Abstract: Systems and methods are provided for transmitting buffer state report poll (BSRP) triggers from a WLAN device with a BSRP frequency that is based on an amount of pending data at the UL buffer of each station associated to the WLAN device. The BSRP frequency can further be based on a priority of the pending data at the UL buffer. The amount of pending data at the UL buffer can be compared to a threshold, the value of which can depend on the priority of the pending data, and the BSRP frequency can be based on the comparison.

Abstract: The invention includes, in part, storing a seed image having instructions to communicate with devices of a predetermined device type, but not instructions to provision a network device to be fully operational in a network. A processor boots a network device in the network for a first time, detects if another network device exists in the network, and downloads a full version of a product image from the other network device. The full version of the product image uniquely corresponds to network devices deployed in the network that include at least one device of the predetermined device type, replaces the seed image with the full version of the product image, and provisions the network device to a particular device type of the network.

Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.

Abstract: A memory tile, in a local memory, may be considered to be a unit of memory structure that carries multiple memory elements, wherein each memory element is a one-dimensional memory structure. Multiple memory tiles make up a memory segment. By structuring the memory tiles, and a mapping matrix to the memory tiles, within a memory segment, non-blocking, concurrent write and read accesses to the local memory for multiple requestors may be achieved with relatively high throughput. The accesses may be either row-major or column-major for a two-dimensional memory array.

Abstract: Data mining large-scale corpora of scholarly publications, such as the full biomedical literature, which may consist of tens of millions of papers spanning decades of research. The present disclosure provides a Distributed Accelerated Semiring All-Pairs Shortest Path (DSNAPSHOT) algorithm for computing shortest paths of a knowledge graph using distributed-memory parallel computers accelerated by GPUs. DSNAPSHOT implementations can analyze connected input graphs with millions of vertices using a large number graphics processing units (e.g., the 24,576 GPUs of the Oak Ridge National Laboratory's Summit supercomputer system). DSNAPSHOT provides sustained performance of about 136*1015 floating-point operations per second (136 petaflop/s) at a parallel efficiency of about 90% under weak scaling and, in absolute speed, 70% of the performance given our computation (in the single-precision tropical semiring or “min-plus” algebra).

In an example, a request to authenticate an IoT device coupled to a network device is sent to an authentication server. The request includes a Media Access Control (MAC) address of the IoT device. A response indicative of successful authentication of the IoT device based on the MAC address is received from the authentication server. The response includes a first attribute indicative of a network address of a remote server to connect with the IoT device. A firewall role for the IoT device is generated based on a combination of an Internet Protocol (IP) address of the IoT device and the first attribute. The IoT device is associated with the firewall role.
