Embodiment Construction

[0031] 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 combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0032] figure 1 is a flow chart of the network forwarding method according to the first embodiment of the present invention.

[0033] The network forwarding method can be understood as a network address translation method, which is used to realize the mutual conversion of the IP addresses of different IPv4 devices and IPv6 devices, thereby ensuring data intercommunication between the IPv4 devices and the IPv6 devices.

Abstract

The invention provides a network forwarding method and device. The method includes the steps of obtaining IP addresses and network types of access network devices, configuring an address mapping table between the network devices, obtaining the source IP address, the target IP address and request data of the IPv4 network type of a request message when receiving the request message for allowing the IPv4 device to have access to the IPv6 device, converting the source IP address and the target IP address of the IPv4 network type into the source IP address and the target IP address of the IPv6 network type according to the address mapping table, repackaging the source IP address, the target IP address and request data of the IPv6 network type to form a message, and sending the message to the corresponding IPv6 device. By configuring the address mapping table between the different types of network devices, the address of the message of the IPv4 type is converted into the address of the message of the IPv6 type when the message is received, and therefore data intercommunication and network mixing of the IPv4 device and the IPv6 device are achieved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network forwarding method and equipment. Background technique [0002] The current protocol suite adopted by the global Internet is Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol, TCP / IP). IP is the protocol of the network layer in the TCP / IP protocol suite, and is the core protocol of the TCP / IP protocol suite. Currently, the version numbers of the IP protocol include IPv4 and IPv6. [0003] IPv4 is the fourth version of the Internet Protocol (IP), and the first widely used protocol that forms the cornerstone of today's Internet technology. IPv4 can run on a variety of underlying networks, such as end-to-end serial data links (PPP protocol and SLIP protocol), satellite links, the most commonly used Ethernet in LANs, and so on. [0004] IPv6 is the sixth version of Internet Protocol (IP). IPv6 is a next-generat...
