The problem that I am having is that there is this company that transfers data from one city to another for us. This data is rather critical and sesitive in nature. We have been having problems with the transfers using TCP/IP so this company is considering sending the data by UDP (this will as before be sent through the internet, not a vpn) my concern is that, from what I understand is that UDP is conectionless so if you loss a packet it is gone forever, and there is no way to guarantee a complete transmition or data integrity. So I was wondering if this company was going to try and combine UDP with TCP for the conectability and transmition integrity. Make sense to you? If you have any ideas or info about this it would be great I appreciate any respones, Thanks
