A concise, readable and accurate discussion on why TCP/IP works so reliably can be found at http://www.myreadingroom.co.in/notes-and-studymaterial/68-dcn/853-error-control-in-tcp.html. I quote "TCP provides reliability using error control. Error control includes mechanisms for detecting corrupted segments, lost segments, out-of-order segments, and duplicated segments. Error control also includes a mechanism for correcting errors after they are detected. Error detection and correction in TCP is achieved through the use of three simple tools: checksum, acknowledgment, and time-out." The thing is, the higher-order CAT-X cables are physically built from a shielding and twisted-pair density factor to carry higher frequencies more reliably. Meaning more bits/sec down the line. If you try to shove 10GHz data down a CAT3 cable nothing will arrive reliably at the other end because the cable is not built to carry those frequencies. In a normal house, CAT5e or CAT6 is enough for Gigabit ethernet at the kind of cable lengths one normally finds at home. Error correction in TCP/IP s not guesswork. It's either retransmission or mathematical reconstruction. If you know that 3 + 5 + X = 9 then you don't guess the value of X, you calculate it to be 1. This is the biggest mistake Audiophiles make - they assume corrupt data has to be guessed when it is simply either re-sent down the line or else calculated based on the checksums sent together with the real data. It was the same crap when the CD came out and Audiophiles worried that CD players had to guess values for the 1s and 0s lost to scratches - in reality they were mathematically reconstructed with FULL accuracy. Period. That's why any claims about ethernet cables/switches/routers are total b****x when it comes to audio data transcending them :cool: ------------------------------------------------------------------------ philchillbill's Profile: http://forums.slimdevices.com/member.php?userid=68920 View this thread: http://forums.slimdevices.com/showthread.php?t=114088 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
