Can anyone tell me how does network duplication occur in the internet and how frequent does network duplication occur ? Does network duplication of packets occur during handoff from one wireless cell to another, or some dysfunctional routers duplicating the packets,etc. Thank you. cheers, Kwang Mien From owner-tcp-impl@grc.nasa.gov Fri Jan 4 02:30:56 2002 Received: from seraph3.grc.nasa.gov (firewall-user@seraph3.lerc.nasa.gov [128.156.10.12]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id CAA28750 for ; Fri, 4 Jan 2002 02:30:55 -0500 (EST) Received: by seraph3.grc.nasa.gov (Postfix, from userid 5) id 82C6D64150; Fri, 4 Jan 2002 02:29:24 -0500 (EST) Received: from lombok-fi.lerc.nasa.gov(139.88.112.33) by seraph3.grc.nasa.gov via csmap (V6.0) id srcAAA8vaGMp; Fri, 4 Jan 02 02:29:24 -0500 Received: (from listserv@localhost) by lombok-fi.lerc.nasa.gov (NASA LeRC 8.9.1.1/8.9.1) id CAA10818 for tcp-impl-outgoing; Fri, 4 Jan 2002 02:16:49 -0500 (EST) Received: from acs-viruswall.grc.nasa.gov (acs-viruswall.lerc.nasa.gov [139.88.112.21]) by lombok-fi.lerc.nasa.gov (NASA LeRC 8.9.1.1/8.9.1) with ESMTP id CAA10814 for ; Fri, 4 Jan 2002 02:16:48 -0500 (EST) Received: from seraph2.grc.nasa.gov (localhost [127.0.0.1]) by acs-viruswall.grc.nasa.gov (NASA LeRC 8.9.1.1/8.11.x) with ESMTP id CAA26785 for ; Fri, 4 Jan 2002 02:16:47 -0500 (EST) Received: by seraph2.grc.nasa.gov (Postfix, from userid 5) id 61500C6900; Fri, 4 Jan 2002 02:16:47 -0500 (EST) Received: from sparkle.rodents.montreal.qc.ca(216.46.5.7) by seraph2.grc.nasa.gov via csmap (V6.0) id srcAAAVBaWRY; Fri, 4 Jan 02 02:16:38 -0500 Received: (from mouse@localhost) by Sparkle.Rodents.Montreal.QC.CA (8.8.8/8.8.8) id CAA02661; Fri, 4 Jan 2002 02:16:35 -0500 (EST) Date: Fri, 4 Jan 2002 02:16:35 -0500 (EST) From: der Mouse Message-Id: <200201040716.CAA02661@Sparkle.Rodents.Montreal.QC.CA> Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit To: tcp-impl@grc.nasa.gov Subject: Re: Network Duplication In-Reply-To: <4.3.2.7.2.20020104143110.00c73910@postman.cwc.nus.edu.sg> References: <200112111921.fBBJLeQ00986@maggie.ka9q.net> <200112111658.fBBGwd000600@restless.weston.bsdi.com> <200112111658.fBBGwd000600@restless.weston.bsdi.com> <4.3.2.7.2.20020104143110.00c73910@postman.cwc.nus.edu.sg> Sender: owner-tcp-impl@grc.nasa.gov Precedence: bulk Content-Transfer-Encoding: 8bit > Can anyone tell me how does network duplication occur in the internet I've seen it occur under circumstances that make me suspect flaky MAC address filtering in Ethernet hardware: Machine A, MAC address MA, sends through gateway G, MAC address MG. Machine C, MAC address MC, is on the same (non-switched) segment S as A and G. Two copies of the packet come out the far side of G. Sniffing on S sees two copes, each addressed to MG, one with MA as source and one with MC as source. The most plausible explanation that occurs to me is that C's hardware incorrectly received the packet and C's kernel then "forwarded" it to G (which was the correct next hop for that packet, for A and C both). This could also occur if the hardware is running promiscuous but the kernel isn't filtering out packets that aren't for it before handing stuff to the protocol stack (either because its kernel isn't smart enough or because it thinks the harware isn't promiscuous and hence that the check is unnecessary). Unfortunately I didn't think to check at the time whether the TTL in the copy from MC was one lower than the TTL in the copy from MA. I have also seen very long delay times, on the order of several seconds; a long-delayed packet can "duplicate" its retransmission. But from the rest of your question, I suspect you aren't particularly interested in this case. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse@rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From owner-tcp-impl@grc.nasa.gov Sun Jan 6 08:41:56 2002 Received: from seraph3.grc.nasa.gov (firewall-user@seraph3.lerc.nasa.gov [128.156.10.12]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id IAA23381 for ; Sun, 6 Jan 2002 08:41:55 -0500 (EST) Received: by seraph3.grc.nasa.gov (Postfix, from userid 5) id AD56464164; Sun, 6 Jan 2002 08:41:07 -0500 (EST) Received: from lombok-fi.lerc.nasa.gov(139.88.112.33) by seraph3.grc.nasa.gov via csmap (V6.0) id srcAAAd9aaKV; Sun, 6 Jan 02 08:41:07 -0500 Received: (from listserv@localhost) by lombok-fi.lerc.nasa.gov (NASA LeRC 8.9.1.1/8.9.1) id IAA27026 for tcp-impl-outgoing; Sun, 6 Jan 2002 08:22:24 -0500 (EST) Received: from acs-viruswall.grc.nasa.gov (acs-viruswall.lerc.nasa.gov [139.88.112.21]) by lombok-fi.lerc.nasa.gov (NASA LeRC 8.9.1.1/8.9.1) with ESMTP id IAA27018; Sun, 6 Jan 2002 08:22:22 -0500 (EST) Received: from seraph2.grc.nasa.gov (localhost [127.0.0.1]) by acs-viruswall.grc.nasa.gov (NASA LeRC 8.9.1.1/8.11.x) with ESMTP id IAA08252; Sun, 6 Jan 2002 08:22:21 -0500 (EST) Received: by seraph2.grc.nasa.gov (Postfix, from userid 5) id A8279C68DF; Sun, 6 Jan 2002 08:22:09 -0500 (EST) Received: from smtp.dave.sonera.fi(131.177.130.21) by seraph2.grc.nasa.gov via csmap (V6.0) id srcAAAsgaauL; Sun, 6 Jan 02 08:22:09 -0500 Received: from gurtoan1-nb.etela.sonera.fi ([131.177.36.107]:2184 "HELO gurtoan1nb") by inside.dave.sonera.fi with SMTP id ; Sun, 6 Jan 2002 15:21:51 +0200 Message-ID: <03be01c196b5$15aa16c0$6b24b183@etela.sonera.fi> From: "Andrei Gurtov" To: "Noritoshi Demizu" , , References: <200112111658.fBBGwd000600@restless.weston.bsdi.com> <20011227175859X.demizu@dd.iij4u.or.jp> Subject: Re: Doubt regarding the MANAGING THE RTO TIMER Date: Sun, 6 Jan 2002 15:21:43 +0200 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2600.0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2600.0000 Sender: owner-tcp-impl@grc.nasa.gov Precedence: bulk Content-Transfer-Encoding: 7bit Noritoshi- I agree with you. According to a comment on Steven's page this fix is used by all modern TCPs. Do you happen to have some experimental data that show RFC1323-like and fixed behavior? In addtion to inflating RTO value, echoing old timestamps can cause problems to the Eifel algorithm. According to Pasi Sarolahti, Linux follows RFC1323 that lets Eifel to incorrectly conclude a spurious timeout in a scenario with lost packets and ACKs.

I have implemented the features listed in "WAP Wireless Profiled TCP (WAP-225-TCP)" and , including TCP timestamps options, for the TCP/IP stack of ACCESS (www.access.co.jp) which I am working for. During the test period, I found the problem. I tried to reproduce the phenomena today. Here are two traces at the receivers side. Both the sender and the receiver are ACCESS's stacks. The RTT is approximately 50ms. The timestamp counts up every 500ms. ------------------------------------------------------------------------- When both the sender and the receiver follow RFC1323: i.e. SEG.SEQ <= Last.ACK.sent < SEG.SEQ + SEG.LEN Scenario: - Packet (1) triggers Fast Retransmit(2) at the sender. - The receiver sent an ACK(3) for data(2), but the ACK was dropped. - The sender retransmitted data twice, but they both were dropped. - The receiver sent an ACK(5) for data(4), and the ACK arrived at the sender. - The sender sent new data(6). The recever sent an ACK(7). See the timestamp echo value of ACK(5). Because this is the first ACK of 66609 for the sender, the sender calculates RTT with this very old value. The calculated RTT might be about 10sec (= (36 - 15) * 500ms). Too big...

The receiver sent an ACK(3), but dropped. - The sender sent data(4)&(5). The receiver sent an ACK(6), but dropped. - The sender retransmitted data(7), the same data as data(1). - The receiver sent an ACK(8) with correct timestamp echo value. - The sender sent new data(9). The recever sent an ACK(10). See the timestamp echo value of ACK(8). Because this is the first ACK of 215753 for the sender, the sender calculates RTT with this value. The calculated RTT might be about 500ms (= (26 - 25) * 500ms). Not bad.

LOCATION:Crete: - Crete is a Unique Place in the World: In this magic
island, so richly endowed by Nature and History, everything is in
abundance: blond beaches with palm-trees, cool gorges, serene
coves, palm-forests, mysterious caves, minoan palaces,
paleochristian churches, byzantine churches, Islamic mosques, and
of course modern cosmopolitan life. Crete lies in the crossroads of
the three ancient continents: Europe-Asia-Africa and the Cretan
Civilization borrowed elements from European, asian and african
world. Also, Crete, in the minoan era, gave birth to the first
civilization in the west-european sense. Here, Zeus, the father and
king of ancient greek Gods was born. Many famous Artists and
Politicians like El-Greco, Venizelos, Kazantzakis and Kornaros were
born in Crete.

First of all, why we need TCP soft errors? Let us consider a TCP connection is in ESTABLISHED state. If we pulled out cable OR disable/delete IP Interface, then the ifnet/destination is not reachable. There may be so many reasons for TCP returning an error before TIME OUT. - routing loops - some intermediate routers are down - unreliable, non-fault tolerant best effort lower layers etc etc ... Application can still send data on those sockets but TCP/IP stack can not send out any message (rather accumulating all the TCP messages expecting that link or route to reach the destination might come back up) If the system is low in memory or a crazy applications/soft state protocol is sending thousands of messages per second, then, all mbufs will get used up in the system very fast (before TCP connection Times Out). 1. soft errors are recorded if tcp_output (intern ip_output) returns EHOSTUNREACH etc errors. If connection is in ESTABLISHED then it will be ignored by some implementations. Don't know why? 2. Is there any way to suppress these soft errors and consider them as real errors (before clogging all the buffers in the system)?
