  • Patent number: 10652135
    Abstract: In one embodiment, a multicast listener device floods a path lookup request to search for a multicast tree, and may then receive path lookup responses from candidate nodes on the multicast tree, where each of the path lookup responses indicates a unicast routing cost from a respective candidate node to the multicast listener device, and where each of the candidate nodes is configured to suppress a path lookup response if a total path latency from a source of the multicast tree to the multicast listener device via that respective candidate node is greater than a maximum allowable path latency. The multicast listener device may then select a particular candidate node as a join point for the multicast tree based on the particular node having a lowest associated unicast routing cost to the multicast listener device from among the candidate nodes, and joins the multicast tree at the selected join point.

  • Patent number: 10560277
    Abstract: Systems and methods for providing multicast group multicast local identifier (MLID) dynamic discovery on received multicast messages for a relevant multicast global identifier (MGID) in a high performance computing environment. By allowing InfiniBand (IB) clients to associate local queue pairs (QPs) with the MGID(s) of relevant multicast group(s) without requiring any join request to the subnet manager (SM)/subnet administration (SA), it is possible to receive relevant multicast (MC) messages without imposing the SM/SA overhead of a conventional multicast group join request. After receiving, at an end-node of the subnet, a multicast packet including a multicast global identifier and a multicast local identifier, the end-node can inspect the multicast packet to learn the multicast local identifier and include the learned multicast local identifier in the multicast group record at the end-node for the received multicast global identifier.

  • Patent number: 10560284
    Abstract: Aspects of the present disclosure involve methods and systems for mapping network service paths between endpoint devices of a network. An aggregate network traffic database is used to store network traffic data retrieved from network devices of a network. A network service mapper then queries the database using endpoint device identifiers corresponding to endpoint devices to determine which network devices interacted with the endpoint devices during provisioning of previous network service instances. The set of network devices is then compared and analyzed to determine one or more network service paths between a pair of endpoint devices. In certain implementations, network architecture rules and/or network device configuration data is also analyzed to determine an order of the network devices along the one or more network service paths.

  • Patent number: 10554428
    Abstract: A method which is implemented by an access point, and in which requests are received from a number of user devices, in which each of the requests specifies one or multiple requested file blocks of at least one file. A set of multicast groups is determined based on the received requests, and each multicast group contains a set of indices of one or multiple of the user devices and a set of indices of the file blocks which are to be transmitted to the user devices indicated in the multicast group. For each multicast group of the set the file blocks indicated in the multicast group are retrieved and encoded, and a forward error correction process is used. For each of the multicast groups of the set the encoded file blocks indicated in the multicast group are transmitted to the user devices indicated in the multicast group.

  • Patent number: 10547537
    Abstract: In some examples, a controller for a network includes a path computation module that determines, for a plurality of LSPs or other flows having a common source, shortest paths of the network from the common source to respective destinations of the plurality of LSPs based at least on a minimum bandwidth. The path computation module further determines, after determining the shortest paths, a shortest path for the LSP of the plurality of LSPs as the shortest path of the shortest paths of the network from the common source to a destination for the LSP. A path provisioning module of the controller, after the path computation module determines the shortest path for the LSP and in response to the path computation modules routing the LSP to the shortest path for the LSP on a network model of the network, installs the LSP to the network as routed to the shortest path.

  • Patent number: 10547463
    Abstract: Computerized aspects monitor listening virtual local area network ports for multicast packets from hypervisor virtual machines that meet a multicast group definition, and retrieve source addresses for original hypervisor sources of detected ones of the multicast packets, bind the retrieved addresses to the multicast packets to generate encapsulated packets, and forward the encapsulated packets as user datagram protocol unicast packets to a destination address of a virtual extensible helper daemon defined for a destination hypervisor of a second virtual local area network. The destination address meets the multicast group definition for the first virtual local area network, and the second virtual local area network is geographically remote from and different from the first virtual local area network, and thus the aspects send the first user datagram protocol unicast packet through an internet protocol router to the designated receiving port.

  • Patent number: 10491533
    Abstract: A participant in a network is configured to query a data storage system to determine whether there have been any changes to a network. The participant receives a response to the query and determines, based at least in part on the response, whether reconfiguration is necessary. If the network has changed (e.g., if the network topology has changed), as indicated in the response, the system performs one or more actions in accordance with the response. Multiple participants in the network may query the data storage system so that, collectively, network updates are initiated by changes to data in the data storage system. The network may be an overlay network that allows communication according to a communication protocol, such as multicast, that may not be completely supported by a physical network substrate.
