Nowadays, a lot of software secretly uploads and downloads data in the background after installation, which even causes obvious congestion of network speed in serious cases.

It is the same kind of application as P2Pover from China. The two work in a similar principle, and are based on the ARP (Address Resolution Protocol) protocol.
