The road not taken (was Re: Ungodly packet loss rates)
You're transiting two NAPs (MAE-WEST and the DEC exchange (?)) which both provide service that's essential on one hand (wide access to the greater Internet) and lousy on the other hand (focussed access to a particular site).
This whole thread seems to have taken a wrong turn somewhere, or ignored the fact that this is really goofy routing. Best (TLG) and BBNplanet are both at mae-west, yet velvet.com packets traverse Alternet to get to cisco.com. Cisco also appears to have a direct connection to Alternet which is also at mae-west, yet the packets traverse BBNplanet. I would prefer to think there is an 'Oops' somewhere. I don't know why any provider would purposely do this to their customer's traffic. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

This morning, a message went out to the Cisco population that there was a problem with the circuit to Alternet. This was corrected later this morning. Below is the correct path taken to cisco when everything is loaded correctly. quad:~>traceroute <machine> traceroute to <machine>, 30 hops max, 40 byte packets 1 best-gw-e0.quadrunner.net (205.166.195.1) 6 ms 5 ms 5 ms 2 b00m.best.net (205.149.160.126) 34 ms 34 ms 34 ms 3 core-ether12-1.mv.best.net (205.149.160.65) 41 ms 38 ms 45 ms 4 905.Hssi3-0.GW1.SCL1.ALTER.NET (137.39.133.89) 40 ms 44 ms 38 ms 5 Fddi0-0.CR1.SCL1.Alter.Net (137.39.19.5) 60 ms 39 ms 39 ms 6 Hssi3-0.San-Jose3.CA.Alter.Net (137.39.100.1) 48 ms 43 ms 61 ms 7 Fddi0-0.San-Jose5.CA.Alter.Net (137.39.27.6) 42 ms 41 ms 41 ms 8 cisco-gw.ALTER.NET (137.39.170.110) 40 ms 46 ms 41 ms 9 sj-wall-2.cisco.com (192.31.7.34) 44 ms 61 ms 46 ms ...deleted... /cah
