  • Publication number: 20220217098
    Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution for streaming communication between devices. In this solution, a memory of a first device comprising a ring buffer is allocated to be dedicated for storing a data stream of an application to be transmitted to a second electronic device. The application of the first device writes data to be transmitted into the ring buffer, to form a portion of the first data stream, and a write pointer of the ring buffer is thus updated. A portion of data is read based on a source memory address from the ring buffer via the interface device. The interface device also transmits the data portion to a second device. The read data portion is stored in a dedicated ring buffer of the memory. In accordance with the solution, an efficient streaming communication interface is provided between devices.

  • Publication number: 20200396233
    Abstract: The present concepts relate to identifying entities based on their behavior using machine learning models. Where an entity may be a bot or a human, the entity's requests sent to a website are used to generate a graph. The graph may be used to create an image, such that the image reflects the entity's browsing behavior. A machine learning model, which has been trained using a first training set of images that correspond to bots and a second training set of images that correspond to humans, can determine whether the entity is a bot or a human by performing an image classification.

  • Patent number: 9590922
    Abstract: This application describes routing packets from a source server to a plurality of ports of a switch. The switch is programmed by the control server and is used to direct incoming data packets to one or more ports of the switch in a manner that reduces congestion of incoming data packets to a destination server. Further, the control server queries congestion information from the switch, and then sends congestion notification back to the source server to either increase or decrease the amount of data being sent to the destination server.

  • Patent number: 9276866
    Abstract: A system, method or computer readable medium to provide efficient congestion notification is described herein. In various embodiments, a packet is received at an intermediate node of one or more data center networks. A current queue length at the intermediate node is determined. A threshold value for the current queue length is tuned by dynamically computing an upper bound and a lower bound based at least in part on the network. The packet is marked to indicate possible congestion in the one or more data center networks when the current queue length exceeds the threshold value. In some embodiments, the packet is marked when it is being de-queued. In a further embodiment, Flexible Initial Packet Size (FIPS) may be utilized to improve the efficiency of the tuning.

  • Patent number: 8504734
    Abstract: Hybrid tree/mesh overlays for data delivery involve using a tree overlay network and a mesh overlay network to delivery a data stream via a push mechanism and a pull mechanism, respectively. In an example embodiment, a network node enters a mesh overlay network and attaches to a tree overlay network. In operation, the network node receives data blocks of a data stream over the tree overlay network via a push mechanism. The network node ascertains if a data block is not received over the tree overlay network. If a data block is missing, the network node retrieves the missing data block over the mesh overlay network via a pull mechanism. In another example embodiment, the tree overlay network includes a subset of nodes forming a tree-based backbone. Network nodes that are identified as being stable may join the backbone and provide the data stream to other nodes.

  • Patent number: 8184656
    Abstract: A dual mode communication device utilizes a control channel to exploit diversity, history, and context in advance of establishing a broadband data exchange session on a broadband but shorter range wireless data channel, maximizing productive use of such a session. Appropriate diversity for the negotiated session further enhance data transfer, including path diversity, radio technology diversity (e.g., WiMax, Wi-Fi, ultra wideband, Bluetooth), antenna diversity (e.g., MIMO), modulation diversity (e.g., rate selection for 802.11, or symbol length selection to combat multi-path fading), and frequency diversity (e.g., 2.4 GHz versus 5 GHz). Historical information about channel characteristics optimize the selection of channel parameters with respect to the diversity choices. In addition, context information such as location and speed can be used to categorize the historical information that is collected to further optimize channel parameters.
