Problem: Some small groups use ADSL Internet, which is connected via PPPoE, usually allowing only one client to connect. How do we expect several people to surf the internet at the same time? Or broadband Internet access allows only one user, how to do it.
Scenario Model:
Model: If you have a hardware that acts as a client, connect directly to the server provider, and the same network of users through the hub to connect to the hardware, the problem is solved, for example: there is a government department, which has several branches, a is the general manager of the Department (here is the server provider, such as: telecommunications), B, C, D are among the information department staff, but a just want a representative of the information department to come out and talk to it, the real problem is easy to solve, B, C, D elect a person as the head of the information department, here is E (which is the hardware we just mentioned), A and E direct session, e sessions with BCD. We are the BCD in this virtual example.
The term in the computer for the model above is that e acts as a router in the information department with a routing function, all information from a is distributed through it to the staff, staff members want to visit other departments, and they need to go through e and forward to other places.
So what's the minimum requirement for this hardware e? First, it has an intermediary role; second, look at the way you surf the Internet, may also need to provide automatic dialing, or always online features, such as b do not want to, then C can continue, all the connections are handled by E, BCD is not interested in these connection processing, they only need to obtain their own basic requirements, that is the Internet. As you can see from here, in fact E is inserted as an abstraction layer, and all the complex things are handled intact.
Extended:
The internet is connected to other points by a point.
Solution:
There are two main options available to address these issues:
1 The first is through the purchase of a router (ADSL cat Some integrated routing functions, such as km300a), which is implemented through hardware, but also can have a firewall function, is called a complete abstraction layer. But this is a very demanding program, first of all, the cost of purchasing hardware (cheap hundreds of on the line), and then need a understand the configuration of the routing function of the programmer to set up, the network to be more familiar with, sometimes there are problems need to maintain (this is not a one-time money can be solved). However, this scheme should be preferred, because in terms of security, stability and so can be guaranteed, while Linux and other machines can also set IP address to connect with this router.
2 Software Routing Solution:
Simple users in Windows don't worry, now there is a Chinese software homeshare under Windows, which can support the simple routing function of the first scheme. Setup is simple and can accomplish basic functions of Internet demand.
On the use and download of Homeshare, you can search for downloads on Google, tutorials can also refer to the software accompanying the tutorial to use. (Note: This is a charging software, with the ability to support the author).
