I want to keep overheads low for the application, so currently I am using UDP on port 60. The sending of the message occurs in a seperate thread. It works! However I am not sure what protocol should I use. UDP or HTTP? What port should I use? However I have discovered that many networks do not let traffic out on UDP port 60 so the messages never arrive. So should I use HTTP on port 80? /Richard Back to top Martin James Guest Posted: Fri Sep 29, 2006 8:11 am    Post subject: Re: Message sending Quote: However I have discovered that many networks do not let traffic out on UDP port 60 so the messages never arrive. Yes - many routers/firewalls/antiVirus can cause problems. Quote: So should I use HTTP on port 80? That is my favorite - nearly always works.

It is basically used for direct connections to and from a TCP server. TCP also guarantees that each data packet will reach it's destination whereas UDP does not. UDP is good for broadcasting data - IE realmedia, sound etc, but is not generally good for control communications etc. For what you are building, it sounds like TCP is much more what you need to be using. UDP is kind of like analogue radio. It is broadcasted, but receiving it can be somewhat hard. TCP is similar to digital/morse code. You receive it because the receiver differentiates between 0's and 1's making errors or confusion extremely unlikely. TCP is also a slower protocol. It's time and resource consuming because of it's complexity and processing requirements. UDP on the other hand doesn't need a lot of resources as it basically just broadcasts without caring about the end result. I don't know what components you are using for your current UDP, but you should look into Indy sockets or ICS (I think it's called). Indy is very good but can be rather hard to get installed at the moment because the latest version is also the live version - meaning that the team work on the very same files downloaded from the server. Remy would probably have a much better and precise explanation than me.... Jamie.
