Request to rename Content Size Policy to Network Policy about transfer-size

[igrigorik]

We did discuss the use case of limiting number of consumed bytes — e.g. at most X KB of Javascript — regardless of where they come from (cache or network), which is why we went with "content size".. I'm OK with excluding that use case if we think it's orthogonal and better tackled elsewhere, but want to make sure that we're all on the same page. If memory serves, I think Ojan was interested in this angle.

If we do scope it down.. "Network Policy" is very broad, which may be a good thing, if we want to expand what it controls in the future? Alternatively, perhaps "download policy" is closer to what we're tackling here?

@ojanvafai and I discussed this yesterday, he was on board.

I could imagine having a max upload and max download in the end, but starting with max download. What other network policies can we imagine that might fit in here in the future? All resources must use QUIC? Only allow the given certificate?

[igrigorik]

FWIW, QUIC is not policy material.. I doubt you want pages to fail if UDP can't go through. Certificates are already handled by pinning, and not something we should venture into here?

Upload is more interesting and I can see some rationale for that. Although, arguably the user is in control there.. unless the site is doing some malicious, so perhaps that's redundant? I'm a bit worried by "Network" being too broad.

Network Usage Policy?
Network Size Policy?

It might be useful to have the broader name. It's unclear to me. We should get feedback from @ojanvafai and others.

[ojanvafai]

It's unclear to me too. I don't feel strongly.

Another alternative would be DataSizePolicy to match the Save-Data header.

NetworkDataSizePolicy? /me ducks :)

[igrigorik]

Transfer Size Policy? We expose transferSize as part of Resource Timing API, which maps directly what we're discussing here.. I think: https://www.w3.org/TR/resource-timing-2/#dom-performanceresourcetiming-transfersize

[ojanvafai]

Seems fine to me.

TSP works for me as well.
