Lack of data integrity checks

Lack of data integrity checks

I'm unclear on what corruptions you're concerned about. When people say "end to end," they're pointing to the fact that something could get corrupted before or after some other integrity check is done. Are you saying there's a significant risk that the data gets corrupted inside a router (outside of Ethernet integrity checks) or inside the client or server network stack (outside of UDP integrity checks)? Are we talking about OS bugs?

Just wondering, because while all kinds of failures are possible, it wouldn't make sense to protect against some risk that we routinely accept in other areas.

You also mention the UDP checksum as simply being too weak. If that's the problem, then I would just refer to "additional integrity checks" rather than emphasize "end to end."
