1. How to Boost File Transfer Speeds
100x Without Increasing Your
Bandwidth

2. So you want to speed up your file
transfers between your office and
other locations . . .

3. Did you know that networks spanning
long distances are subject to high
latency and other factors that result in
poor network conditions?

4. • Factors that can affect file transfer
performance:
– Latency
– Packet Loss
– Bandwidth
– Congestion
• But first, what is a packet?

5. • Information chopped into smaller pieces and
encapsulated into “packets” in order to send via
file transfer.
• Along with information you send (the payload),
each packet comes with additional information,
the TCP Header.
• These packets are sent over the network to the
intended receiver or destination.
• These packets are directly affected by the
network conditions we are about to discuss.

6. • Delay time for a packet
to get from one point to
another.
• The longer the distance,
the greater the latency.
• Properties of the physical
medium can cause
greater delay.

7. • Not all packets you send arrive at their destination.
• Some of them are dropped/lost along the way. This
can happen due to a variety of reasons like:
– Signal degradation
– Faulty networking devices or drivers
– Congestion
• If you're sending a document, even just a single lost
packet can be a big problem because some text and
other portions may end up missing.

8. • Bandwidth: theoretical maximum rate of data transfer
that a network or network device can handle.
• In wide area networks, the actual rate of data transfer
is usually a small fraction of advertised bandwidth
Example:
• Bandwidth between a host in LA and a host in Tokyo is
45 Mbps, but the actual throughput might be only 5
Mbps.
• That’s just a little over 10% of what you'd have
expected in a world without latency and packet loss

9. • Congestion: when incoming data volume exceeds
networks maximum capacity. The moment the
volume of incoming data exceeds a network's
maximum capacity, congestion occurs.
• Once network congestion gets worse, it can lead
to what is known as a congestive collapse.
• At this stage, throughput is reduced to levels
where useful communication is no longer
possible.

10. • TCP: Transmission Control Protocol or TCP.
– In existence since 1974
– Interwoven into the core fabric of the Internet
– Every time you use email, view web sites, send files,
or administer IT systems remotely, you're most likely
doing it over TCP.
• An old technology with limitations when thrust
into today's communications environment.
• Majority of the protocols in use today, including
FTP, FTPS, SFTP, SCP, HTTP, and HTTPS, still rely on
TCP.

11. Strengths Problems
• Reliable Transmission • Acknowledgement of each
• Flow Control packet transmission
• Acknowledgement times
grow in proportion to the
distance between the
network points involved
with the transfer.

12. • Like TCP, UDP is one of the core protocols of
the Internet.
• But unlike TCP, UDP is not designed to provide
reliability, ordering and data integrity.
• Because UDP is not burdened with
acknowledgements and other processes for
error checking and correction, transmissions
are much faster, but much less reliable.

13. • JSCAPE developed the AFTP protocol--included in
– JSCAPE MFT Server
– AnyClient software.
• Bulk of the data transfers are done on a UDP
channel while other tasks are done on a TCP
channel.
• UDP does not have an acknowledgement process
like TCP--not as affected by latency and packet
loss.

14. Choosing a Solution
• Multiple protocols support
• Platform independent
• Business process automation
• Task simplification
• Security
• Compliance mandate-ready
