Vint Cerf on Internet Challenges

chamilto0516 writes "Phil Windley, a nationally recognized expert in using information technology, drove up to the Univ. of Utah recently hear this years Organick Lecture by Vint Cerf, one of the inventors of the Internet. In his notes, Vint talks about, 'Where is the Science in CS?' He also goes on to talk about real potential trouble spots with the Internet, but there is a bit on Interplanetary Internet (IPN). Apparently, the flow control mechanism of TCP doesn't work well when the latency goes to 40 minutes."

TCP at 40 mins...

[Anonymous Coward]

That is a easy problem to solve... Just set the TCP windows size VERY large.

Interplanetary TCP??

Apparently, the flow control mechanism of TCP doesn't work well when the latency goes to 40 minutes.

Well... Duh!

I just assumed everyone ~knew~ we'd be using UDP between planets...

Sheesh... do I have to send a memo about ~everything???

Vint Cerf?

[Anonymous Coward]

It's a person? I thought it was a number at first.

Come on here...

That's what subspace communication is for. I would hope that a geek of his caliber has at least watched some Star Trek.

Re:What?

Vint Cerf co-authored TCP/IP. You just used it to post.

Vent Cerf = 1
AC = 0

Re:Latency over lightyears...

[14erCleaner]

That sounds like a hardware problem to me. Therefore, most computer scientists will ignore it.

Nationally Recognized Expert

[tyler_larson]

Phil Windley, a nationally recognized expert in using information technology...

Wow. If I had known that he was such a celebrity, I probably would have paid more attention in his Enterprise Systems class at BYU.

I guess it's nice to learn from someone important who doesn't act like the world revolves around him.

Latency

Apparently, the flow control mechanism of TCP doesn't work well when the latency goes to 40 minutes.

...as any DirecWay customer can readily attest to...

Re:What?

[Usquebaugh]

Bonus points for telling us where he pinched the idea from?

Re:Especially for telemetry data

[Linker3000]

If the data's that important we could always create a multi-part ZIP or RAR file and send it via email - those blighters can sometimes take days to arrive with no apparent ill effect!

Well... He was working at the patent office and there was this....

Oh, wait, that was a German Physicist....

Long Ping Times.

Apparently, the flow control mechanism of TCP doesn't work well when the latency goes to 40 minutes.

That's strange. I thought that issue would have been worked out by RFC 1149 or CPIP. You would think that 40 minute transit times would be a quick ping when using the Carrier Pigeon Internet Protocol [linux.no] (CPIP).
