A problem when the cable reconnect in Redundant LAN connections

Hi,everyone

I got two computers A and B, each with two NICs and each NIC is assigned a static IP:

A: 172.17.47.2/255.255.255.0    172.17.63.2/255.255.255.0

B:172.17.47.4/255.255.255.0    172.17.63.4/255.255.255.0

Both A and B are connected to a Switch by two cables

 

 

 

I create a DataWriter publishing data every 200 milliseconds on A , a DataReader subscribing data on B, everything  goes well, then I disconnect the cable with IP 172.17.47.4 on B, the transmission did not break off. After a while, I plugged that cable,something strange happed: the DataWriter seemed to slow down sending rate, and sent a sample about every 3 seconds, this state will keep 10~20 seconds, then return to normal.the QoS of DataWriter and DataReader are default.

I wonder:

Why the DataWriter get stuck for a while when the cable is connected again?

Can I solve the problem by configuring QoS, and how?

 

Thanks very much!
