My notebook uses campus WIFI and downloads things with Thunder. It is reported that there is a P2P network ban. What is this and how to solve it?

Well, personally, this should be related to the bandwidth and related settings of the school.

During the day, the school is in office, and there are more people surfing the Internet, which takes up a large amount of natural bandwidth. In particular, the school will definitely set the upper limit of which Ip address segments, and departments, office teaching, teachers, students and workers will definitely have the lowest upper limit. So the speed is slow.

P2P is a kind of peer-to-peer communication, which is different from the client-server model. The client can download a lot of things directly from the server, and generally only needs to submit a small amount of demand information to the server. For example, peer-to-peer communication, or electric donkey refers to the client that communicates with you, not the server. When you download files (especially large files), these peers are the same as yours, and you also download what you need from your computer. This process is determined by the software settings you installed, such as Thunder and Electric Donkey.

The principle of P-P is not detailed. From the above, we can know that when you use PtoP software, your actual traffic is the traffic you download plus the traffic you upload to others, which can be considered as twice or sometimes even more. Moreover, because PP communication has no limitation of server bandwidth, its own traffic exchange is large (which is one of the reasons why p-p communication downloads quickly and small servers can't reach it). ), the burden of campus network is greater. So schools must be banned. However, because people who surf the Internet now don't know what PtoP is, schools can't pursue it, and they can't really ban it. They can only limit the speed. So the speed is busy during the day.

There are fewer people surfing the internet at night, so the speed is improved.

Of course, it is also possible that the school lifted the restriction of PtoP at night. After all, teachers and staff also need to use it, and the network is empty without it. Anyway, this is well controlled by the system.

Well, that's it. Personally, I think this is the case. Nothing special.
