Abstract: A host clock value may be provided to a client device. An Access Point (AP) may obtain a Timing Synchronization Function (TSF)-based time stamp. Next, the TSF-based time stamp may be placed in an Information Element (IE) that was intended to contain follow up information. The IE may then be transmitted.

Abstract: The disclosed technology provides solutions for performing rapid authentication and authorization for distributed containerized microservices. In some aspects, a process of the technology can include steps for: associating a service type with a set of microservices or service pods, detecting deployment of a first microservice on a first host, and receiving an authentication and authorization state from a first virtual network edge (VNE) of the first host. In some aspects, the process can further include steps for distributing the authentication state to a second VNE on a second host, wherein the authentication state is configured to facilitate authentication of one or more subsequent microservices instantiated on the second host by the second VNE. Systems and machine readable media are also provided.

Abstract: In one embodiment, a device may obtain sensor measurements from an environmental sensor of an access point. The device may obtain traffic telemetry data regarding network traffic handled by the access point. The device may generate, based on the sensor measurements and the traffic telemetry data, a sampling configuration of the environmental sensor of the access point. The device may cause the access point to collect additional sensor measurements from its environmental sensor according to the sampling configuration.

Abstract: A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block. The mapping information is communicated, processed, and stored once for the complete block, instead of for every new data connection. This process reduces processing, communication, and storage requirements.

Abstract: A Third Generation Partnership Project (3GPP) based network, such as an enterprise private 3GPP network, is operative to provide a guest onboarding of a device using a realm-based discovery of an identity provider and a mutual authentication of identity federation peers. A secure connection may be established between the peers so that the device may be authenticated based on credentials associated with a Subscriber Identity Module (SIM) provided by its Mobile Network Operator (MNO). Credentials may be extended to those associated with embedded SIMs (eSIMs), digital certificates from private enterprises, login and passwords, and identities from a wide range of identity providers. After device authentication, the 3GPP-based network is operative to select and enforce access policies according to an identity or other attribute of the device.

Abstract: Techniques to eliminate duplicate packets from a stream of packets. A method includes receiving a packet, hashing elements of the packet to obtain a packet partial signature, generating an action data value by appending, to the packet partial signature, unhashed packet information, accessing a hash store location in a hash store based on the action data value, determining, based on data stored at the hash store location, whether the packet is a duplicate of a previously-received packet, and based on whether the packet is a duplicate of a previously-received packet, one of allowing and preventing one of the packet and a copy of the packet to reach a downstream network node.

Abstract: Methods are provided in which a recording service obtains a multimedia stream along with metadata of an established collaboration session in which at least two participants collaborate via respective user devices. The recording service identifies each of the at least two participants of the established collaboration session based on the metadata and obtains an individual recording privacy control associated with each of the at least two participants based on identifying. The recording service further generates a recording of the established collaboration session restricted by the individual recording privacy control for each of the at least two participants.

Abstract: A waveguide delay-based equalization (WDEQ) system is described. The WDEQ system provides a delay in waveguides of the system and electrical signal summing in a differential transimpedance amplifier (TIA) which increases the performance (e.g., bandwidth, etc.) of the optical receiver. The WDEQ system includes an optoelectronic circuit with a directional coupler, a first photodetector, at least two transistors connected to the first photodetector, an optical delay, and a differential transimpedance amplifier (TIA).

Abstract: Techniques and systems described herein relate to shared storage systems across network devices to use unused storage space and provide backup and additional storage for devices as needed. The techniques and systems include determining availability data describing available storage locations and amounts on network devices, compiling such data at a network controller, and communicating the availability data to the network devices. The network devices then directly communicate with each other to store data remotely as needed.

Abstract: A method of transmitting an encrypted data packet includes, with a processor, in response to receiving the encrypted data packet, executing an extended Berkeley packet filter (eBPF) application at an express data path (XDP) hook point located within a kernel space, determining whether the encrypted data packet is to be processed via a trusted application (TA) within a trusted execution environment (TEE) based on an analysis by the eBPF application, and identifying application intelligence data defining packet forwarding decisions based on a manner in which the encrypted data packet is processed.
