  • Patent number: 11570097
    Abstract: The disclosure provides an approach for an overlay broadcast network for management traffic. Techniques are provided for updating an underlay network route for a virtual computing instance (VCI) on a new host. After activating the VCI on the new host, a routing table on the old host is reprogrammed to associate an Internet protocol (IP) address of the VCI to an overlay broadcast network IP address and a routing table on the new host is reprogramed to associate the first IP address to a local route on the new host. The VCI sends a message to an application programming interface (API) endpoint to initiate reprogramming of an underlay network route to associate the first IP address to the new host. When a response packet is received at the old host, via the underlay network, the old host broadcasts the packet to the overlay broadcast network.

  • Patent number: 11570062
    Abstract: In one embodiment, a network quality assessment service that monitors a network obtains multimodal data indicative of a plurality of measurements from the network and subjective perceptions of the network by users of the network. The network quality assessment service uses the obtained multimodal data as input to one or more neural network-based models. The network quality assessment service maps, using a conceptual space, outputs of the one or more neural network-based models to symbols. The network quality assessment service applies a symbolic reasoning engine to the symbols, to generate a conclusion regarding the monitored network. The network quality assessment service provides an indication of the conclusion to a user interface.

  • Patent number: 11546242
    Abstract: Example methods and systems for logical overlay tunnel monitoring are described. One example may involve a first computer system obtaining control information identifying a list of multiple logical overlay tunnels to be monitored, including a first logical overlay tunnel between a first virtual tunnel endpoint (VTEP) and a second VTEP. Based on the control information, a first monitoring agent may configure and inject a probe packet at the first VTEP to cause the first VTEP to perform encapsulation and send an encapsulated probe packet over the first logical overlay tunnel. In response, an encapsulated response packet that includes a response packet may be received from the second monitoring agent over the first logical overlay tunnel. Based on the response packet, a tunnel performance metric associated with the first logical overlay tunnel may be determined.

  • Patent number: 11470491
    Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

  • Patent number: 11463276
    Abstract: Described herein are systems and methods providing a multi-dimensional ring-lattice network topology. Systems and methods disclosed herein provide for constructing network topologies in a form of a partial mesh (a partially connected network), where a bridge is capable of forwarding packets through other bridges when a direct link to the destination compute device is not available. A temporary on-demand tunnel is created by virtual networking software on-demand, to facilitate a direct tunnel between two virtual network interfaces where such a direct connection is not available with a permanent tunnel, and where there is sufficient traffic demand between these two interfaces that justifies a direct tunnel. The described approach provides a framework for achieving a compromise between link count limitation, and packet-forwarding path length, that can be tailored to address particular network requirements, together with a way to reliably predict the performance of the resulting network.

  • Patent number: 11463968
    Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) burst set patterns in which SSs and broadcast channel transmissions may be transmitted (e.g., in time). A base station may identify a SS burst set pattern indicating positions (e.g., time locations) for SS block transmissions, for example, in bandwidth restricted communication systems. The SS burst set pattern may be determined based on numerology or subcarrier spacing associated with SSs and non-SSs. The base station may transmit an indication of the SS burst set pattern to a wireless device. The wireless device may receive the indication of the SS burst set pattern and determine one or more time locations of SSs (e.g., primary synchronization signal (PSS), secondary synchronization signal (SSS), physical broadcast channel (PBCH) of a SS block). The wireless device may then monitor the identified positions for SSs.
