Acceleration Technology: Solving File Transfer Issues
Download as PPTX, PDF1 like931 views
File transfer acceleration can significantly increase file transfer speeds compared to traditional methods like FTP. It works by transferring files over UDP instead of TCP, avoiding issues from network latency and packet loss that slow TCP transfers. This allows files to be sent at full network speed even over long distances or unreliable links. As a result, file transfer acceleration can reduce costs from unused bandwidth and boost productivity by speeding file sharing and project completion.

- 3. Traditional File Transfer Methods & Issues Method Associated Issues FTP Server Solution •Slow file transfer speeds •Learning curve for end-users •Users may not be able to connect to the FTP server if IT networks do not allow unrestricted FTP access •Difficult maintenance for FTP administrators managing end users and providing support to the FTP server Email File Attachments •Attachment file size limitations (usually of 10 MB or less) cause emails with files exceeding this limit to bounce back •Attached files add to the storage requirements of a mail server when emails are archived, increasing archival costs •Email uses SMTP for transfers, not the most efficient protocol for transferring large files over the Internet 3 | © Copyright FileCatalyst, 2013
- 4. Traditional File Transfer Methods & Issues Method Associated Issues Instant Messaging •File transfers are not usually possible between different IM clients •Transfers are not usually over secure channel, increasing the chances for data leaks •No file tracking capabilities when transferring files over IM makes it difficult to ensure delivery of files •Poor network utilization (usually files are transferred over the TCP/IP protocol cause slow transfers Physical Media •Preparation time from recording the data to printing out mailing labels, to shipping physical media makes for a less efficient delivery process •Costs of the physical media and courier services can easily add up •Delivery time of shipping physical media can take anywhere from 1 to 5 days, not including unexpected delays 4 | © Copyright FileCatalyst, 2013
- 5. What is File Transfer Acceleration? • File transfer acceleration technology allows large files, or “big data” to be sent quick and in many cases over large geographical distances without being impeded by network impairments such as latency and packet loss • This is accomplished by transferring files using the UDP protocol instead of the TCP protocol, the protocol used for FTP • The main difference between UDP and TCP is that UDP wastes no time communicating about the receipt of a block of data so that regardless of network latency, data transmission remains constant, thus overcoming the peak and valley effect that occurs with TCP based protocols on links with high latency • Application layer protocol can be added to UDP to add a layer of reliability and rate control while not sacrificing its the other desirable properties 5 | © Copyright FileCatalyst, 2013
- 6. File Transfer Acceleration Benefits • Full Line Speed Utilization: Other methods of file transfer using TCP (i.e. FTP) have built-in practical speed restrictions and do not make full use of a user’s line speed. At lower speeds it may not be noticed if there is a 4Mbps max speed, however as base connection speed increases, the more acceleration is needed to make full use of an investment in line speed. • Geographic Diversity: As distance between to transfer points or using a satellite connection, transfers, especially of large files, will slow dramatically. While TCP performance takes a dramatic hit with latency, file transfer acceleration technology is immune to it. 6 | © Copyright FileCatalyst, 2013
- 7. File Transfer Acceleration Benefits • Reliable Transfers: Connections such as satellite links are prone to packet loss. With TCP, dropped packets cause the throughput to be reduced dramatically as a response to “unreliability”. However, acceleration technology brushes it off, resends the dropped packets, and continues at full speed. 7 | © Copyright FileCatalyst, 2013

- 9. Costs of Slow File Transfers • Most enterprises do not realize the cost of slow file transfers. The most significant hard costs is bandwidth; soft costs include lost hours in terms of employee productivity and project completion • Acceleration technologies provide return on investment by maximizing existing infrastructures. Spending money on more bandwidth makes little sense if current bandwidth is underutilized. 9 | © Copyright FileCatalyst, 2013
- 10. Costs of Slow File Transfers • Based on the following chart, consider some scenarios in which acceleration provides cost or productivity benefits: 7Mbps – 10 Mbps Average monthly cost 25- 30Mbps 50 -60Mbps 150+ Mbps $50 $65 $105 $200 *Based on average costs for business grade Internet connections, 2013 10 | © Copyright FileCatalyst, 2013
