A very brief history of AS3

• AS3 was developed by the Internet Engineering Task Force (IETF) to address specific FTP connection problems.

• AS3 is not the successor to AS2 as it offers distinct features

History of AS3

Compare AS3 and FTP

Industry mandates directing the use of one protocol or technology versus another often arise from the history of implementation, industry use, and market penetration. To illustrate, we’ll compare two communications protocols:

  • FTP does not provide receipt confirmation, but provides slight advantages in terms of message size and speed

  • AS3 advances over FTP is in non-repudiation with the use of receipts, or Message Disposition Notifications (MDNs) and digital signatures - a way to verify the receipt and identity
