Congestion Avoiding Patents (Class 709/235)
  • Patent number: 10129153
    Abstract: A smart NIC (Network Interface Card) is provided with features to enable the smart NIC to operate as an in-line NIC between a host's NIC and a network. The smart NIC provides pass-through transmission of network flows for the host. Packets sent to and from the host pass through the smart NIC. As a pass-through point, the smart NIC is able to accelerate the performance of the pass-through network flows by analyzing packets, inserting packets, dropping packets, inserting or recognizing congestion information, and so forth. In addition, the smart NIC provides a lightweight transport protocol (LTP) module that enables it to establish connections with other smart NICs. The LTP connections allow the smart NICs to exchange data without passing network traffic through their respective hosts.

  • Patent number: 10069903
    Abstract: A distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes according to a per-flow hashed multipath routing technique. For a given packet flow, the LB nodes randomly select a server node as a target for the packet flow from among multiple server nodes and send a connection request to the server node. A load balancer module on the server node makes the decision on whether to accept or reject the connection based on one or more metrics indicating a respective server's current load. If the module accepts the connection request, a connection is established between the server and the client. Otherwise, the load balancer nodes may select another server node and try again. The connections established between clients and servers pass through the load balancer nodes, but are not terminated at the load balancer nodes.

  • Patent number: 9992786
    Abstract: Leveraging multiple network interfaces, such as Wi-Fi and cellular, on mobile devices can improve user experience for various applications. Deadline-aware MPTCP scheduling can complement existing MPTCP scheduler. The deadline-aware MPTCP scheduler can dynamically select transmission paths to minimize cellular usage while satisfying data transfer deadlines. The deadline-aware MPTCP scheduler can also address several challenges, such as determining the appropriate traffic pattern over cellular paths, designing proper APIs between MPTCP and applications, and making the scheduler functionality robust and lightweight.

  • Patent number: 9930091
    Abstract: Embodiments provide quality of service for media content delivery over capacity-constrained communications links to user devices by exploiting usage models and path awareness. For example, one or more uncongested beams can be identified as preceding one or more congested beams (e.g., by computing a congestion map) along a predicted transport path of a user device moving through a multi-beam satellite communications system. A prediction can be made as to one or more future requests that are likely to be made by the user device for pre-positionable types of media content, and that are likely to be serviced by one of the subsequent congested beams. When such a request for pre-positionable media content is predicted, embodiments can schedule transmission of at least a portion of the media content over one or more of the preceding uncongested beams for storage local to the user device, thereby pre-positioning the content at the client prior to reaching the congested beam.

  • Patent number: 9342339
    Abstract: One embodiment of the present invention provides a system that facilitates congestion management in a Fibre Channel (FC) network. During operation, the system determines a threshold data rate on an outgoing link coupled to an FC switch. The system further determines the number of sources that send data to the outgoing link and an aggregate arrival rate of data for the outgoing link. Next, the system determines an injection data rate for a respective source based on the threshold data rate on the outgoing link, the number of sources transmitting data to the outgoing link, and the aggregate arrival data rate for the outgoing link. Subsequently, the system communicates the injection data rate to the source, thereby allowing the source to throttle its data injection in the FC network to prevent network congestion.

  • Patent number: 9344368
    Abstract: Downstream path congestion is measured in respect of a node via which a plurality of data units are traversing an end-to-end path from a sender to a receiver. Each data unit has a first indication settable in dependence on information from the receiver to each of at least two states whereby to indicate different levels of congestion experienced on the end-to-end path by data units previously received by the receiver, and a second indication settable to an initial state and to at least one updated state indicative of congestion experienced by data units on their path from the sender to said node. A plurality of data units are received at the node, and the downstream path congestion measure is determined in dependence on an inflation factor itself dependent on the proportion of a set of the data units whose second indication on receipt at the node is in the initial state.

  • Patent number: 9237034
    Abstract: In a networked multi computer environment, with redundant links, network interface cards (NICs) are commonly duplicated and teamed to provide a recovery mechanism when network components fail. Embodiments of the present inventions avoid teaming of pairs of NICs and provide a computing host with redundant network connections for the computing host through a switch that is transparent to the computing host. The computing host itself; that is, its hardware and software, is relieved of the duty of network access redundancy and returned to the simple, simplex networking operating mode. The switch replaces a potentially large number of NICs and the need for computing host network access redundancy management which leads to hardware and software cost reductions and increases the robustness and reliability of the system through redundant network access.

  • Patent number: 9219691
    Abstract: Embodiments relate to proactively probing the packet queues of elements in a physical or virtual network to predict and prevent the occurrence of congestion points. An aspect includes receiving a first feedback request at a central controller connected to a plurality of switches in a network. The first feedback request includes a request to periodically probe a status of queues of switches in the network. A second feedback request is then transmitted to one or all the switches in a path leading to a designated destination. Responses to the second feedback request are received at the central controller from a designated proxy switch, which aggregated the responses into a single data packet. Accordingly, the responses extracted from the single data packet at the central controller are used to preventing future congestion points.
