It all depends on what the links are like between here [1] and there [2]. These sites may or may not give you a good indication of what you're really receiving. I'm connected to a major carrier with national presence in a reasonably sized metropolitan area (over 260,000 in Greensboro, but over 1.5 Million in GSO/Winston Salem/High Point). It all depends on what they're really selling you. A 100 Mb "Internet" connection to their core isn't going to be worth squat if the majority of your traffic leaves their core and they don't have the connectivity/SLAs to the other carriers to get you the "Internet bandwidth" you crave and/or need. Then again, if you're in a large metro area, and many of the services you depend on are based in the area, you likely won't have a problem. Again, to what/where are they guaranteeing you 100 M? They can only guarantee what they can control. Once it hits another carrier, all bets are off, depending on what the SLA is with their connected carriers. [1] & [2] - these are relative terms.

Yes obviously they are basing their speeds on the link from us to their first hop which I believe is in Colo. Springs. So I should be able with the sites your giving get close to the 100mb? Thanks I have not signed off on this yet so I will be doing some more testing. dave From: Raper, Jonathan - Eagle [mailto:[email protected]] Sent: Wednesday, January 05, 2011 8:22 AM To: NT System Admin Issues Subject: RE: Metro Ethernet ? Gotcha. The question is, to what are they claiming you're getting 100M? Probably only your connection to their local backbone, which may or may not be worth it. IMO, you need to know more about their backbone connectivity and SLAa to other providers. I've got a 10 M Full duplex fiber connection from Time Warner, and using this site, I show better than 9.2 M in both directions: http://www.timewarnercable.com/East/learn/hso/speedtest.html Using this Qwest site, I got 8.450 M down and 9.052 up: http://washington-dc.speedtest.qwest.net/ Using this site in Las Vegas, 7.25 down, 6.46 up: http://test.lvcm.com/burst/ Using speed test to a server in Greensboro, 8.99 Down, 8.66 Up: http://www.speedtest.net/ >From here to a server in LA on the same site, 8.14 down, 5.29 up.

Jonathan, I am switching over from our 10mb to 100mb qmoe starting with my signoff next week. They are (Qwest) still trying to get the circuit to verify at 100Mb. It currently to them shows 82. How can I can test this with just a pc on my end? I went to qwest.speedtest.net and it isn't anywhere near even the 82 they report. How do I the customer validate the speed I am paying for? dave From: Raper, Jonathan - Eagle [mailto:[email protected]] Sent: Wednesday, January 05, 2011 7:33 AM To: NT System Admin Issues Subject: RE: Metro Ethernet ? We switched to Metro-E over fiber about 6 years ago, and haven't looked back, though it isn't MPLS. We just have a Point to Multi-point layer 2 network, with them breaking out switch ports at my core for each remote site. So for all intents and purposes, from my standpoint, it is a handful of point to point layer 2 connections. One thing I had to beat into my providers' head was verifying the speed and duplex of their equipment. For some, we needed 100 full, and for others, we needed 10 full. It all depended on what gear we had at each site. Even once the setting was changed, sometimes it would take an equipment reboot (theirs AND ours) in order for it to settle properly. You should not have to dumb down the connection speed to 10 mbps, as they are rate limiting on their equipment down to 5 Mbps (just like what we have). What is your terminating equipment, and are you seeing interface errors? (I know you said collisions, but what exactly are your interfaces saying?) Jonathan L.

Folks, I am converting our network from point to point to MVLS/Metro Ethernet. What I am noticing at some sites is that performance is worse that with the point to point circuit. Ping times greatly increased, collisions, etc. I've been working with my provider to get this resolved. First they thought it was a speed mismatch issue, so the provider's equipment and my equipment were changed to the same setting (full 100). That's not working and now we'll probably change it to full 10 (since the allocation is 5 Mbps anyway). I can also do some rate shaping on my switches, but it's a PITA and I was hoping to avoid it. Anyone else have these issues with conversion? Some sites are fine, others are not. All have same switches, model, firmware, config for trunk ports. I haven't pulled out my bag o software to look at what's on the pipe, anyone have any that would be best for this scenario? I have Praesser but I really need a site to site test/analysis tool. I just downloaded Qcheck and will see if that does it. I've also asked my provider to give me some statistics on traffic they see. Recommendations and comments welcome.
