  • Publication number: 20220272033
    Abstract: A map server/map resolver (MS/MR) of a Locator ID Separation Protocol (LISP) control plane for an enterprise private network for group-based service insertion is described. The MS/MR may facilitate communications from a first host having a first endpoint ID (EID) and located at a first tunnel router having a first routing locator (RLOC), to a second host having a second EID and located at a second tunnel router having a second RLOC. The MS/MR receives, from the first tunnel router, a map request for requesting an EID-to-RLOC mapping associated with the second EID and including a group identifier. The MS/MR selects a service insertion policy including an address of a service border router for a service that is registered with the MS/MR, and responds with a map reply including the address for populating an overlay route for forwarding communications via the service border router for insertion of the registered service.

  • Publication number: 20220173999
    Abstract: This technology enables directed broadcasts in network fabrics. A control plane node is configured to resolve directed broadcast addresses by mapping the directed broadcast address to a subnet address. A fabric border node receives a directed broadcast, extracts a destination address, and transmits a request to the control plane node to resolve the destination address. The control plane node retrieves the stored mapping and generates a map reply with a multicast destination. The fabric border node encapsulates and forwards the directed broadcast to fabric edge nodes, which decapsulate the directed broadcast and deliver a data set from the directed broadcast to appropriate end point devices. Each fabric edge node may be enabled to determine if the fabric edge node may be connected to a silent host and, based on that determination, request the fabric border node to be added to the multicast destination to receive the directed broadcast.

  • Patent number: 11296985
    Abstract: This technology enables normalized lookup and forwarding for diverse virtual private networks in multi-site network fabric deployments. A source device on a first Layer 2 site transmits a frame to a destination device on the same subnet, but on a second Layer 2 site. The frame is encapsulated and routed to a fabric border node. The fabric border node matches the source subnet to the destination subnet and transmits an address request protocol (“ARP”). In response to not receiving a reply to the ARP, the fabric border node transmits a map request to a Layer 3 transit fabric control plane node. The control plane node extracts a destination identifier from the map request and determines that the destination identifier is a Layer 2 identifier. The control plane node transmits a map reply to the fabric border node, where the frame is re-encapsulated and forwarded to the destination device.

  • Publication number: 20220103424
    Abstract: In one embodiment, dynamic user private networks are virtually segmented within a shared virtual network. A network control system maintains the dynamic logical segmentation of the shared virtual network. User entities (e.g., user devices and/or services) are communicatively coupled to respective personal virtual networks via endpoints of access devices. Each of these endpoints is associated with a corresponding user private network. Responsive in real-time to automated processing of a received electronic particular user request, the network control system automatically modifies the dynamic logical segmentation of the shared virtual network to move a particular user entity on the shared virtual network to newly being on the first dynamic user private network without being disconnected from the shared virtual network. One embodiment uses different user private network identifiers (UPN-IDs) associated with endpoints and received packets to identify their respective user private network.
