Replicate Messages For Multiple Destination Distribution Patents (Class 370/390)
  • Patent number: 11916776
    Abstract: A method for execution by a processor of a host having an external interface for connection to at least one other network element of a packet-based data network, the host storing a routing table and implementing a container connected to a bridge, the container being addressable by an internal address on a bridge network associated with the bridge. The method includes obtaining an indication of a request for the container to join a multicast group. In response to the obtaining, a request is sent via the external interface for the host to join the multicast group. The routing table may be modified so as to make the bridge a next hop for future packets obtained from the external interface and destined for the multicast group. The routing table may also be modified so as to make the external interface a next hop for future packets that are obtained from the bridge, whose source address is the internal address of the container and that are destined for the multicast group.

  • Patent number: 11743233
    Abstract: Techniques are disclosed for scaling an IP address in overlay networks without using load balancers. In certain implementations, an overlay IP address can be attached to multiple compute instances via virtual network interface cards (VNICs) associated with the multiple compute instances. Traffic directed to the multi-attached IP address is distributed across the multiple compute instances. In some other implementations, ECMP techniques in overlay networks are used to scale an overlay IP address. In forwarding tables used for routing packets, the IP address being scaled is associated with multiple next hop paths to multiple network virtualization devices (NVDs) associated with the multiple compute instances. When a particular packet directed to the overlay IP address is to be routed, one of the multiple next hop paths is selected for routing the packet. This enables packets directed to the IP address to be distributed across the multiple compute instances.

  • Patent number: 11683535
    Abstract: Systems and methods for capturing and distributing a live audio stream of a live event in real-time to a plurality of mobile computing devices are described. The system comprises at least one memory configured to store computer-executable instructions and processing device(s) coupled to the at least one memory and at least one audio input device configured to receive the live audio stream. Upon receipt of the live audio stream, the processing device(s) generate, in real-time, a plurality of discrete audio data packets from the live audio stream, and transmit that respective discrete audio data packet over a first network for receipt by the mobile computing devices. In respect of each one of the discrete audio data packets, a copy of the discrete audio data packet is transmitted for receipt by each one of the mobile computing devices prior to transmitting another one of the discrete audio data packets.

  • Patent number: 11671348
    Abstract: A system that can facilitate multicast forwarding via overlay multicast tunnels in a network is provided. The system can operate as a tunnel endpoint and form a first overlay tunnel with a peer tunnel endpoint. During operation, the system can receive a join request for a multicast group via the first overlay tunnel. The system can identify a local port of the system associated with the multicast group indicated by the join request. The system can then include the first overlay tunnel in a set of forwarding tunnels for multicast traffic of the multicast group based on the join request. Subsequently, the system can forward the multicast traffic of the multicast group received from a local port via the set of forwarding tunnels, thereby limiting forwarding of the multicast traffic to tunnel endpoints associated with the multicast group.

  • Patent number: 11658888
    Abstract: A network timing view provides enhanced visualization for synch timing in support of mobile (4G/5G deployments) and others requiring sync. It allows network managers to view relevant synch data both textually and graphically displayed on the network map nodes and links in a unified view. The user is able to select the appropriate filter on the network map to show the 1588/SyncE connectivity and relevant nodes that are participating in delivering timing. It allows a user to trace the timing path from any timing device upstream to the clock source. It also allows the user to interactively discover and navigate downstream timing paths from any timing device, similar to exploring a tree hierarchy. The timing topology and path data provided allows a user to investigate the timing network for troubleshooting purposes such as timing alarms and events, sync problems, clock quality levels and clock states.

  • Patent number: 11658901
    Abstract: Techniques are disclosed for session-based routing of multipoint Open Systems Interconnection (OSI) Model Layer-2 (L2) frames of an L2 network extended over Layer-3 (L3) networks. In one example, L2 networks connect a source device to an ingress router and receiver devices to egress routers. An L3 network connects the ingress and egress routers. The ingress router receives, from the source device, a multipoint L2 frame destined for the receiver devices. The ingress router forms, for each egress router that is connected to at least one multipoint receiver device, a unicast L3 packet for the L2 frame and forwards the unicast L3 packet to the egress router. Each egress router generates, in response to receiving the unicast L3 packet, the multipoint L2 frame and forwards, to the receiver devices, the multipoint L2 frame.

  • Patent number: 11646961
    Abstract: Technology related to processing network packets in a subscriber-aware manner is disclosed. In one example, a method includes selecting one or more subscribers to move from a first network processing node to a second network processing node. In response to the selection, subscriber data associated with the one or more subscribers can be programmed at the second network processing node. After the subscriber data associated with the one or more subscribers is programmed on the second network processing node, a software defined network (SDN) switch can be reprogrammed to forward network traffic having network addresses associated with the one or more subscribers to the second network processing node instead of the first network processing node.

  • Patent number: 11611507
    Abstract: Some embodiments provide a method for maintaining a virtual network that spans at least one cloud datacenter separate from multi-machine edge nodes of an entity. This method configures a gateway in the cloud datacenter to establish secure connections with several edge devices at several multi-machine edge nodes (e.g., branch offices, datacenters, etc.) in order to establish the virtual network. The method configures the gateway to assess quality of connection links with different edge devices, and to terminate a secure connection with a particular edge device for a duration of time after the assessed quality of the connection link to the particular edge device is worse than a threshold value. In some embodiments, the gateway is configured to distribute routes to edge devices at the edge nodes, and to forgo distributing any route to the particular edge device along the connection link for the duration of time when the assessed quality of the connection link is worse than (e.g., less than) a threshold value.
