Tool/software:
Now we are using the TCP prtocol provided by TDA2x.
Now TDA2x is TCP server
We met two strange issues. These two kinds of issue occured by accident.
1. When TCP client send SYN at TCP connection initilization stage, Server deos not response with SYN/ACK immediately.
2 ACK delay will be 1 second. Considering our test evnironment is based on cable, this delay value is too big.
Can you help to answer our questions?
Thank you in advance.
Hello, thank you for respose. Now totally we meet two kinds of issue.
Below is the first one. Please have a look of below picture.
In this picture, 172.30.1.200 is a TCP client. TDA2x works as a TCP server and its ip address is 172.30.1.11.
When TCP client want to establish a TCP connection between client/server, it will send out a SYN to Server. And in normal case, TDA2x should response with a SYN/ACK. But from upper picture, we can see TDA2x dd not response anything.
Below is the second issue. Again,TDA2x works as a TCP server again.
Please pay attention to Line #10116. Here TCP client send the data to server, ACK=353 and SEQ =225.
Server is expected to response with ACK=225 immediately. But actually not. After around 1 second. server response with a TCP keep-Alive.
This is not correct.
Can you help us to resolve these two issues? Thank you very much.
