Abstract: Embodiments provide techniques for transmitting data packets across a deterministic Ethernet network. Embodiments receive, at a first device in the deterministic Ethernet network, a deterministic binary schedule specifying timing information for transmitting data fragments relating to a plurality of data flows. Data packets to transmit to a destination device within the deterministic Ethernet network are received at the first device. Embodiments include fragmenting each of the data packets into two or more fragments and encoding at least one of the two or more fragments for each of the data packets with a respective sparse graph code. The encoded fragments are transmitted to the destination device, across multiple paths through the deterministic Ethernet network, according to timing information specified in the deterministic binary schedule.

Abstract: Techniques for wireless communication are disclosed. These techniques include defining a message schedule for fine time measurement (FTM) at a first wireless access point (AP). The techniques further include broadcasting the message schedule to a plurality of wireless stations (STAs) from the first AP. The techniques further include receiving, at the first AP, a plurality of FTM messages from the plurality of STAs, the messages transmitted by the plurality of STAs based on the message schedule. The techniques further include determining a distance between the first AP and each of the plurality of STAs based on the plurality of FTM messages.

Abstract: In one embodiment, a mobile node in a wireless network determines a physical location of the mobile node. The mobile node obtains telemetry data. The mobile node makes a comparison between the physical location of the mobile node and a location-based telemetry reporting policy. The mobile node sends, based on the comparison, the telemetry data via the wireless network.

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller assigns the access points to access point groups. The controller generates communication schedules for the access points such that each access point in an access point group is on a common channel and only one of neighboring directional transmitters of access points in that group is able to transmit at any given time. The controller sends the communication schedules to the access points forming the overhead mesh of access points in the area.

Abstract: In one embodiment, a networking device receives packets of a traffic flow destined for a mobile system. The networking device sends a first flowlet of the traffic flow towards the mobile system via a first wireless access point. The networking device determines an idle time between the first flowlet and a second flowlet of the traffic flow. The networking device sends, based on the idle time, the second flowlet towards the mobile system via a second wireless access point.

Abstract: Embodiments herein describe using transmission codes for ambient power stations (AMP STAs) so multiple AMP STAs can transmit in parallel to a Wi-Fi access point (AP). In order for the AMP STAs to transmit in parallel, the STAs use different codes. In one embodiment, the AMP STAs can use random timers to determine when they transmit and select a code to use during transmission. Before the timer expires, the AMP STAs can listen to see whether other AMP STAs are using the same code (e.g., a collision), and if so, select a different code. However, some AMP STAs may not have the ability to detect a collision. In that case, the AP can determine collisions for the AMP STAs and instruct the AMP STAs to select different codes.

Abstract: Techniques for coordinating traffic and performing preemption in multi-link operations are provided. At least a first portion of a first element of data is transmitted by the first network device via a first link. A second element of data is identified by the first network device. The transmission of the first element of data is interrupted by the first network device to transmit the second element of data via the first link. A remaining portion of the first element of data is transmitted by the first network device via a second link.

Abstract: Aspects described herein include a method of automated grouping of client devices for a user-defined network (UDN). The method includes receiving, from a first client device, an authentication request to join an access provider network. The authentication request includes a unique identifier of the first client device. The method also includes transmitting the unique identifier to a UDN cloud and receiving a first list from the UDN cloud. The first list indicates that the UDN is associated with the unique identifier. The method further includes joining the first client device with a second client device present on the access provider network based on a second list from the UDN cloud. The second list indicates that the UDN is associated with the second device.
