There are several methods to limit FTP bandwidth:
1. FTP Server Configuration: Most FTP servers have a built-in feature to limit the transfer rate. It can be configured by setting a limit on the maximum upload and download speed.
1. Bandwidth Control Software: There are software programs available such as NetLimiter or Traffic Shaper XP that can limit FTP traffic and control bandwidth allocation.
1. QoS (Quality of Service): If the network has a QoS-enabled router, it can be configured to prioritize or limit FTP traffic according to the defined policies.
1. Firewall Rules: Firewall rules can be set up to restrict FTP traffic to a certain port or protocol type. This can help control the overall bandwidth consumed by the FTP transfers.
1. Third-Party Modules: Some FTP servers offer third-party modules that limit bandwidth. For example, the mod\_bwlimit module for Apache server can limit bandwidth usage on a per-virtual-host basis.
