Abstract: In one example, a wireless Access Point (AP) is configured to provide network connectivity between a User Equipment (UE) and a private wireless network. The wireless AP obtains, from the private wireless network, an indication that the UE is unregistered with the private wireless network. In response to the indication that the UE is unregistered with the private wireless network, the wireless AP provides, to the private wireless network, an indication to initiate an emergency attach procedure with respect to the UE. In response to the indication to initiate the emergency attach procedure, the wireless AP obtains, from the private wireless network, an indication that the UE is authorized to access the private wireless network. In response to the indication that the UE is authorized to access the private wireless network, the wireless AP provides guest access to the private wireless network on behalf of the UE.

Abstract: Techniques for dynamic prioritization of network session are provided. A first packet belonging to a first session is received at a data plane of a network. Upon determining that the first packet is part of a first roam event, a first bloom filter bank is searched to determine a priority associated with the first session, where the priority is based at least in part on a historical latency experienced during the first roam event. A first queue of a plurality of queues is selected based on the determined priority, and the first packet is added to the first queue, where packets in the plurality of queues are transmitted to a control plane of the network based on a respective priority assigned to each of the plurality of queues.

Abstract: Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

Abstract: Systems and methods provide for Selective Tracking of Acknowledgments (STACKing) to improve buffer utilization and traffic shaping for one or more network devices. A network device can identify a first flow that corresponds to a predetermined traffic class and a predetermined congestion state. The device can determine a current window size and congestion threshold of the first flow. In response to a determination to selectively track a portion of acknowledgments of the first flow, the device can track, in main memory, information of a first portion of acknowledgments of the first flow. The device can exclude, from one or more buffers, a second portion of acknowledgments of the first flow. The device can re-generate and transmit segments corresponding to the second portion of acknowledgments at a target transmission rate based on traffic shaping policies for the predetermined traffic class and congestion state.

Abstract: Systems, methods, and computer-readable storage media are provided for parallel initiating of devices in a system. The method includes generating an affinity table that stores option ROM execution data including first data associated with a first device and second data associated with a second device and triggering, based on the affinity table, a first initialization of the first device and executing a first option ROM code during a pre-boot phase and triggering, based on the affinity table, a second initialization of the second device and executing a second option ROM code during the pre-boot phase. Triggering the first initialization of the first device and triggering the second initialization of the second device during the pre-boot phase is performed such that at least a part of the first initialization of the first device and at least part of the second initialization of the second device are executed in parallel.
