In Delphi.NET, Vcl.net has two points that are quite regrettable:
1. You cannot use ADO (DBGO), but according to Levi, this component will be available later.
2. You cannot use the ado.net and BDP, which will be the subject of my article.
In Borland's Delphi communication area, I've seen Danny say, "In Delphi.NET Vcl.net can invoke WinForm components, and WinForm can also invoke vcl.net components."

growth and slow decrease of WindowsBut it has serious RTT unfairness.
The window increase and decrease methods proposed by HSTCP first look at the two formulas in congestion control:
Cwnd = cwnd + a (cwnd)/cwnd ............................ (1)
Cwnd = (1-b (cwnd) * cwnd ............................ (2)
Formula (1) is the window growth mode when congestion is avoided, formula (2) is the window descent mode after packet loss occurs, where a and B are two functions, and cwnd is its independent vari

This is a BDP test in rhca, which is also a very common simulation of latency and packet loss. I will share it with you now.
We also use the application software to test TCP/UDP comparison. When we test the impact of BDP on TCP/IP, we all need some network latency and packet loss simulation, many commercial software can do this. In fact, the perfect Linux itself can use TC to implement this function. the ne
