  • Patent number: 11979312
    Abstract: An end-to-end path can be set without providing a hierarchy in a control device of a multi-domain network. A path setting system (10) includes an orchestrator 200 and a control device (100). The orchestrator (200) generates path candidates corresponding to a line of domains through which paths that are candidates for a path pass and transmits the path candidates to control devices (100) of domains through which the path candidates pass to request setting of the path. The control device (100) acquires, from the control devices (100) of other domains through which path candidates pass, metrics of the path candidates in the domains, calculates total metrics, selects an optimum path, and sets the optimum path.

    Abstract: According to one or more embodiments of the disclosure, an asset inventory service executed by one or more devices receives telemetry data collected passively by a sensor application regarding a node in a network. The asset inventory service requests, after receiving the telemetry data, that the sensor application perform active discovery of nodes in the network. The asset inventory service receives active discovery data collected by the sensor application via active discovery of nodes in the network. The asset inventory service generates, based on the telemetry data and the active discovery data, an identity profile for the node.

  • Patent number: 11936613
    Abstract: The method for a virtual machine to use a port and loopback IP addresses allocation scheme for full-mesh communications with transparent transport layer security tunnels is presented. In an embodiment, the method comprises detecting, at a redirect agent implemented in a first machine, a packet that is sent from a client application executing on the first machine toward a server application executing on a second machine; and determining, by the redirect agent, whether a first redirect rule matches the packet. In response to determining that the first redirect rule matches the packet, the redirect agent applies the first redirect rule to the packet to translate the packet into a translated packet, and provides the translated packet to a client agent implemented in the first machine to cause the client agent to transmit the translated packet to a server agent implemented in the second machine.

    Abstract: A method includes receiving a plurality of files where each file represents an object. The method further combines selected files of the plurality of files into an aggregation file and stores the aggregation file on low-latency storage media, such as disk storage media. The method represents the aggregation file with a single inode that is stored on the low-latency storage media. The method migrates the aggregate file to high-latency storage media, such as tape storage media. By collecting files into larger aggregation files, the number of files archived is significantly reduced and the files archived are of larger size. The reduced number of files and increased size of the files improves archival and retrieval performance due to reduced metadata operation overhead.

  • Patent number: 11340637
    Abstract: The present invention is a fluid distribution system comprising connected conduits (e.g., lines) wherein fluid flows, such as pipes within a building. The lines may be configured to: (i) include multiple lines that connect at intersections (some of the intersections will be identified as nodes); and (ii) incorporate node units associated with line pressure loss simulation assemblies (“LLSAs”). Activities of a node unit incorporating a LLSA can result in alterations in fluid pressure, such as by a loop control process to reposition balancing valves or other valves of one or more LLSAs, and/or by alteration of the speed of the system pump. These activities adjust fluid pressure to cause the system to produce a balanced and high efficiency energy transfer (e.g., heating or cooling), and do not involve or require any identification or use of any specific, fixed or absolute pressure value.

  • Patent number: 11178694
    Abstract: A wireless communication circuit for operating over a wireless local area network (WLAN) in which real time application (RTA) traffic and non-RTA traffic coexist and are distinguished from one another. RTA queues are created to enqueue RTA packets while non-RTA packets are pushed into non-RTA queues. Management frames containing RTA session parameters and RTA queue setting information are exchanged between stations. Channel time is allocated to RTA queues for transmitting packets, during which non-RTA queues are not allowed to access the channel. Stations determine which RTA queues to enqueue an RTA packet into based on RTA queue classification information of its RTA session.

  • Patent number: 11076124
    Abstract: An HDMI source conversion device according to one aspect of the disclosure includes an HDMI interface, an IP interface, and a converter. The HDMI interface receives a first signal based on the HDMI communication protocol. The IP interface receives address information from a control device via a network based on the Internet protocol, the control device being connected to the network, and the address information indicating the address on the network of an HDMI sink conversion device that is a device different from the control device. The converter converts the first signal based on the HDMI communication protocol into a second signal based on the Internet protocol by adding at least the address information to the first signal received by the HDMI interface. The IP interface transmits the second signal to the HDMI sink conversion device via the network.

  • Patent number: 11063903
    Abstract: The method for a virtual machine to use a port and loopback IP addresses allocation scheme for full-mesh communications with transparent transport layer security tunnels is presented. In an embodiment, the method comprises detecting, at a redirect agent implemented in a first machine, a packet that is sent from a client application executing on the first machine toward a server application executing on a second machine; and determining, by the redirect agent, whether a first redirect rule matches the packet. In response to determining that the first redirect rule matches the packet, the redirect agent applies the first redirect rule to the packet to translate the packet into a translated packet, and provides the translated packet to a client agent implemented in the first machine to cause the client agent to transmit the translated packet to a server agent implemented in the second machine.

  • Patent number: 11032398
    Abstract: A system for providing a message-based protocol for multiplexing messages sent via a stream-based connection protocol is provided. A multiplexing system provides high-level sockets of the message-based protocol that interact with low-level sockets of a stream-based connection protocol. The multiplexing system executes in a privilege mode. To send a message, an application uses a high-level socket to provide a request to send the message using the multiplexing system. The multiplexing system selects an available low-level socket from a group of sockets and sends the message via that socket. The message is sent as an atomic operation. If, during the sending of the message, the application requests to send another message, the multiplexing system selects another available low-level socket of the group and sends the other message via the selected low-level socket.

  • Patent number: 10999169
    Abstract: This disclosure describes techniques for configuring and managing scalable global private networks associated with a service provider. Different input mechanisms, such as an API, a UI, or a CLI may be utilized to configure, and manage a global private network that spans across the cloud in different geographic locations and connects to different stand-alone networks. The user may proactively use the input mechanisms to configure and query different network resources to reactively configure settings for reacting to one or more events. The input mechanisms may also be utilized to define the network resources to be modeled within the global private network as well as connections within the global network. A user may configure events/metrics to be monitored, tasks/workflows to be performed, and the like. In some configurations, a network management service (NMS) may perform health monitoring and reachability monitoring to identify possible issues in the global network.
