In particular, the traffic on the FTP control connection is typically periodic in nature and therefore remains in slow start at all times. Furthermore, when multiple files are transferred, the files are sent sequentially. An effect of this is that the cwnd is needlessly decreasing in between consecutive file transfers. This paper addresses this problem and proposes a solution which involves using SCTP instead of TCP. First, the multistreaming feature of SCTP is used to separate the control and data traffic. One stream is used exclusively for control traffic and one for data traffic. Second, pipelining is used to avoid the data stream to become idle in between two file transfers. The pipelining entails starting the file retrieval as soon as the request reaches the server, irrespective of whether a file transfer is already on going or not. Experiments conducted on a FreeBSD implementation of the modified FTP suggest that the transfer latency is cut by more than half. Furthermore, as the loss rate on the connection increases, the relative improvement in transfer latency increases.},
