Abstract: Techniques are described for managing devices (120, 122, 124, 126, 128, 130, 132, 140, 142, 144, 146, 148, 150, 152) using multiple virtual personal area networks VPANs (110, 112). A border router (102) receives a first request to join a network (100) from a first device. The first device is assigned to a first virtual personal area network VPAN (110), which has an associated first group temporal key GTK. The first GTK is distributed to the first virtual device. The border router (102) also receives a second request to join the network (110) from a second device. The second device is assigned to a second VPAN (112), which has an associated second GTK. The second GTK is distributed to the second virtual device.

Abstract: Service cognizant radio role assignments may be provided. A computing device may receive a beacon message associated with a tag. Then, based on information derived from the beacon message, an optimum radio in a network may be determined to monitor the tag. The optimum radio may be associated with an Access Point (AP) comprising one of a plurality of APs in the network. The optimum radio associated with the AP in the network may then be provisioned to monitor the tag.

Abstract: This technology allows time synchronization in passive optical networks ("PON"). A first Ethernet device timestamps and transmits a packet to a second Ethernet device via the PON. The first Ethernet device transmits the packet to a small form-factor pluggable ("SEP") device within the PON and connected to the first Ethernet device. The SEP device determines a transmission time to a second SEP device and modifies a correction field ("CF") of the packet by subtracting an ingress time and the transmission time from the CF. The packet is transmitted to the second SFP device, which modifies the CF by the addition of an egress time. The modified CF value represents the real-time transmission delay inclined in the SFP devices. The packet is transmitted to a second Ethernet device to synchronize a clock using the timestamp and the CF value in accordance with the PTP/IEEE-1588 standard.

Abstract: A method includes instructing, by a WiFi access node, a first device to communicate using an uplink frequency band with a first uplink power. The method also includes instructing, by the WiFi access node, a second device to communicate using the uplink frequency band with a second uplink power different from the first uplink power.

Abstract: Techniques for a context-aware secure access service edge (SASE) engine for generating security profile(s) associated with endpoint device(s) accessing the network and using the security profile(s) to evaluate a traffic flow from the endpoint device(s). The SASE engine may execute on an edge device of a computing resource network and may be configured to maintain a security profile database including an endpoint security profile mapping. Endpoint device(s) accessing the network may share endpoint, application, and/or user specific information with the SASE engine so that the SASE engine may generate a security profile specific to the endpoint, application, and/or user. Additionally, an enterprise network, associated with endpoint device(s) accessing the network, may provide default SASE security profile templates to the SASE engine. Further, a feedback loop may be established between the SASE engine and the endpoint device(s), enabling the SASE engine with the ability to autonomously and dynamically update security profiles.

Abstract: Techniques for temperature control for multiple dies in an element. A temperature of a first die is measured, in an element comprising the first die and a second die. The second die includes at least a portion of a controller. The temperature of the first die is changed by adjusting activity, from the second die to the first die, based on a target temperature for the first die and the measured temperature for the first die.

Abstract: In one embodiment, Segment Routing Internet Protocol Version 6 (SRv6) micro segments ("uSIDs") are included in destination addresses, and possibly in other Segment Identifiers ("SIDs"), of packets transported through a network, and invoking corresponding network behavior, including, but not limited to, realization of corresponding network slices. In one embodiment, network nodes are configured to perform differential network slice realization functionality based on values slice-representative value(s) provided by global and/or local uSIDs of packets. This configuration may be defined by a controller in the network and/or routing protocol advertisements. Responsive to a received packet, a network node identifies and performs the corresponding network slice realization functionality based on slice-representative value(s) provided by one or more global and/or local uSIDs of the destination address of the received packet. Various encodings within an IPv6 Destination Address of the encapsulating packet are disclosed.

Abstract: Techniques for creating consent contracts for devices that indicate whether the devices consent to receiving network-based communications from other devices. Further, the techniques include enforcing the consent contracts such that network-based communications are either allowed or disallowed in the network- communications layer prior to the network communications reaching the devices. Rather than simply allowing a device to communicate with any other device over a network, the techniques described herein include building in consent for network-based communications where the consent is consulted at one or more points in a communication process to make informed decisions about network-based traffic.

Abstract: End-face coupling structures within an electrical backend are provided via photonic integrated circuit (PIC), comprising: a first plurality of spacer layers; a second plurality of etch-stop layers, wherein each etch-stop layer of the second plurality of etch-stop layers is located between two spacer layers of the first plurality of spacer layers; and an optical coupler comprising a plurality of waveguides arranged as a waveguide array configured to receive an optical signal in a direction of travel, wherein each waveguide of the plurality of waveguides is located at a layer interface defined between an etch-stop layer and a spacer layer. Portions of the PIC can be formed by depositing layers of spacer and etch-stop materials in which cavities are formed to define the waveguides when the waveguide material is deposited or interconnects when a metal is deposited therein.

Abstract: Techniques for utilizing a communication system that provides access to a representation of a virtual environment to participants. The communication system may establish connections between personal communication bridge(s) associated with participant(s) interacting within a virtual proximity radius of one another's virtual indicator in the virtual environment. The communication system may cause conversation data to be sent each personal communication bridge associated with a participant that is within the virtual proximity radius of the sender, and cause conversation data to be received via the personal communication bridge of a participant that is within the virtual proximity radius of the sender. The communication system may also analyze data associated with the participant profile(s) and transcribed conversation data from the communication bridges(s) to recommend potential conversations of interest to participant(s).
