  3. 3. TCP Overview • Provides reliability, error checking, ordered packets in a stream • Congestion control built in • Internet could not survive without it • Works well for most internet traffic, email, web browsing small ad-hoc transfers | © Copyright 3 FileCatalyst, 2013
  4. 4. File Transfer Issues with TCP • Flow control limits transmission window, causes dead air with high latency • Very aggressive in response to network congestion, cannot tune in application layer • Result is less than ideal performance on wireless, satellite, or long haul links • Can be tuned but still not ideal for many-one, one-many Data Packet | © Copyright 4 FileCatalyst, 2013 TCP is a very serial process. Each packet of data must be received before a new packet is sent = Decreased transfer speed Source File Destination File Acknowledgments
  5. 5. Acceleration with FileCatalyst • Ideal for bulk file transfer • Predictable - Can send at a perfect rate • Not affected by latency or packet loss • Congestion Control implemented in application layer • Tunable congestion control aggression • Instantly detect link capacity Source File | © Copyright 5 FileCatalyst, 2013 Destination File Acknowledgments FileCatalyst completely saturates the pipe by sending multiple blocks of data = Increased transfer speed

  8. 8. UDP File Transfer Considerations • Plays fair with other traffic on network • 10 Gbps file transfer, single stream • High performance for many small files • Security, reliability, automatic resume • Automation tools, SDK, central management | © Copyright 8 FileCatalyst, 2013
  9. 9. The FileCatalyst Solution • Thousands of customers from all verticals • Support for cloud deployments on Amazon, Azure, etc. • Integration partner program, with integration support team • Found by independent study to be only solution to maintain 10 Gbps with high latency and packet loss • More info visit filecatalyst.com, Twitter @filecatalyst, LinkedIn, Google+ | © Copyright 9 FileCatalyst, 2013
