Two computers sharing the Internet solution

With the popularization and development of broadband, more and more websites begin to offer free or charge online movie on demand to netizens. Similar to BT downloads, watching movies online can also be a way to compare Internet bandwidth. Usually, we see the online movie transfer rate as 384kbps--880kbps. The higher the quality of video and audio, the greater the bandwidth consumed, and BT download? The download rate for 300Kbps seems relatively rare, but more than 100Kbps of uploads are not uncommon. Especially when you're in the middle of a download, or if you have something that's really scarce. and QQ and SKPE also have MSN Video communication only need about 20Kbps of bandwidth, general HTTP and ftp download, sometimes you can get more than 1M of bandwidth. However, I believe this time will be very short. (Computer science)

Next, let us do a simple analysis of the shared Web form;
　　
(Alpha G3 Home router map)

1, pure wired network scheme;

Scenario Description:

Routers: Alpha G3 Router (1 WAN ports, 4 LAN ports)

Maximum sharing possible: 4 PCs;

Wiring way: Need to connect 4 computers through twisted pair;

2, the program description:

ADSL home is more suitable for the installation of routers, if your every bedroom has telephone line sockets, you may wish to put ADSL modem and router in the nearest neighbor or the most convenient wiring room or location. So as to minimize the length of the network cable across the home when two households are shared. Of course, the premise is that the computer is also relatively easy to connect. Because it is two share the Internet, so connect ADSL router and ADSL modem to ensure 24 hours All-weather operation. From the power point of view, ADSL modem power Consumption is 12-15 W, and Alpha G3 router's power consumption is only 9W, if the one-month 30-day uninterrupted use, ADSL and router total electricity consumption of up to no more than 15 degrees, That is to say, the electricity charge of ADSL is not more than 10 yuan per month. Two share the electricity tariff 5 yuan per household, although the power of the way there is a waste of state electricity suspicion ... But at least in terms of the family networking programme, half or more of the Internet costs have been saved. The equivalent of each household only need to use "limited time monthly fee" access to the "Monthly Unlimited" Internet service. What needs to be explained is that now any home router supports MAC address cloning, therefore, there is only one IP address shared on the Internet, that is, two computers sharing an IP address.

Networking Advantages:

1, Alpha G3 router power consumption is lower than the wireless router;

2, Alpha G3 router's retail price is only 99 yuan, the purchase cost is low;

Networking disadvantage:

1, Alpha G3 routers need network cable Connection, wiring is a troublesome thing, temporary wiring is also subject to the specific furniture layout and house type restrictions;

2, only 4 LAN Kou, so the largest can only 4 families to share the Internet;

This figure does not use a professional network topology, but through the layout diagram visualization of the Family sharing network when the specific connection mode;

Need to buy hardware in addition to the Alpha G3 home router is also required, Alpha 10m/100m network card (if you already have a network card, or a onboard network card, you can save a sum of money)
