How to filter nodes?

waiaw · March 9, 2022, 5:20am

I am a newbie to ipfs. Please correct me if I am wrong.

When ipfs download a file, it will randomly select a node that contains the file.
I want to ensure that the download speed is at least a certain level.

so what i want to do is:
If a slow node is selected, switch to other nodes.
how can I config this?

No need. IPFS will request the block from several nodes that have the block and take the first one to reply. I’m not aware of a way to configure the number of nodes contacted and I don’t recall what that number is.

**Abstract**

Bitswap is the data trading module for IPFS. Its purpose is to request blocks from and send blocks to other peers in the network. Bitswap has two primary jobs:
1. Attempt to acquire blocks from the network that have been requested by the client.
2. Judiciously (though strategically) send blocks in its possession to other peers who want them.
