Problems solved by technology

[0006] 2.1 Disadvantages of Ethernet
[0009] 2.1.1 Physical address issues
Collision is determined by the nature of the shared channel and is inevitable, which leads to a decrease in Ethernet efficiency
According to the analysis, the rate is 10Mb / s Ethernet, when the frame length is 256 bytes, its efficiency is only about 60%.
[0014] 2.2 Deficiencies of TCP / IP
[0015] In the TCP / IP system, in order to work normally, users need to set some TCP / IP parameters on their computers, such as IP address, gateway address, DNS address, etc. Before being able to work online, the user must set the parameters as required, and then restart the machine to make the parameters take effect, which is a painful process for ordinary users
The second is that since users can set their own IP addresses, hackers can steal the IP addresses of legitimate users and pretend to be legitimate users to perform illegal operations

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] The network of the present invention is a highly simplified network based on the existing network, which can be used in both local area network and wide area network environment.

[0037] 5.1 IP Over Media

[0038] Frame Delimitation (64-bit)

IP packet

CRC (32 bits)

[0039] 5.2 Data transmission method

[0040] Point-to-point, full-duplex, no media access control.

[0041] 5.3 Network composition

[0042] see figure 1 , the network uses the IP switching device 1 as the core, the IP switching device 2 is interconnected with the IP switching device 1, and the IP switching device 2 is connected with the terminal IP switching device 3.

[0043] 5.3.1 IP switching equipment

[0044] In the network, there are two types of IP switching devices: core IP switching device 1 , core IP switching device 2 and terminal IP switching de...

Abstract

A network transmitting IP data package directly on the physical media communicates from point to point in duplex operation mode without media visit control function, simplifies the frame packaging and its processing course for increasing the efficiency of transmission an reducing the relay of transmission, uses IP exchange device as a centre for connecting all IP terminal equipment on its interface and in the network IP address of IP terminal equipment will be IP address connected at the interface of IP exchange device without disposing any network parameter on itself as IP address of IP exchange device interface corresponding to each IP address of IP terminal equipment for quarding against address embrzzlement and increasing the network security.

Description

1. Technical field [0001] The present invention relates to computer application technology and the structure, transmission mode and equipment of computer information network, specifically, a network that directly transmits IP data packets on physical media. 2. Background technology [0002] With the rapid popularization of the Internet and the gradual expansion of the application field, most LANs have become or will become a member of the Internet. As we all know, the Internet is a network based on the TCP / IP protocol. In order to be able to connect to the Internet, almost all current computer networks provide support for the TCP / IP protocol. Not only that, but it can be further predicted that the future network is likely to be dominated by TCP / IP. The following description is based on the premise that "the future network will be unified with TCP / IP". [0003] But TCP / IP itself does not define the data link layer and the physical layer, and it can use the existing protocol...
