Questions and answers

  1. 1. Webinar: Questions and Answers? July 17, 2014
  2. 2. Introduction • John Tkaczewski, President and Co-Founder • Check out our blog: | © Copyright 2 FileCatalyst, 2014
  3. 3. What is File Transfer Acceleration? • File transfer acceleration technology allows large files, or “big data” to be sent quickly 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 and SFTP • Reliability and congestion control is added to UDP at the application layer thus it doesn’t sacrifice its other desirable properties | © Copyright 3 FileCatalyst, 2014
  4. 4. Why is UDP faster than FTP / TCP? 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. | © Copyright 4 FileCatalyst, 2014
  5. 5. How is your UDP different from other UDP based accelerated file transfer ? • Speed – Only vendor that can achieve 10Gbps speeds • File Deltas – Ability to transfer only the changes. Built transparently into the transport • Multi-functional product lines. Single product will provide many functions ex: Data Replication and Web Plug-in are bundled within FileCatalyst Direct. Or Email Distribution and Web based Folder sharing is built-in to FileCatalyst Workflow. • Flexible licensing – either “All inclusive” or “A la carte” , no per seat cost, unlimited client distribution | © Copyright 5 FileCatalyst, 2014
  6. 6. Why do I need Workflow and Direct? • Direct – Point to Point. Includes Desktop App (like Filezilla), HotFolder (Automation), Web applets, CLI and SDK • Workflow - For the web. Web portal for file transfers. Includes: File Submission, Email Distribution, Web based Folder sharing | © Copyright 6 FileCatalyst, 2013
  7. 7. How can you guarantee file delivery? • MD5 checksum – bit by bit comparison is done after transfer • Transfer with temporary file name. Ex: MediaFile123.mxf.fctemp • File Delivery receipt in PDF or XML format (in Workflow only) | © Copyright 7 FileCatalyst, 2013
  8. 8. Can you resume file transfers? • Resume can be done at any block (32MB default) • MD5 checksum – bit by bit comparison is done on the partials before resume operation can be started • File Delta – Rsync can be done on a file that has grown. | © Copyright 8 FileCatalyst, 2013
  9. 9. Are there any limits? • There are no known theoretical limits on the UDP transport. • In production, we transfer single files up-to 8 TB in size • In production, we transfer file sets containing up-to 4 million files • For file transfer speeds, We have a number of 10Gbps production deployments. On the low end, we test with speeds as slow as 128Kbps. • We test and have deployments with up-to 2000 milliseconds (2 seconds!) of latency and 10% pocket loss | © Copyright 9 FileCatalyst, 2013
  10. 10. Tell me about the cloud... • FileCatalyst is an ideal solution to move files in and from the cloud. • All our products have been designed to run on most public clouds: AWS, Azure, OpenStack etc... • Through our cloud partner ComputeNext - we provide SaaS packages. | © Copyright 10 FileCatalyst, 2013
  11. 11. Upcoming Events - ONS 2014 - Off shore North Seas, Stavanger, Norway (Aug 25-28) - IBC 2014, RAI, Amsterdam (September 12-16) And of course don’t forget our monthly webinars... | © Copyright 11 FileCatalyst, 2014
