provides, via the secure pairing connection, information about the multimedia conference session based on which the multimedia conference session is transferred to the target endpoint device without rekeying the multimedia conference session.

Abstract: This disclosure describes techniques for policy validation techniques relating to data traffic routing among network devices. The techniques may include processing a validation request from a controller. A validation request may include information related to a computed path for routing data traffic in a computing network. The processing may include sending one or more path requests to one or more redundant controllers, and comparing computed paths from the redundant controller(s) to the originally computed path. The techniques may include generating a validation response based on comparing the computed paths. In some examples, the techniques may further include determining a health score for the controller. Policy validation techniques may improve data traffic routing among network devices by helping to ensure valid policies are produced.

Abstract: This disclosure describes techniques for enhanced segment routing across computer networks. The routing of data traffic may be enhanced by accounting for additional considerations, beyond typical network parameters, when selecting segment routes via which to route the data traffic. For instance, a service provider (SP) may wish to consider business priorities when selecting a segment route to another SP. The techniques described herein include mechanisms for gathering and/or receiving information regarding business priorities, analyzing the business priorities, and determining a segment route. As such, through accounting for additional considerations beyond typical network parameters, enhanced segment routing may potentially improve client service and network operations.

Abstract: A method is provided for use in a network that includes a plurality of user plane functions that perform processing of user plane traffic sessions from one or more mobile wireless user devices. The method includes periodically monitoring resource utilization of the plurality of user plane functions to estimate a resource utilization level of respective user plane functions. Based on the periodically monitoring, the method further includes storing for the respective user plane functions a resource utilization level indicator for each of the respective user plane functions according a resource utilization level of the respective user plane functions. User plane traffic sessions for a given tracking area are re-assigned (moved) among the plurality of user plane functions based on the resource utilization level indicators for the respective user plane functions to achieve a desired quality of experience for the user plane traffic sessions.

Abstract: Wireless infrastructure upgrading may be provided. An Access Point (AP) may be caused to decline new association requests received from client devices not associated with the AP. Next, the AP may be caused to instruct client devices associated with the AP that detect a signal level from the AP to be below their roaming margin to roam away from the AP. Then the power of the signal level from the AP may be decreased by a predetermined amount. Causing the AP to instruct client devices associated with the AP that detect the signal level from the AP to be below their roaming margin to roam away from the AP and decreasing the power of the signal level from the AP may be repeated until the power of the signal level from the AP is at a predetermined level.
