Agreed - it seems to me they’ve built a medium that signals at the described rate, but didn’t actually send data? I could be misreading. I was looking to find who’s TCP/IP stack got pressed into service, but I guess that’s for a future story.
Edit: this isn’t my area of expertise, but https://news.ycombinator.com/item?id=28674318 https://news.ycombinator.com/item?id=28674318 and the provided link explain why even “Internet” (let alone tcp/ip) might be quite orthogonal to what this technology really is.
- ricardobeat 5y agoUndersea cables carry data using their own framing protocol [1]. Safe to assume this is what they measured for the test. [1] https://en.m.wikipedia.org/wiki/Synchronous_optical_networking https://en.m.wikipedia.org/wiki/Synchronous_optical_networki...
- danellis 5y agoWhat do you mean by "their own"? There's nothing about SONET/SDH that's specific to undersea cables.
- ricardobeat 5y ago"Their own" in opposition to TCP/IP and wires. May not have been the best choice of words.
- maccolgan 5y agoL1 & L2 protocols are not even relevant to TCP/IP and "wires".
- ricardobeat 5y ago[Quite often I'll think twice before commenting on HN due to this type of out of context, knee-jerk retort. It is really not adding to the conversation or helping anyone learn anything new.] SONET has optical networking in its name. It appears to me that data not being transmitted over copper wires is a pretty crucial aspect of it... but really none of this matters as I was simply pointing out that TCP is not relevant to the speed record, in answer to the top two comments above, and not trying to make any absolute assertions about how the transport protocol works. So yes, you're right, I guess?
