DETECTING AND COMMUNICATING WITH SILENT HOSTS IN SOFTWARE-DEFINED NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039839 titled 'DETECTING AND COMMUNICATING WITH SILENT HOSTS IN SOFTWARE-DEFINED NETWORKS

Simplified Explanation

The abstract describes a patent application related to discovering silent hosts in a software-defined network (SDN) and directing traffic to these hosts in a scalable and targeted manner. The invention involves determining interfaces of a fabric device that are connected to endpoints in the network fabric. If an address of an endpoint connected to an interface is not available at the fabric device, a notification is transmitted to the control plane of the SDN. The control plane creates a flood list that includes the fabric device, allowing traffic intended for the endpoint to be received by the fabric device based on the flood list.

  • The invention is about discovering silent hosts in a software-defined network and directing traffic to them efficiently.
  • It involves identifying interfaces of a fabric device connected to endpoints in the network fabric.
  • If an endpoint's address is not available at the fabric device, a notification is sent to the control plane of the SDN.
  • The control plane creates a flood list that includes the fabric device.
  • Traffic intended for the silent host is received by the fabric device based on the flood list.

Potential Applications:

  • Improved network management and traffic routing in software-defined networks.
  • Efficient discovery and utilization of silent hosts in a network fabric.
  • Enhanced scalability and targeted traffic routing in software-defined networks.

Problems Solved:

  • Discovering and directing traffic to silent hosts that are not directly addressable by the fabric device.
  • Efficient utilization of network resources by leveraging silent hosts.
  • Scalability issues in managing and routing traffic in software-defined networks.

Benefits:

  • Improved network performance and efficiency by utilizing silent hosts effectively.
  • Scalable and targeted traffic routing in software-defined networks.
  • Enhanced network management and resource utilization.


Original Abstract Submitted

systems, methods, and computer-readable media for discovering silent hosts in a software-defined network and directing traffic to the silent hosts in a scalable and targeted manner include determining interfaces of a fabric device that are connected to respective one or more endpoints, where the fabric device is configured to connect the endpoints to a network fabric of the software-defined network. at least a first interface is identified, where an address of a first endpoint connected to the first interface is not available at the fabric device. a first notification is transmitted to a control plane of the software-defined network based on identifying the first interface, where the control plane may create a flood list which includes the fabric device. traffic intended for the first endpoint from the network fabric is received by the fabric device can be based on the flood list.
