transfer rate limiting

[leocoder0]

Description

Does the sftp server implemented by ssh-sftp have a speed-limited function? If so, how should I limit the transmission rate for different users, such as upload rate and download rate. Is there a corresponding case for reference?

Motivation

In order to prevent excessive use of bandwidth, we will set the maximum transmission rate for different users.

There is no built-in mechanism, but you could achieve this by registering a non-default SftpFileSystemAccessor and override the openFile method to return a file channel that you implement and enforces whatever transfer traffic shaping policy you need.
