Abstract: A first network device is configured to: transmit data packets and poll messages to a second network device; and receive, in response to each poll message, at least one status message from the second network device. The at least one status message indicates which of the data packets sent before that poll message have been correctly received at the second network device and/or have been lost. The first network device is configured to adapt a rate of transmitting the poll messages based on a set of parameters. Further, a second network device is configured to: receive data packets from a first network device; and transmit at least one unsolicited status message to the first network device, in case of certain conditions.

Abstract: The present disclosure provides example network devices and communication methods. One example method includes transmitting, by a first network device, according to a network protocol, a packet to a second network device. The packet includes loopback request information in a header of a layer of a network model. A loopback reply packet is received. The loopback reply packet includes, in a payload, at least a portion of the packet including at least one header of the packet. The loopback request information requests the second network device to transmit the loopback reply packet to the first network device.
