Abstract: Provided herein are techniques to facilitate multi-level performance tracing for a mobile network environment. In one instance, a method may include obtaining, by a mobile network, a trigger from an enterprise to initiate an underlay-level trace for a wireless device of the enterprise, wherein the trigger includes a correlation identifier that correlates the underlay-level trace with an enterprise-level trace for the wireless device and providing the underlay-level trace for a session of the wireless device by including a first trace flag for IP packets for the session and including a second trace flag for encapsulations of the IP packets for the session in which the first and second trace flag are unique to the session of the wireless device and enable elements of the mobile network to provide underlay trace information for the underlay-level trace for the session of the wireless device to a trace.

Abstract: A method to achieve fast session transfer between radio access technologies. The method includes monitoring radio performance between an access point of a wireless local area network and a user equipment in a wireless local area network, and in response to detecting that the radio performance is below a predetermined threshold, the access point signaling the user equipment to scan for and access a cellular radio service.

Abstract: Techniques for leveraging a distributed Domain Name System (DNS) infrastructure for preserving Personally Identifiable Information (PII) data by creating a hash to policy pair (HPP) database on premises at an enterprise organization. A policy engine hosted on premises at an enterprise organization applies a cryptographic hash function to metadata including PII associated with a client of the enterprise organization to generate a client hash value. The HPP is created by mapping the client hash value to a set of DNS policy instructions associated with the client and stored in the HPP database. The HPP database in published to a DNS security service, such that the DNS security service can resolve a DNS query for the client of the enterprise organization absent knowledge of the PII associated with the client by mapping the client hash value included in the DNS query to the client HPP in the HPP database.

Abstract: Techniques for mitigating network failures (e.g., SLA violations, service degradations, network outages, etc.) based on output(s) from a predictive network system. The techniques may include determining that a failure is predicted to occur in a network and determining a correlation between the failure and a previous failure that occurred in the network. In examples, the correlation may be determined using a machine-learned model. The techniques may also include determining, based at least in part on the correlation, a condition contributing to the failure. In this way, prior to occurrence of the failure, a parameter associated with the network may be altered based at least in part on the condition to mitigate or otherwise prevent the failure.

Abstract: Methods are provided in which a user device connects a participant to a collaboration session in which the participant communicates with at least one other participant using audio and/or video, which is distributed in a media stream to the at least one other participant via a respective user device. In these methods, the user device detects at least one of an object within a space that is included in the video and an audio signal and selectively filters the media stream to exclude the object or a portion of the audio signal based on at least one of participant list information, learned background information, or learned voices of participants of the collaboration session.

Abstract: A network function orchestrator (NFO) of a local area network (LAN) controller can configure multiple different tunnel endpoints in the LAN based on network traffic observed within the LAN. The NFO can monitor network traffic communicated from client devices and through access points in the LAN. The network traffic can be associated with multiple different destinations. The NFO can determine, based on the network traffic and using network topology data, network devices to serve as tunnel endpoints within the LAN. Different tunnel endpoints can be configured for use in connection with different traffic destinations. The NFO can communicate with the network devices and the access points to configure the LAN to use the different tunnel endpoints.

Abstract: A method to counter vulnerabilities associated with user equipment in operating via a 5G core architecture. The method includes monitoring a session between a user equipment and an endpoint, obtaining a vulnerability score for a vulnerability affecting the user equipment, selecting, based on the vulnerability score, a selected user plane function and a security service, accessible via the selected user plane function, to counter the vulnerability affecting the user equipment, and causing a packet flow of the session to be steered to the security service via the selected user plane function.

Abstract: Disclosed are systems, apparatuses, methods, computer readable medium, and circuits for reducing energy consumption of one or more station devices, the method including: monitoring, at a controller, energy usage by one or more station devices, on a wireless local area network (WLAN); determining, at the controller, reduction in energy consumption on the WLAN is required to meet a predetermined target; and transmitting, from the controller, a beacon that instructs the one or more station devices to enter an energy efficiency mode.

Abstract: Techniques for a low Earth orbit (LEO) satellite to route data through optimal satellite paths based on latency thresholds (and/or other QoS thresholds) for the application generating the data. The LEO satellite may identify the latency threshold from a data packet, where the latency threshold indicates an amount of time for the data packet to be relayed back down to a destination ground device. The LEO satellite determines available satellite paths through which data packets may be routed to destination ground stations. Further, the LEO satellite may determine latencies for transmitting traffic over the available satellite paths. The LEO satellite may compare the latency threshold for the data packet with the latencies of the available satellite paths, and select a satellite path that is optimal for transmitting the data packet. In this way, LEO satellites intelligently route data through satellite paths based on the type of traffic being transmitted.

Abstract: A method, computer system, and computer program product are provided for prioritizing network traffic. An indication is received at a network controller that an alarm is activated at a physical site. A request is received from a user device to join a network at the physical site that is under control of the network controller, wherein the request includes a flag indicating an identity of a user of the user device and a priority status of the user. In response to authenticating the identity of the user via an identity provider server, the user device is authorized to join the network. Based on verifying the priority status of the user using the flag and authentication via the identity provider server, network traffic for the user device is prioritized.
