Patent number: 11658945Abstract: A network device includes a transmitter and a receiver to establish a secure connection with one or more network nodes as part of a Autonomic Control Plane (ACP) network. The network device also includes a processor coupled to the transmitter and receiver. The processor receives a request from an application to initiate a connection with a destination network node. The processor also receives packets from the application for transmission toward the destination network node. When the packets from the application are unencrypted, the processor end-to-end encrypts the unencrypted packets without notifying the application. The transmitter then transmits the encrypted packets towards the destination network node across the ACP network.Type: GrantFiled: September 23, 2020Date of Patent: May 23, 2023Assignee: Futurewei Technologies, Inc.Inventors: Toerless Eckert, Sheng Jiang, Bing Liu
