Container virtual network communication method and container virtual network

The invention discloses a container virtual network communication method and a container virtual network. The method comprises the following steps: a sending end embeds virtual network addressing information into a free bit of a physical network addressing field to obtain a message in a physical network addressing format and sends the message; and the receiving end receives the message based on the physical network addressing information in the physical network addressing field, takes out the virtual network addressing information from the free bit, and sends the message information to a container corresponding to the virtual network addressing information. According to the inter-container communication scheme, the IPv6 address programming capability is utilized, addressing information of an upper-layer virtual network is embedded into a bottom-layer physical network address at a sending end to be carried, the addressing information is recovered into a needed virtual network addressing format at a receiving e
