They are getting into an area of soft real time systems with a "donkey", in my opinion. Either they are not thinking ahead or are being too optimistic or they are going to use a bunch of hardware to make this work. My thoughts. What do you think?
- londons_explore 9y agoThe realtime-ness of airtraffic control is really very soft... We're comparing to humans on radios here... HTTP is waaaay faster... Also, web services are well understood in terms of scalability, uptime even in the face of replacing/failing hardware, ability to shift load to other datacenters, etc. By building on HTTP, you get authentication (OAuth) and encryption (HTTPS) for free. Build a JSON webservice and you get a nice extensible protocol too, so can add new features on an almost weekly basis without disrupting existing users. By building on TCP/IP, you can allow any form of transport - satellite, wifi, bluetooth, LTE, etc. without any extra testing or certification. Most existing airtraffic control systems wouldn't be able to handle a nuke... The internet is designed to resiliently route around such things...
