When the ICA protocol was commercially launched (1991), it did not even support TCP until an engineer named Jeff Muir decided to give it a try in 1994 (make sure you read his blog post about it it’s a fascinating journey back in time). If you are ~40 or older, then you know that TCP wasn’t always king. In fact, TCP only started to take off when ARPANET (the precursor to the modern internet) switched to TCP/IP in 1983 (replacing the earlier NCP protocol). TCP: de facto transport protocol of the internet We always like to start with a little bit of history, because it is essential to understanding the present. In the XenApp & XenDesktop 7.16, HDX Adaptive Transport is set to “preferred,” by default, so receivers will use EDT whenever possible. Therefore, we want to give you a thorough background on the enhancements. We will clear up misconceptions around EDT and explain what are we doing, why we are doing it, and where are we headed.
The members of the Citrix HDX team, have been wanting to write a blog post about HDX Adaptive Transport and Enlightened Data Transport (EDT) ICA (HDX) is the Citrix main protocol and these are some of its biggest improvements ever.
