Abstract: A first flowlet of a flow from a source network device to a destination network device is assigned to a first path of a plurality of paths between the source device and the destination device. The assignment of the first flowlet to the first path is made by a network connected device. A second flowlet is detected in response to an interruption in transmission of the flow due to congestion along the first path, wherein the interruption is longer in duration than a difference in a transmission time between the source network device and the destination network device along each of the plurality of paths. The second flowlet is assigned to a second path of the plurality of paths by the network connected device. According to some example embodiments, the second path is randomly selected from the plurality of paths.

Abstract: In one embodiment, an HTTP streaming session may be initiated at a client device in a network. The client device may have a buffer and may be configured to request and receive one or more data segments over HTTP from an HTTP server. A first data segment at a first data source rate may be requested and subsequently received. The first data segment may be stored in the buffer. A second data source rate may then be calculated based on a storage level in the buffer, and a second data segment at the second data source rate may be requested.

Abstract: A method in one embodiment includes intercepting a message in an on-board unit (OBU) of a vehicular network environment between a source and a receiver in the vehicular network environment, verifying the message is sent from the source, verifying the message is not altered, evaluating a set of source flow control policies associated with the source, and blocking the message if the set of source flow control policies indicate the message is not permitted. In specific embodiments, the message is not permitted if a level of access assigned to the source in the set of source flow control policies does not match a level of access tagged on the message. In further embodiments, the method includes evaluating a set of receiver flow control policies associated with the receiver, and blocking the message if the set of receiver flow control policies indicates the message is not permitted.

Abstract: The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

Abstract: In one embodiment, a method includes measuring a rate of traffic received at a leaf node, marking a plurality of packets in the flow as protected at the leaf node to match the rate of traffic with a configured rate of traffic for the flow at the leaf node, and dropping a plurality of non-protected packets at the leaf node when a queue at the leaf node is congested. A minimum bandwidth is provided for the flow based on the configured rate of traffic at the leaf node. The leaf node comprises an ingress node or an egress node connected to a fabric. An apparatus is also disclosed herein.

Abstract: In one implementation, an input queue switch provides latency fairness across multiple input ports and multiple output ports. In one embodiment, each input port maintains a virtual output queue for each associate output port. The virtual output queues across multiple inputs are aggregated for each specific output port. The sum of the lengths of the virtual output queues is compared to a threshold, and based on the comparison, feedback may be generated to control the operation of the input port for subsequent packets. The feedback may instruct the input port to stop buffering or drop packets destined for the output port with the sum of the lengths of the virtual output queues associated to the specific output port that exceeds the threshold. In another embodiment, each packet has an arrival timestamp, and a virtual output queue having the oldest timestamp is selected first to dequeue.
