摘要： Various implementations disclosed herein enable controlling access to networks. In various implementations, a method of controlling access to a network is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes obtaining an indication that a mobile device having access to a first network utilizing a first radio access technology (RAT) has requested access to a second network utilizing a second RAT. In some implementations, the method includes determining whether the access to the first network satisfies an authentication criterion associated with the second network. In some implementations, the method includes granting the mobile device access to the second network in response to determining that the access to the first network satisfies the authentication criterion associated with the second network. In some implementations, accessing the second network via the authentication criterion satisfies an operating threshold associated with the mobile device.

摘要： A method of configuring network devices. The method may include, with a network orchestrator, measuring at least one characteristic of a quality of a link between a network device and the network orchestrator during a first measurement window, categorizing the link into a connection type based on the at least one characteristic, and tuning a configuration of the network device based at least in part on the connection type identified by the network orchestrator.

摘要： 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.

摘要： 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.

摘要： The present technology pertains to a system that routes application flows. The system can receive an application flow from a device by an active threat detection agent; analyze the application flow for user context, device context, and application context; classify the application flow based on the analysis of the application flow; and direct the application flow according to the classification of the application flow and an application access policy.

摘要： Methods and systems to estimate encrypted multi-path TCP (MPTCP) network traffic include restricting traffic in a first direction (e.g., uplink) to a single path, and estimating traffic of multiple subflows of a second direction (e.g., downlink) based on traffic over the single path of the first direction. The estimating may be based on, without limitation, acknowledgment information of the single path, a sequence of acknowledgment numbers of the single path, an unencrypted initial packet sent over the single path as part of a secure tunnel setup procedure, TCP header information of the unencrypted initial packet (e.g., sequence number, acknowledgment packet, and/or acknowledgment packet length), and/or metadata of packets of the single path (e.g., regarding cryptographic algorithms, Diffie-Helman groups, and/or certificate related data).

摘要： Techniques for handling requests from a remote device are disclosed. A server receives a first unsolicited activation request from a first device of a plurality of devices. A probabilistic hash filter, associated with a data set, is queried using a first identifier associated with the first device. In response, a first result is received from the probabilistic hash filter indicating that the first device is not ready for activation. In response to receiving the first result, a back-off indication is transmitted to the first device.

摘要： The disclosed technology relates to systems and methods for automatically scaling down network resources, such as servers or gateway instances, based on predetermined thresholds. A system is configured to detect a reduction in one or more network metrics related to a first server, and instruct the first server to issue a rekey request to a plurality of devices connected to the first server. The system is further configured to instruct a load balancer to route to at least one other server responses from the plurality of devices to the rekey request, and determine a number of connections remaining between the first server and the plurality of devices. The system may be further configured to instruct the load balancer to terminate the first server based on the detected number of connections remaining between the first server and the plurality of devices.

摘要： 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.

摘要： Various implementations disclosed herein enable identifying anomalies in a network. For example, in various implementations, a method of identifying anomalies in a network is performed by a network node. In various implementations, the network node includes one or more processors, and a non-transitory memory. In various implementations, the method includes generating a characteristic indicator that characterizes a device type based on communications associated with a first device of the device type. In various implementations, the method includes determining, based on communications associated with the first device, a performance indicator that indicates a performance of the first device. In various implementations, the method includes synthesizing an anomaly indicator as a function of the performance indicator in relation to the characteristic indicator.
