Transmission Control Protocol carries the vast majority of the data transmitted across both the public Internet and private intranets. Web sessions using HTTP, file transfers, file sharing and system backups typically use TCP. Windows desktop configurations loaded at start-up are TCP based.

However, if your system back-up is to a remote site that is a considerable distance away, you might be using only a small percentage of the bandwidth that you’re paying for. When your security cameras are transferring video to recorders that are remote or are using a wireless connection, the delivery could be slow or interrupted.

There are two primary reasons for poor TCP performance: significant delay (network latency) and network loss. Yes, TCP is designed to retransmit lost data segments, but they will probably be delayed. In the scenario of a long circuit, the resulting higher delay tells TCP that it must limit its rate of transmission so it won’t overwhelming the receiver’s buffer.
