Abstract: Methods, systems, and computer programs are directed to the implementation of configurable hierarchical schedulers with multiple levels, where each level may use one of several types of queueing mechanisms. A configurable, hierarchical scheduler is designed to handle large scale processing of requests (e.g., transmitting outgoing messages). The hierarchical scheduler distributes the loads to different queues handling different types of messages (e.g., by user ID, by Internet Address (IP), by schedule). The different layers of the hierarchical scheduler are configurable to queue and schedule traffic based on many factors, such as IP address, handling reputation, available downstream bandwidth, fairness, concurrency rates to handle multiple constraints, scheduling per client, time of delivery constrains, rate limits per user, domain scheduling per user, concurrency throttling per outbound channel, and sharing global rate limits across service processors.

Abstract: Artificial intelligence is an increasingly important sector of the computer industry. However, artificial intelligence is an extremely computationally intensive field such that performing artificial intelligence calculations can be expensive, time consuming, and energy consuming. Fortunately, many of the calculations required for artificial intelligence applications can be performed in parallel such that specialized linear algebra matrix processors can greatly increase computational performance.

Without proper coordination, linear algebra matrix processors may end up idle or spending large amounts of time moving data around. Thus, this document discloses methods for efficiently scheduling linear algebra matrix processors.

Abstract: Solutions are disclosed that provide for proxy-call session control function (P-CSCF) awareness of access point name (APN) or data network name (DNN). This permits the P-CSCF to enforce policies regarding use of internet protocol (IP) multimedia subsystem (IMS) resources, such as certain voice codecs (e.g., enhanced voice services, EVS) that use larger amounts of bandwidth, based on the APN/DNN assigned to a user equipment (UE).

In some examples, a packet gateway (PGW) or session management function (SMF) inserts APN/DNN information into a session initiation protocol (SIP) message going to the P-CSCF. In some examples, the P-CSCF retrieves APN/DNN information from a policy and charging rules function (PCRF) or a policy control function (PCF).

Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not.

If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for managing uplink access in a wireless local area network. A station (STA) may inform an access point (AP) of uplink quality of service (QoS) parameters for a traffic flow from the STA. The AP may control uplink resources to satisfy the QoS parameters. For example, the AP may select from among different access modes (including a single user (SU) access mode, an uplink multi-user (UL-MU) scheduled access mode, a multi-user enhanced distributed controlled access (MU EDCA) access mode, or a low latency (LL) access mode). The AP may cause the STA to use a SU access mode or the LL access mode if the UL-MU scheduled access mode and the MU EDCA access mode are not sufficient to satisfy the uplink QoS parameters for the traffic flow.

Abstract: A reduced-complexity optical packet switch which can provide a deterministic guaranteed rate of service to individual traffic flows is described. The switch contains N input ports, M output ports and N*M Virtual Output Queues (VOQs). Packets are associated with a flow f, which arrive an input port and depart on an output port, according to a predetermined routing for the flow. These packets are buffered in a VOQ. The switch can be configured to store several deterministic periodic schedules, which can be managed by an SDN control-plane. A scheduling frame is defined as a set of F consecutive time-slots, where data can be transmitted over connections between input ports and output ports in each time-slot. Each input port can be assigned a first deterministic periodic transmission schedule, which determines which VOQ is selected to transmit, for every time-slot in the scheduling frame.

Abstract: A business method associates provisioning costs with a usage history indicative of user computing demand, and coalesces the cost data to identify an appropriate provisioning level balancing the provisioning cost and the usage demand cost. Conventional computing environments suffer from the shortcoming of being prone to overprovisioning or underprovisioning a user. Such misprovisioning is inefficient because it denotes underutilized computing resources or ineffective and/or disgruntled users. Costs increase either due to the excessive hardware bestowed on the overprovisioned user, or in support costs addressing the underprovisioned user. Configurations herein substantially overcome such shortcomings by defining a policy indicative of overprovisioning and underprovisioning indicators (misprovisioning flags), and defining rules to specify a triggering event indicating the need to reassess the provisioning of a user.

Abstract: The disclosure herein describes performing resynchronization (“resync”) jobs in a distributed storage system based on a parallelism policy. A resync job is obtained from a queue and input/output (I/O) resources that will be used during execution of the resync job are identified. Available bandwidth slots of each I/O resource of the identified I/O resources are determined. The parallelism policy is applied to the identified I/O resources and the available bandwidth slots. Based on the application of the parallelism policy, a bottleneck resource of the I/O resources is determined and a parallel I/O value is calculated based on the available bandwidth slots of the bottleneck resource, wherein the parallel I/O value indicates a quantity of I/O tasks that can be performed in parallel. The resync job is executed using the I/O resources, the execution of the resync job including performance of I/O tasks in parallel based on the parallel I/O value.

Abstract: A method of managing a network for delivering content to a client device, where content segments are delivered over multicast to a proxy. The received segments are stored at the proxy, before delivery of those segments is made from the proxy to the client device over unicast. Whilst the proxy receives further segments over multicast, it probes the network by making unicast requests for data (dummy data or additional content segments), and receiving those segments over unicast from the content server. The multicast rate reception rate and the unicast (probe) rate are measured and a maximum network throughput is calculated as the sum of these two rates. Subsequent segments are then delivered from the proxy to the client device at the calculated maximum network throughput rate, or at some rate dependent thereon.

In some examples, ingress leaf nodes send data through the fabric that indicate egress nodes for the communication paths. Intermediate nodes along may receive the data from the leaf nodes to identify communication paths, and the notify only affected nodes upon detecting a failure in the network.
