Method and system for processing Internet data message

Abstract

The invention discloses a method for processing Internet data message, and a system thereof, wherein a special mark field in the header of an IPv4 data message is examined to determine whether addressextension information exists; if the mark field of the address extension information exists, a 32-bit source address field and / or a 32-bit target address field in the header of the IPv4 data messageis bonded with the data bit of another field in the header of the IPv4 data message to form a source address or a target address more than 32 bits; the mark field is a special address extension option, and the option type code of the address extension option is an unused option type code value reserved in the IPv4 data message, with the total length up to 40 bytes. The technical proposal can realize a data message processing technology and an IP address proposal which remains fully compatible with the IPv4, uses length variable addresses and has 20 address extension levels. According to the invention, the existing IPv4 address as a 'zero-level extension address' is permanently effective, and the allocated and used IPv4 network and system can be continuously used for a long time, while theupgrade of the address is just to introduce a new and longer extension address. The invention adopts a mode of extending the address level by level and concurrently using multilevel addresses, thus coping with the worldwide IPv4 address exhaust in a better way and various changes encountered by the upgrade of Ipv4 technology.

Description

technical field [0001] The invention relates to Internet datagram processing technology in the field of Internet technology, in particular to a method and a system for setting address information at the head of the datagram and transferring the datagram between network nodes according to the information. Background technique [0002] The internetworking technology represented by the Internet makes it possible to transmit data between nodes (computers or various digital devices) located on different networks. Computers in a large number of local area networks distributed around the world can achieve fast and efficient two-way data communication by using standardized Internet protocols, regardless of the different physical characteristics or electronic communication technologies actually used by these local area networks. As we all know, the interconnection protocols used by the Internet are collectively referred to as TCP / IP, which is a set of network interconnection protocol...

Problems solved by technology

It has been 15 years since the IPv6 technical standard was proposed, and the problem of backward compatibility with IPv4 has always been a significant obstacle to the widespread application of IPv6

However, such a technical solution has not yet appeared
