Methods, systems and apparatuses for scheduling a plurality of Virtual Links (VLs) in a Time-Triggered Ethernet (TTE) network by a network scheduling and configuration tool (NST) by establishing a collection of bins that corresponds to the smallest harmonic period allowing full network traversal of a time-triggered traffic packet in the network for determining available bin sets for sending the VL data by the NST; processing by a scheduling algorithm the VLs to be sent in accordance with a strict order comprising scheduling all the highest rate VLs prior to scheduling lower rate VLs; and scheduling reservations for the VLs in bins by tracking the available time available in each bin and optionally spreading the VL data across available bin sets by sorting a list of available bins by ascending bin utilization and by specifying a left-to-right or right-to-left sort order when searching for available bins based on a position in the timeline between the transmitter and receiver end stations.

In one embodiment, a system comprises an interface to receive a plurality of packets; and a plurality of processor units to execute a plurality of transmission sub-interfaces, each transmission sub-interface to perform hierarchical quality of service (HQoS) scheduling on a distinct subset of the plurality of packets, wherein each transmission sub-interface is to schedule its subset of the plurality of packets for transmission by a network interface controller by assigning the packets of the subset to a plurality of transmission queues that each correspond to a distinct traffic class.

Technologies for balancing throughput across input ports include a network switch. The network switch is to generate, for an arbiter unit in a first stage of a hierarchy of stages of arbiter units, turn data indicative of a set of turns in which to transfer packet data from devices connected to input ports of the arbiter unit. The network switch is also to transfer, with the arbiter unit, the packet data from the devices in the set of turns. Additionally, the network switch is to determine weight data indicative of the number of turns represented in the set and provide the weight data from the arbiter unit in the first stage to another arbiter unit in a subsequent stage to cause the arbiter unit in the subsequent stage to allocate a number of turns for the transfer of the packet data from the arbiter unit in the first stage.

Approaches are described for release-time-driven (RTD) prioritization of on-board content scheduling and delivery to in-transit transport craft via communications systems. In context of a constrained network, content is scheduled to be delivered to those in-transit on-board media servers in a manner driven by respective release times and other prioritization factors associated with the updated content. Each content is associated with a RTD priority profile that can define a release time, a release priority, and a profile plot for the content. The RTD priority profiles can be used to compute priority surfaces that define priority scores over a multidimensional space for a particular time. A subset of the content can be selected for delivery based on the priority surfaces, and can be scheduled for delivery according to network capacity determinations.

The present disclosure relates to an SDN-based VPN traffic scheduling method and scheduling system. The method includes: configuring an SDN switching device to implement establishment of a communication link between a CE device and a PE device; performing VPN configuration on a controller; distributing, by the controller, a corresponding flow table to the SDN switching device, the flow table being used to translate a repeated address within a VPN to a non-conflict space address to distinguish different VPN traffic; configuring, by the controller, different traffic scheduling paths for the different VPN traffic according to a preset traffic scheduling strategy; and distributing, by the controller, the traffic scheduling paths to the PE device.

Methods and devices for determining settings for a virtual machine may include partitioning a physical network into a plurality of traffic classes. The methods and devices may include determining at least one virtual enhanced transmission selection (ETS) setting for one or more virtual machines, wherein the virtual ETS setting includes at least one virtual traffic class that corresponds to one of the plurality of traffic classes. The methods and devices may include transmitting a notification to the one or more virtual machines identifying the virtual ETS setting.

Device Assisted Services (DAS) for protecting network capacity is provided. In some embodiments, DAS for protecting network capacity includes monitoring a network service usage activity of the communications device in network communication; classifying the network service usage activity for differential network access control for protecting network capacity; and associating the network service usage activity with a network service usage control policy based on a classification of the network service usage activity to facilitate differential network access control for protecting network capacity.

Technologies for scheduling time-sensitive cyclical network traffic in real-time include an internet-of-things (IoT) device that includes at least one sensor for collecting sensor data. The IoT device is configured to store the collected sensor data in a data buffer, allocate a packet descriptor for the sensor data, and populate the allocated packet descriptor with a cyclic data port pointer indicative of a location of the data buffer. The IoT device is additionally configured to queue the packet descriptor into a media access control (MAC) unit transmit direct memory access (DMA) of the IoT device, fetch the sensor data, and packetize the fetched data to form a network packet. Further, the IoT device is configured to transmit the network packet to a target computing device based on a launch time, update the launch time, and requeue the packet descriptor into the MAC unit transmit DMA. Other embodiments are described herein.

Systems and methods are disclosed for enhancing network performance by using modified traffic control (e.g., rate limiting and/or scheduling) techniques to control a rate of packet (e.g., data packet) traffic to a queue scheduled by a Quality of Service (QoS) engine for reading and transmission. In particular, the QoS engine schedules packets using estimated packet sizes before an actual packet size is known by a direct memory access (DMA) engine coupled to the QoS engine. The QoS engine subsequently compensates for discrepancies between the estimated packet sizes and actual packet sizes (e.g., when the DMA engine has received an actual packet size of the scheduled packet). Using these modified traffic control techniques that leverage estimating packet sizes may reduce and/or eliminate latency introduced due to determining actual packet sizes.
