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.
Claims20
A first network device, comprising:
- one or more processors;
- and
- a non-transitory computer readable medium storing a program to be executed by the one or more processors, wherein the program comprises instructions that when executed by the one or more processors, cause the first network device to perform operations comprising:
- transmitting, according to a network protocol, a data packet to a second network device, wherein the data packet comprises loopback request information in a header of a layer of a network model, and the network model includes a Transmission Control Protocol/Internet Protocol (TCP/IP) model;
- and
- receiving a loopback reply packet comprising, in a payload, at least a portion of the data packet including at least one header of the data packet, wherein the loopback request information requests the second network device to transmit the loopback reply packet to the first network device.
A first network device, comprising:
- one or more processors;
- and
- a non-transitory computer readable medium storing a program to be executed by the one or more processors, wherein the program comprises instructions that when executed by the one or more processors, cause the first network device to perform operations comprising:
- receiving, according to a network protocol, a data packet from a second network device;
- and
- transmitting, in response to the received packet comprising loopback request information in a header of a layer of a network model, a loopback reply packet to the second network device, wherein the loopback reply packet comprises, in a payload, at least a portion of the received packet including at least one header of the received packet, and the network model includes a Transmission Control Protocol/Internet Protocol (TCP/IP) model.
A method, comprising:
- transmitting, by a first network device, according to a network protocol, a data packet to a second network device, wherein the data packet comprises loopback request information in a header of a layer of a network model, and the network model includes a Transmission Control Protocol/Internet Protocol (TCP/IP) model;
- and
- receiving, by the first network device, a loopback reply packet comprising, in a payload, at least a portion of the data packet including at least one header of the data packet, wherein the loopback request information requests the second network device to transmit the loopback reply packet to the first network device.
