Can anyone explain to me what congestion exactly is? I am really confused because some people call it as buffer overflow.
PCA -- SW1 -- R1 -- R2 -- SW2 -- PCB -> In this case, how congestion could happen for TCP communication? If PCA has to send data to PCB, PCA will send min(cwnd, rwnd) data. So, I am guessing that buffer overflow cannot happen in both PCA and PCB, but it could happen between SW1 and SW2 if either SW1, R1, R2 or SW2 has smaller buffer size than min(cwnd, rwnd). Plus, just curious how to troubleshoot if PCA keep sending data to PCB using UDP communication and either SW1, R1, R2, or SW2 has smaller buffer size.

Copper Ethernet hosts NICs, on user devices would typically support gig. Server host NICs, might support gig or 10g.
