Obviously some applications care. In addition to the examples mentioned earlier: out of order packets aren't really good for TCP header compression, so they will slow down data transfers over slow links.
How about ACK? I think that's the point that Richard was making... even with SACK, out-of-order packets can be an issue.
But how is packet reordering on two parallell gigabit interfaces ever going to translate into reordered packets for individual streams? Packets
Queue depths. Varying paths. IIRC, 802.3ad DOES NOT allow round robin distribution; it uses hashes. Sure, hashed distribution isn't perfect. But it's better than "perfect" distribution with added latency and/or retransmits out the wazoo.
for streams that are subject to header compression or for voice over IP or even Mbone are nearly always transmitted at relatively large intervals, so they can't travel down parallell paths simultaneously.
What MTU? Compare to jitter multiplied by line rate. -- Eddy Brotsman & Dreger, Inc. - EverQuick Internet Division Phone: +1 (316) 794-8922 Wichita/(Inter)national Phone: +1 (785) 865-5885 Lawrence ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Date: Mon, 21 May 2001 11:23:58 +0000 (GMT) From: A Trap <blacklist@brics.com> To: blacklist@brics.com Subject: Please ignore this portion of my mail signature.
