    摘要: A method for delivering packets in a wireless communications system includes determining a cause of loss for a previously transmitted packet based on a packet acknowledgement corresponding to the previously transmitted packet, the packet acknowledgement including at least one of a wireless loss indicator and a congestion warning indicator for the wireless communications system. The method also includes adjusting a transmission parameter in a packet transmission protocol according to the cause of loss, and retransmitting the previously transmitted packet.

    摘要: Techniques for transferring data among nodes on a network are disclosed. Some example methods include a downloader-initiated random linear network coding algorithm. A downloading node may be aware of the chunks of original data held by neighboring nodes, and the downloading node can request linear combinations of chunks from the neighboring nodes that are linearly independent of any linear combinations of chunks already held by the downloading node.

    摘要: Technologies are presented for power optimization of datacenter networks in a hierarchical perspective. In some examples, a two-level power optimization model may be established to reduce the power consumption of datacenter networks by switching off network switches and links while still guaranteeing full connectivity and maximum link utilization. The model may be implemented by solving a capacitated constraint multi-commodity flow (CMCF) problem employing simple heuristic techniques. A power status of network switches may be determined according to a network traffic matrix and the CMCF optimization determined at core-level and at pod-level. A complementary process to provision whole network connectivity and to meet quality of service (QoS) goals may also be performed.

    摘要: Techniques for managing resources in a point-to-multipoint (P2MP) network are disclosed. In some examples, a root station is adapted to transmit and receive network packets and leaf stations are adapted to transmit and receive the network packets from the root station. An electrical control system can be adapted to adjust a control error toward a zero value and adjust an output toward a steady state. The electrical control system may include feedback to control the root station based, at least in part, on the output of the electrical control system.

    摘要: A low rate DoS attack detection algorithm is used, which relies on a characteristic of the low rate DoS attack in introducing high rate traffic for short periods, and then uses a proactive test based differentiation technique to filter the attack packets. The proactive test defends against DDoS attacks and low rate DoS attacks which tend to ignore the normal operation of network protocols, but it also differentiates legitimate traffic from low rate DoS attack traffic instigated by botnets. It leverages on the conformity of legitimate flows, which obey the network protocols. It also differentiates legitimate connections by checking their responses to the proactive tests which include puzzles for distinguishing botnets from human users.

    摘要: Technologies are generally described for an enhanced Quantized Congestion Notification (QCN) congestion control approach, referred to as Fair QCN (FQCN) for enhancing fairness of multiple flows sharing link capacity in a high bandwidth, low latency data center network. QCN messages may be fed back to flow sources (e.g., servers) which send packets with a sending rate over their share of the bottleneck link capacity. By enabling the flow sources to regulate their data traffic based on the QCN messages from a congestion control component, the queue length at the bottleneck link may converge to an equilibrium queue length rapidly and TCP throughput performance may be enhanced substantially in a TCP incast circumstance.
