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 ...
