Embodiment Construction

[0137] The technical solution in this application will be described below with reference to the accompanying drawings.

[0138] figure 1 It is a schematic architecture diagram of a communication system 100 according to a communication method and device of the present application. The system 100 includes a first device 110 , a router 120 , a router 130 and a second device 140 , and the first device 110 and the second device 140 send and receive messages through the router 120 and the router 130 . The system 100 may be a schematic architecture diagram of an Internet of things (Internet of things, IoT) network, a closed networking scenario, and a traditional IP network.

[0139] It should be noted, figure 1 The illustrated system is only for a clearer understanding of the present application, and should not be particularly limited to the embodiments of the present application. remove figure 1 In addition to the devices shown in , the network architecture may also include othe...

Abstract

The invention provides a communication method and device, so that the position and the length of information carried by a data packet header are flexible and variable, a fixed length and an appointedposition are not needed, and compared with a traditional protocol, the communication method is higher in flexibility and better in expandability. The method comprises the steps that a first device obtains a data packet, the data packet comprises a first packet header, the first packet header comprises first indication information and a value of the first packet header information, the first indication information is used for indicating the position of the value of the first packet header information, and the first packet header information is identification information of the device; the firstdevice processes the data packet.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a communication method and device. Background technique [0002] In the prior art, in order to solve that in some scenarios, the addresses provided by the fourth version of the Internet Protocol (Internet Protocol Version 4, IPv4) cannot meet the communication requirements, the sixth version of the Internet Protocol (Internet Protocol Version 6, IPv6) is proposed. ). The header of the IPv4 protocol message is fixed at 20 bytes without considering the option field, among which the source address and destination address each station has 4 bytes (32 bits). The header of the IPv6 protocol message is fixed at 40 bytes without considering the extension header, and the source address and destination address each occupy 16 bytes (128 bits). In order to parse the packet normally, the packet must be encapsulated in strict accordance with the IPv4 / IPv6 protocol, so that the so...
