  • Publication number: 20220255856
    Abstract: Provided herein are systems and methods for providing a MAC-based redistribution policy between networks in a multi-area network. A network can have a boundary node that communicates to neighboring networks. Boundary nodes can receive policy updates that identify which services are redistributable across network boundaries. Boundary nodes can receive a packet for a service, translate the packet's encapsulation, and forward the packet across the boundary towards a destination node. Boundary nodes can forward the packet such that it originates in the second network from a virtual node.

  • Publication number: 20220255852
    Abstract: Provided herein are systems and methods for managing redistribution and remapping of multicast services between networks in a multi-area network. Multicast streams can be sent through networks from a source node towards a boundary node. The boundary node can receive the multicast stream, remap a source node identifier and service instance identifier, and forward the multicast stream into a second network. The boundary node can receive a route for the multicast stream. The route can be installed in a link-state database and can be used to send the multicast stream through the multi-area network from the source node to a destination node.

  • Patent number: 11323324
    Abstract: Disclosed herein are system, method, and computer program product embodiments for analyzing a network. An embodiment operates by a third-party component deriving network data based on a received data packet from a network component configured to perform a network function. The third-party component orders a transaction including second network data from a distributed ledger. The third-party component determines that the first and second network data meet or exceed a condition of a smart contract comprising the condition and an associated network action related to the network function. The third-party component sends the condition of the smart contract and the first and second network data to another third-party component. The third-party component receives a validation that the first and second network data meet or exceed the first condition of the first smart contract and performing the first network action on the network.

  • Patent number: 11201814
    Abstract: Implementations relate to configuration of networks using switch device access of a remote server. In some implementations, a method includes sending a request from an edge configuration device to an access control server, where the request requests shortest path bridging (SPB) configuration information for a detected end device connected to the edge configuration device, and where the edge configuration device is connected to an SPB network. The method receives at the edge configuration device the SPB configuration information for the end device from the access control server. The edge configuration device is configured to provide the end device access to the SPB network.

  • Patent number: 11115857
    Abstract: Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated.
