10GB file transfer

How it works

Ten gigabytes is 80,000 megabits. At 20 Mbps plan about 67 minutes. Link windows follow the slower leg, which is often the recipient.

A 10 GB mezzanine uploads in 13 minutes at 100 Mbps. The client's 25 Mbps download needs about 53 minutes. A link that dies at midnight fails a 23:20 start.

How it differs

Ten gigabytes is a planning figure, not a protocol limit.

Cellular fair-use often throttles halfway and the user blames the file.

Publish byte count and hash together.

On the ticket

• The practical close is a log line: time, actor, byte count, result.
• Without that line the transfer is a story.
• With it, the next person can see whether this door did what the ticket claimed.
• If the path is shared, say so in the partner profile so a later change does not silently pick a different limit, key, or region.
• On a real ticket, write down the door, the byte count, and the clock.
• For ten gb file transfer, that means naming the host or bucket, the expected size, and the time the other side must have a complete file.
• A progress bar is not that record.
• A 200 response that arrives before the complete call is not that record.
• If a retry is allowed, say how many and whether it resumes.
• If a person must approve the send, name the person.
• Partners who receive ten gb file transfer files should match on hash or size before they import.
• A same-length corrupt file passes a size check and fails a hash.
• Keep the published hash off the only channel an attacker can edit, or treat it as a corruption check rather than a substitution check.
• When the path changes, new key, new region, new cap, update the profile the same day so the next run does not use a stale limit.
