Same tcp connection used for request and execution of the request?

Hey, my question is:
If I receive a Upload request and the Node starts uploading is the Node using the Same TCP connection as the Upload request was received on or is a new Connection established?
(Sorry it is really hard to Type an english Text with German autocorrect)

as i know it is same port, i have 3-7 conections on same port

Hello @Itsmenh,
Welcome to the forum!
All wording from a customer’s perspective. So, when customer starts upload, your node have an ingress (incoming) traffic.
When customer starts download, your node have an egress (outgoing) traffic.
