Replicate Messages For Multiple Destination Distribution Patents (Class 370/390)
  • Patent number: 12047277
    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: 12003409
    Abstract: Techniques and mechanisms for a control plane approach for dense topologies that focusses on discovering shared ECMP groups in the control plane independent of per-prefix learning and then learning prefixes via these shared ECMP groups instead of learning prefixes via one next-hop at a time. In dense topologies, this approach helps minimize BGP path scale, corresponding signaling and enables control plane scaling that is an order of magnitude higher than a traditional eBGP control plane. During link and node topology changes, the described control plane approach enables control plane signaling that is prefix independent and an order of magnitude lower. A control plane approach to path-list sharing and prefix independent signaling on link and node topology changes enables prefix independent convergence (PIC) in scenarios that would not be possible otherwise with traditional FIB driven path-list sharing and PIC.

  • Patent number: 11799659
    Abstract: Method, devices, programs and system for the realization of an encrypted protocol for the transmission of encrypted data packets, called “Transport Encrypted Protocol” (TEP), intended for communication, characterized by a particular methodology of data encrypted encapsulation according to the blockchain paradigm including the following steps: the establishment of a distributed ledger which generate sender and recipient addresses to establish a communication characterized by the encryption of both the content and the transport channels; the verification of the integrity of the message and the correct correspondence of the address by the receiving node (hash), which decrypts each layer of encapsulation and hence decrypting the message itself; and the submission of an encrypted notification of receipt to the sender node and the subsequent preparation of the receiving node to the next state, either the break in communication or the modification of its status from recipient to sender.

  • Patent number: 11749313
    Abstract: In accordance with one or more aspects, a request to run an application is received. The application has an associated tune manifest that identifies one or more resources that the application may use. The tune manifest is compared to a device resource record, and a check is made, based at least in part on the comparing, whether the one or more resources identified in the tune manifest can be satisfied by the device. If the one or more resources identified in the tune manifest can be satisfied by the device, then the application is run; otherwise, a notification of a conflict between the application and the device is presented. Additionally, when the application exits, a device tune state that identifies a content source to which the device was tuned prior to running the application can be retrieved and the device restored to this device tune state.

  • Patent number: 11743067
    Abstract: A method includes receiving, at a first edge node, an Internet Protocol (IP) multicast address of a first silent host node. The method further includes receiving, at a second edge node, an IP multicast address of a second silent host node. The IP multicast address of the first silent host node is equal to the IP multicast address of the second silent host node. The method further includes storing the IP multicast address of the first and second silent host node in a shared entry of a routing table. The method further includes receiving, at a third edge node, a packet from a third host node and determining that a destination address of the packet corresponds to the IP multicast address stored in the shared entry of the routing table.

  • 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: 11736391
    Abstract: For a managed network including multiple host machines implementing multiple logical networks, some embodiments provide a method that reduces the memory and traffic load required to implement the multiple logical networks. The method generates configuration data for each of multiple host machines including (i) data to configure a host machine to implement a set of logical forwarding elements that belong to a set of routing domains and (ii) identifiers for each routing domain in the set of routing domains. The method then receives data regarding tunnels endpoints operating on each of the host machines and an association with the routing identifiers sent to the host machines. The method then generates a routing domain tunnel endpoint list for each routing domain based on the data received from each of the host machines including a list of the tunnel endpoints associated with the routing domain which the host machines can use to facilitate packet processing.
