How do multiple nodes average use of traffic?

admin

I have 20 different IP American nodes, but each node can only use 5 GB.
I want to download a file of 100 GB, is there any way that I can use these 20 nodes to download it so as to achieve the following effects:
1. To always be connected to the target website and not lose connection in the middle
2. The 20 nodes should consume 5 GB on average
3. Software automatically switch to each node without needing me to manually switch
Is there such a win client for V2RayN?
