Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] Such as figure 1 As shown, it is an embodiment of a method for supporting IPv4 packet transmission provided by the embodiment of the present invention. In this embodiment, the method shows the processing flow of the sending device side, which specifically includes:

[0069] Step S101, the sending device receives the IPv4 message;

[0070] Before the step S101, a step is further included: converting the communication data into the received IPv4 message through the IPv4 protocol stack.

[0071] Step S102, after determining the number of bytes of the IPv6 header and the preset position of the corresponding identification information, carrying the determined IPv6 header to the front end of the received IPv4 message, and adding The conversion identification ID...

Abstract

The present invention provides a method for supporting IPv4 message transmission. The method includes receiving the IPv4 message by a sending device; carry to the front end of the received IPv4 message, and set the conversion identification ID on the preset position of the identification information, so that the received IPv4 message is converted into an IPv6 message; The IPv6 packet is sent to the receiving device. Implementing the embodiment of the present invention can solve the problem of IPv4 message transmission on IPv6 network device communication in the G3-PLC communication unit.

Description

technical field [0001] The invention relates to the technical field of smart grid communication, in particular to a method for supporting IPv4 message transmission, a sending device, a receiving device and a communication network. Background technique [0002] G3-PLC is a global power line communication open protocol specially designed for smart grid communication. It belongs to the Narrow-Band Power Line Communications (NB-PLC) standard and is usually used in automatic meter reading (AMR), energy control and power grid monitoring and other low-speed data communication occasions. With the development of communication technology, due to the IP (Internet Protocol, Internet Protocol) address IPv4 (Version 4, version number 4) we use, the IPv4 address uses 32-bit binary encoding, that is, 4 bytes, and each 8-bit is One group, the range of IPv4 addresses is: 0.0.0.0~255.255.255.255. Since the IPv4 address can only use more than 4 billion IP addresses at most, which is far from ...
