Problems solved by technology

[0005] But there is still a problem with this solution: when the ISP upgrades to a new IP domain required by the TCP / DN / IP protocol, because of the limited types of mainstream operating systems, the hosts in this domain can be easily upgraded to TCP / DN / IP through the upgrade operation. protocol stack, but there are many types of application software on the host, and it is usually difficult to update all of them in a short period of time, and some application software that are no longer maintained by others will never even be able to be upgraded to support the TCP / DN / IP protocol stack
[0010] However, there is a problem with this standard encapsulation method: the interface of the sending function based on the TCP / IP protocol stack and the sending function based on the TCP / DN / IP protocol stack are different
Traditional TCP / IP-based network applications will not be able to be carried on the TCP / DN / IP network

Embodiment Construction

[0057] The above-mentioned features and advantages of the present invention can be better understood after reading the detailed description of the embodiments of the present disclosure in conjunction with the following drawings. In the drawings, components are not necessarily drawn to scale, and components with similar related properties or characteristics may have the same or similar reference numerals.

[0058] The embodiment of the conversion method of TCP / DN / IP network compatible TCP / IP network

[0059] Figure 10 shows a schematic diagram of the TCP / DN / IP protocol stack, image 3 It shows a standard TCP / DN / IP protocol stack encapsulation flow chart. From image 3 It can be seen from the figure that when the host assembles the header of the domain name layer of the TCP / DN / IP message, it needs to fill in the domain name of the target host. Type and user data are passed as parameters. However, after the message is passed from the domain name network layer to the IP ne...

Abstract

The invention discloses a conversion method and message transmitting and receiving method for a TCP / DN / IP network compatible with a TCP / IP network. Transparent conversion can be carried out on a message sent by an application, between TCP / IP package and TCP / DN / IP package. The technical scheme is that through design of a package / unpackage process different from an OSI network model and through utilization of a pseudo address technology, the IP message sent by the application is transparently converted into the message of a TCP / DN / IP package format, so the message can be normally forwarded among different IP domains defined by a TCP / DN / IP protocol, and the message is normally restored at a receiving end. In this way, the TCP / DN / IP protocol can be completely compatibly used for bearing the traditional network application realized based on the TCP / IP, and an upgrading process is very smooth.

Description

technical field [0001] The invention relates to Internet technology, in particular to technology related to IP network address space expansion. Background technique [0002] IPv4 is a network designed for the US military. It only uses 32-bit addresses and can accommodate up to 4.3 billion hosts. With the rapid expansion of IP networks, IPv4 addresses have been exhausted. [0003] The industry has successively introduced NAT technology and IPv6 technology to solve the problem of insufficient addresses. However, NAT technology destroys the symmetry of the network, and IPv6 faces great difficulties in promotion because it is incompatible with existing networks. [0004] The article "Double Network Layer Solution - A New Next-Generation Internet Solution" published in the 8th issue of "Telecommunications Science" in 2014 introduced a new solution to the shortage of IPv4 addresses. This solution expands a new layer vertically on the IP protocol stack, and can expand unlimited ...
