Why P2P Download Leads to Low ADSL Rate

In an Internet cafe using the ADSL service, if a user uses the P2P software for downloading or uploading with the very light traffic, the Internet access rate of the entire Internet cafe will be slow. If the Internet cafe uses the FTTx+LAN mode for Internet access, the Internet access rate is not that slow. Why do these two problems happen?

This is because the upstream ADSL rate and the downstream ADSL rate are asymmetric. Generally, the ADSL upstream bandwidth is low. In addition, downloading and uploading are performed simultaneously through the P2P software. In this case, the upstream bandwidth is congested but the downstream bandwidth is sufficient. Therefore, the P2P communication packets sent from the ADSL end cannot be exchanged successfully. This leads to low downstream rate.

If the FTTx+LAN mode is used, the upstream and downstream bandwidths are the same; thus, congestion does not occur in the upstream direction and the above-mentioned fault does not occur.
