In MPLS network when we speak of utilization is 50% between 2 points in a circuit , What does it mean and how can I measure it ?

I think too. Btw as i said, have host on tinet, and it is 100% clear from EC2. So seems tinet is fine for sure.

I thought Verizon had better things to do that plan any kind of upgrades or changes to something that everyone thought they consider dead anyways. C.

30% packet loss between cox.net and hetzner.de, possibly at tinet.net
by Constantine A. Murenin 06 Apr '13

06 Apr '13

Hello, There has been at least a 25% packet loss between hetzner.de and cox.net in the last couple of hours. Tried contacting hetzner.de, but they said it's not on their network. This has already happened a couple of days ago, too (strangely, on April 1), but then was good for the rest of the week -- no problems whatsoever. I wouldn't really care about this, if not for ssh: it just doesn't work on such huge loss. No other routes or networks seem affected. Any advice? # mtr --report{,-wide,-cycles=60} --order "SRL BGAWV" ip68-97-XX-XXX.ok.ok.cox.net ; date HOST: xxxxxxxxxx Snt Rcv Loss% Best Gmean Avg Wrst StDev 1.|-- static.33.203.4.46.clients.your-server.de 60 60 0.0% 0.5 1.1 1.5 3.8 1.1 2.|-- hos-tr3.juniper2.rz13.hetzner.de 60 60 0.0% 0.2 0.4 3.4 46.2 9.8 3.|-- hos-bb2.juniper4.rz2.hetzner.de 60 60 0.0% 2.7 3.0 3.6 38.1 4.8 4.|-- r1nue1.core.init7.net 60 60 0.0% 2.8 4.9 6.0 13.3 3.9 5.|-- r1nue2.core.init7.net 60 60 0.0% 2.9 3.9 4.6 13.8 3.1 6.|-- r1fra2.core.init7.net 60 60 0.0% 5.7 7.6 8.2 17.3 3.8 7.|-- r1fra1.core.init7.net 60 60 0.0% 5.9 8.2 8.9 17.1 3.9 8.|-- xe-4-2-2.fra23.ip4.tinet.net 60 60 0.0% 5.9 6.4 7.1 38.2 5.2 9.|-- xe-3-0-0.dal33.ip4.tinet.net 60 39 35.0% 165.8 169.7 170.1 226.3 13.1 10.|-- cox-communications-gw.ip4.tinet.net 60 47 21.7% 159.0 162.3 162.6 207.9 10.4 11.|-- mtc3dsrj01-ae1.0.rd.ok.cox.net 60 46 23.3% 163.1 166.1 166.3 196.3 8.0 12.|-- 68.12.14.1 60 49 18.3% 161.3 161.6 161.6 161.9 0.1 13.|-- COX-68-12-10-114-static.coxinet.net 60 40 33.3% 162.5 162.8 162.8 163.1 0.1 14.|-- COX-68-12-10-114-static.coxinet.net 60 44 26.7% 162.5 162.8 162.8 163.2 0.1 15.|-- ip68-97-XX-XXX.ok.ok.cox.net 60 43 28.3% 170.9 173.5 173.5 179.5 1.5 Fri Apr 5 16:21:56 PDT 2013 % mtr --report{,-wide,-cycles=60} --order "SRL BGAWV" static.88-198-xx-xx.clients.your-server.de ; date HOST: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Snt Rcv Loss% Best Gmean Avg Wrst StDev 1.|-- 192.168.xxxx 60 60 0.0% 1.0 1.9 2.5 14.0 2.5 2.|-- 10.0.x.x 60 60 0.0% 1.3 2.3 2.6 7.6 1.6 3.|-- 10.6.0.1 60 60 0.0% 8.9 13.7 14.3 38.6 5.1 4.|-- COX-68-12-10-113-static.coxinet.net 60 60 0.0% 9.6 14.1 15.6 97.2 11.9 5.|-- COX-68-12-10-2-static.coxinet.net 60 60 0.0% 10.1 14.9 15.4 31.2 4.3 6.|-- 68.1.5.161 60 60 0.0% 55.8 61.8 62.1 93.1 6.6 7.|-- nyk-s2-rou-1001.US.eurorings.net 60 60 0.0% 55.7 63.6 64.8 162.4 16.7 8.|-- nntr-s1-rou-1101.FR.eurorings.net 60 60 0.0% 149.5 168.7 169.7 213.1 19.3 9.|-- kehl-s2-rou-1103.DE.eurorings.net 60 47 21.7% 147.2 151.6 151.6 161.6 3.3 10.|-- ffm-s1-rou-1102.DE.eurorings.net 60 60 0.0% 144.1 148.9 149.1 174.2 6.4 11.|-- nbg-s1-rou-1001.DE.eurorings.net 60 60 0.0% 147.1 156.2 157.3 290.9 22.4 12.|-- kpn-gw.hetzner.de 60 48 20.0% 173.8 178.9 179.0 198.2 5.1 13.|-- hos-bb2.juniper2.rz13.hetzner.de 60 43 28.3% 173.4 179.6 179.9 230.1 11.8 14.|-- hos-tr4.ex3k11.rz13.hetzner.de 60 48 20.0% 176.9 181.9 181.9 198.9 4.4 15.|-- static.88-198-xx-xx.clients.your-server.de 60 37 38.3% 173.2 177.0 177.0 186.6 3.4 Fri 5 Apr 2013 16:22:51 PDT The huge packet loss even extends to the regular cox.net web-site, it seems: # mtr --report{,-wide,-cycles=60} --order "SRL BGAWV" cox.net ; date HOST: xxxxxxxxxx Snt Rcv Loss% Best Gmean Avg Wrst StDev 1.|-- static.33.203.4.46.clients.your-server.de 60 60 0.0% 0.5 1.2 1.7 5.6 1.4 2.|-- hos-tr1.juniper1.rz13.hetzner.de 60 60 0.0% 0.2 0.3 2.1 29.3 6.0 3.|-- hos-bb2.juniper4.rz2.hetzner.de 60 60 0.0% 2.7 3.5 5.8 62.5 10.1 4.|-- r1nue1.core.init7.net 60 60 0.0% 2.8 4.2 5.2 13.5 3.8 5.|-- r1nue2.core.init7.net 60 60 0.0% 2.9 4.7 6.0 28.7 5.0 6.|-- r1fra2.core.init7.net 60 60 0.0% 5.7 7.4 8.1 15.9 3.6 7.|-- r1fra1.core.init7.net 60 60 0.0% 5.9 7.6 8.1 16.8 3.2 8.|-- xe-4-2-2.fra23.ip4.tinet.net 60 60 0.0% 5.9 6.4 7.1 36.2 5.6 9.|-- xe-9-0-0.was14.ip4.tinet.net 60 43 28.3% 142.3 145.0 145.2 190.0 9.6 10.|-- cox-communications-gw.ip4.tinet.net 60 48 20.0% 124.8 129.6 130.2 176.6 13.2 11.|-- dukedsrj02-ge210.0.rd.at.cox.net 60 45 25.0% 137.7 141.2 141.6 194.7 11.6 12.|-- 68.1.15.238 60 49 18.3% 138.1 138.7 138.7 140.0 0.4 13.|-- 68.99.123.4 60 36 40.0% 140.4 140.9 140.9 141.6 0.3 14.|-- ww2.cox.com 60 44 26.7% 140.6 140.9 140.9 141.8 0.3 Fri Apr 5 18:19:21 PDT 2013 Best regards, Constantine.

Fiber plant APC vs UPC... once again...
by Jeff Kell 06 Apr '13

06 Apr '13

We are looking into doing cableTV/HFC distribution on campus, and fiber runs for HFC typically run APC connectors to avoid reflectance on the analog HFC signal where it is significant. We we're looking at converting some existing data UPC to APC for existing runs, and on the new ones either do a parallel split (UPC and APC) or just stay uniform (research seems to indicate APC is the winner). In asking some other groups (EDU LAN managers) I've heard both extremes... stick with all APC (and jumper APC-to-UPS on gear to data terminations), and I've heard the exact opposite (UPC is fine, just jumper UPC to APC at the terminations). The last time I asked here, the consensus seemed to be APC was ok, or else do parallel splits. My best understanding is that going APC across the board, and just using jumpers (APC to UPC) at the data ends should be fine, and I'm leaning in that direction. Are there any significant issues there? Do APC terminations "confuse" a data OTDR since you're now missing the expected reflections? Other issues? Before the RFQs go out on the fiber expansion, I'd like to have a clear goal in mind here :) Any reason NOT to go APC for the installed fiber plant and just adjust the terminating jumpers based on the endpoint targets? Thanks (again), Jeff

Speedtest Results speedtest.net vs Mikrotik bandwidth test
by Lorell Hathcock 05 Apr '13

05 Apr '13

All: I am having some speedtest results that are difficult to interpret. I am a small WISP multi-homed with Cogent and Level 3 in Houston, TX. I am running BGP with each with 100 Mbps+ on each link. Some of my customers have begun complaining that they are not getting the proper speeds. They are using speedtest.net and/or speakeasy.net to test the results. My network is Mikrotik based and as such, I have access to Mikrotik's built-in bandwidth testing. With a laptop on site, running against speedtest.net (which kicked me over to the Comcast speedtest server instance) I can only get 4 Mbps up and 1.5 Mbps down. That is consistent on their desktops too. We eliminated their routing equipment and other consumers of the bandwidth and tested and got similar results. But when we run the Mikrotik bandwidth tests (even to off-net Mikrotik devices in Hawaii and Mission, TX) we get 25+ Mbps synchronous. We have run traceroutes to various traceroute servers and they go through Cogent and/or Level 3. For the most part it does not seem to matter which path it takes, the bandwidth seems to be about the same going both routes. When we run the laptop-based btest.exe against Mikrotik bandwidth test servers, the laptop got significantly better results (14 Mbps) , but not 25+ Mbps. It is almost like there is a Java based problem with speedtest.net. Thoughts? Thanks, Lorell Hathcock

Ok; I've got a Main Page up at BCP38.info, as well as some supporting Glossary articles, and the first of a series of writeups on 38 for audiences of different sizes and types: http://www.bcp38.info/index.php/Information_for_end-users I invite comments, contributions, editing, and people telling me politely that I'm out of my mind. :-) If you wanna write the articles for larger sites, that'd be great too, yeah.
