The impact is too great! The dial-up difference is so critical

The Internet is the most basic need. No one can deny this. However, whether the young partners understand that dial-in dial-up differences between the dial-up, the impact of the place can vary widely. Do not believe Xiao Bian will tell you, you will understand after reading.

Let’s talk about the main way we go online today. Whether it is residential broadband or broadband services provided by telecom operators, most of them are now connected to the Internet through PPPoE's virtual dialing method. However, there are about three options for using dial-up devices. These three differences are very large.

tips:

PPPoE stands for Point to Point Protocol over Ethernet, which means Ethernet-based point-to-point protocol. This protocol is the latest developed standard to meet the communication between more and more broadband internet devices and faster and faster networks. It is based on two widely accepted standards: LAN Ethernet and PPP point-to-point dial-up protocols. The essence of PPPoE is a relay protocol between Ethernet and dial-up networking. He inherits the advantages of Ethernet's fast and simple PPP dialing, user authentication, and IP allocation. This makes PPPoE more advantageous than other protocols in broadband timing access services.

Cat Cat Dial

The first type is direct dialing of optical cats, and now a way that telecom operators love to promote, after installing the optical cat, fill in the dialing account and password into the cat's PPPoE dialing interface, as long as the cat is powered on and dial up automatically. . All devices connected to the cat in the home, whether wired or wireless, are always online. Moreover, this way of using cats to dial in the family-based network environment, can be considered a first-class routing (light cat built-in routing function), which has some inherent advantages.

The most important point is that UPNP and port mapping are convenient. UPNP means plug and play. This function has a very important role for P2P and some games. Computer or mobile application requests port mapping, which can be mapped automatically by UPNP function. The port communicates with the outside world. Simply put, P2P downloads like Thunder and some online games rely heavily on this feature.

However, the problem faced by cats is also very obvious. The first is the problem of traffic distribution. The ability of ordinary cats is not strong, which will affect the Internet experience. To give a chestnut, a PC in the home full-speed P2P download, another mobile phone to watch online video buffer is much slower, which is the lack of flow control capabilities of the device.

Another problem is related to security issues - direct dialing will cause the cat to be exposed to the Internet itself. In fact, this is nothing. In any case, Optical Cat has a username and password. However, almost all models of the cat have a unified username/password, and it is almost already public, which means that there is a risk that “hearted people” may infiltrate your network.

Routing dial

Compared to optical cat direct dialing, Xiao Bian is still strongly recommended to use route dialing. Simply put, it is connected from the LAN port of the cat to the router's WAN port, using the router's built-in PPPoE dial-up Internet access (light cat is bridge mode). In contrast, routing drives cats to dial, setting more rich, such as UPNP features can be used, but also to avoid light cats exposed on the network (light cats, routing are hidden).

And what to download offline using routing, port mapping, firewalls and the like can be set according to their own requirements, game players can also do not have to worry about network online game players can not find people (more network level penetration ability weaker, light cat + There is no problem with routing two-tier networks.)

In addition, it is very important that the routers all have similar flow control functions, which can fully guarantee that all devices in the LAN can be reasonably allocated to the appropriate bandwidth and connection priority. When downloading online video, it will not fail, even if It is not affected by playing the game.

However, compared to the setting of the route of light cat dialing, it is still a bit more complicated, Xiao Bian will specifically push a set of content. However, if possible, Xiao Bian still highly recommends using routing dialing. In fact, the vast majority of users are still hanging a wireless router after the cat, isn't it?

Computer dialing

The last is the computer dialing, this method is the most traditional dialing method, but also based on PPPoE. However, this method is used very little now, because the home network is not only a device for a computer, but also for a mobile phone. If you use a computer dial-up Internet access, but also open WiFi sharing features, set up trouble, use very inconvenient. However, this method is not without advantages, routing or cats, dial-up Internet access is always online, some special circumstances such as timing broadband users, it is clear that computer dial-up Internet access is more appropriate, after all, can independently control the length of the Internet.

In general, the best choice for lazy people is natural cat dialing. If you choose this dialing method, be sure to think of ways to enter the DMZ function into the light cat to map an IP address without a device on the intranet (obtaining the super password, part You need to crack the optical cat to avoid exposing the cat to the Internet. If it is timed broadband, computer dialing is the best choice. Finally, if possible, use route dialing is the best, taking into account security and networking performance, functions. .
