Re: mpls over microwave

The only weirdness I encounter is if I have multiple equal-cost routes to the same location, one over MPLS and one not, end up having ping/unreachable issues from my monitoring equipment. The solution has been to cost one path (the MPLS) lower than the other. The only other problem I had was with radio's that didn't support larger 9000+ byte MTU packets - we've phased that radio out for now. if you run MPLS with 1500 byte MTU, you'll have issues with 1500 byte packets with the DF-bit set. That was a nasty discovery in the production network, your mileage will not vary with that problem. I'm curious why you'd have multiple paths in your network (equal-cost to boot) where some support and others don't. Mark.

We even had a dirty fiber issue with their uplink (due to the MMA owner) and Cogent stayed on the phone with me for hours and got it handled before we hung up the phone. So great NOC too. We pick up Cogent as one of our upstreams, primarily for who they have on-net that others do not (or can be accessed shorter through). We haven't had any major issues. The sales folk were persistent, but the turn-up was good as has been contact with the NOC (primarily to get BGP prefixes updated regularly). We use NTT too, and a bunch of others, and the experience has generally been the same, i.e., nothing major to complain about. Then again, close to 70% of our non-African traffic is peered away at the 4x major exchange points in Europe, and the upstreams only cover the rest. So there could be some co-relation there. Mark.

Re: Low cost WDM gear

Re: Low cost WDM gear
Hi Enviado, I cannot recommend FiberStore as I had a bad experience with them. I needed to cover only 3km from A to B side. When using 10km optics, I saw a loss of over 5db with their passive mux inserted into the path which created a total loss of over -20db which is outside of the tolerances for our equipment with 10km SFP+. Using another vendors low insertion loss mux corrected our issue. I am sure if you are using an 80km optic, you may be able to tolerate a higher insertion loss to cover 60km. I also notice that their CDWM optics averaged about 3db less in power output when compared to other vendors.

Re: Low cost WDM gear
Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km using XFP. To cover the distance you are considering, you would need to insert an amplifier. Depending on the number of channels you require, a passive solution with an amplified would still be less expensive than an active solution. When I was conducting my research, I could not find an active solution under $25K.

Re: Low cost WDM gear

If you are launching out of a router the best pluggable optic you can generally get is rated at 80km, 10GBase-ZR, but even a passive mux at each end shaves some of that distance off. 300km is going to require amplifiers at intervals across the span.

Re: Low cost WDM gear
Any tips on getting other people to use colored optics or is it not the issue that I'd expect it to be? This particular application would be to connect two datacenters together over dark fiber and transport customers across as needed. I could see it being a little difficult to get someone to buy special optics (even if you can source generic ones) for your route. I wouldn't have an issue, but then again, I'm fairly easygoing... and thrifty. Another scenario before me is within a datacenter when trying to save on cross connect charges. Spending a few thousand bucks once sure beats $300/month forever. I'm working with several other ISPs, some of which don't want another entity to be between them and their upstream. [Cut rambling short.] I guess the short of it is, active solutions are expensive, so do that or don't. ;-) I did get an AlcaLu quote under $25k once, but it wasn't far under. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com - Original Message - From: Kenneth McRae kenneth.mc...@me.com To: Mike Hammett na...@ics-il.net Cc: NANOG nanog@nanog.org Sent: Saturday, February 7, 2015 1:12:01 PM Subject: Re: Low cost WDM gear Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km using XFP.

Re: Low cost WDM gear
Multiple 10G, yes. I'll reach out to the vendors mentioned to see how they line up, but it looks like I need to look into amps for the passive gear. There's 8 huts between the two ends, so no shortage of opportunities to amplify the signal. I'll know more about that when I get the amount of loss along the route. Most people I know leasing circuits are doing so because dark isn't available or is otherwise ass expensive due to above shortage. The last quote I got for dark out of a useful facility was like $2M. 100+ miles was like $200k, the last 10 miles or whatever was the balance.

Re: Metaswitch ax1000 as a RR
I've been testing various vRR solutions recently but haven't taken a long look at Metaswitch, but I may contact them. On paper, their RR doesn't support all the AFI/SAFI combinations I require. There are a few commercial options which have come to market very recently namely: ALU VSR Juniper vMX (vRR version) Cisco XRv (IOS-XR) Cisco CSR1000v (IOS-XE) I can't give exact numbers, but all of them are much faster on pretty basic newish Xeon hardware than a Cisco ASR9K/Juniper MX with the latest and greatest RP, while using almost no CPU really. They don't need much RAM either, 8-16GB is more than enough. XRv and the CSR1000v will run under ESX fine, and are packaged/documented to deploy that way. vMX/VSR will but it's not really a supported/documented thing yet, they are currently supported running under Qemu/KVM. One issue with VSR/xRV under ESX right now is they have no display drivers/output, so you have to use a virtual serial port which is only supported with the Enterprise+ version of ESX for some inane reason. XRv is 32-bit for now, the others are all 64-bit. CSR1000v has definitey been around the longest. XRv, vMX, and VSR all get built the same time as the router software now so they get features when the router software does. You will find more features in them than the CSR1000v and new service provider features will be in XR before XE. For instance Cisco has something called Optimized Route Reflection where a vRR will simulate the IGP network rooted at each client and send the best BGP paths specific to each client. It means you can have a centralized RR without running into the issue of it selecting paths based on its position in the network vs. the client. That's a beta XRv thing but I don't know if you'll ever see it in XE. All of them support pretty much every major AFI/SAFI. Pricing wise the CSR1000v is going to easily be the cheapest option.

Sure, everyone has different needs and there are certainly lots of use cases for having your own fiber.

Re: Low cost WDM gear
Mike, Lighting up dark fiber is very similar to doing fixed wireless links (which you are familiar with). There are different components involved in making a solutions work for each of the problems you have stated there is solution, and yes you have to calculate the loss and match power / optics to make it work. FYI.. all CWDM/DWDM Muxes are passive ... :) Active components (can be external or integrated). If you want to do a direct run, from DC to DC using the Dark Fiber, you will need to have signal regeneration (or you may be able to get away with amps). It is commonly expected for the transport provider to hand off the live circuit using standard SFP/SFP+, which means that they have to use a 'media converter' of some sorts to covert from Colorized Light to Standard 1330 or 880nm hand off. If you want more info, hit me off list. Regards.

I'll reach out to the vendors mentioned to see how they line up, but it looks like I need to look into amps for the passive gear. There's 8 huts between the two ends, so no shortage of opportunities to amplify the signal. I'll know more about that when I get the amount of loss along the route. Most people I know leasing circuits are doing so because dark isn't available or is otherwise ass expensive due to above shortage. The last quote I got for dark out of a useful facility was like $2M. 100+ miles was like $200k, the last 10 miles or whatever was the balance. Even $100k for gear (two sides and some amps) pales in comparison to $2k+ a month for the next 20 years for a single channel. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com - Original Message - From: Phil Bedard bedard.p...@gmail.com To: Mike Hammett na...@ics-il.net, NANOG nanog@nanog.org Sent: Saturday, February 7, 2015 1:17:48 PM Subject: Re: Low cost WDM gear Is this for 10G?

If you are launching out of a router the best pluggable optic you can generally get is rated at 80km, 10GBase-ZR, but even a passive mux at each end shaves some of that distance off. 300km is going to require amplifiers at intervals across the span. Who is providing the fiber? I'd start talking to traditional transport vendors. Ekinops as mentioned is probably decent at a lower price, Adva works well and isn't all that expensive, even Cisco has gear reasonably priced.

Low cost WDM gear
Faisal, I worked directly with FiberStore's engineers to determine the optics and mux needed for my use case. They recommended the mux and the optics for the 3km distance. You can always buy stronger optics, but that is not point I am making. I provided the scale and scope of the project and they provided the BOM to deliver the required service. When the equipment failed, FiberStore refused to honor their return policy and issue an RMA until we threatened legal action. Same sales scenario with OSI Hardware.. They provide the BOM with passive muxes and 10km optics and it works with no problem. In this scenario, I can definitely blame the manufacturer. No to mention the terrible technical support that they offer.

Re: Low cost WDM gear
That's why I engage the engineering resources on their end to make sure the chosen candidate will support the use case. I have now performed an A/B comparison and the FiberStore gear is inferior. Excessive loss on the mux and optics. Just for comparison sake, I should say that we've bought passive DWDM muxes and SFP+'s from FibreStore, and we've had good experiences. At the lower end of the market, production quality can definitely vary, which means significant variances in optical losses. When we ordered from FibreStore, we specified the Optical Loss values that we were able to accept. They tested the muxes before shipping, and selected the ones which fitted our requirements. Out of all the SFP's we bought, there were one or two DoA. FibreStore replaced this without issue. I think the important thing to remember (particularly when buying cheap) is that you need to know what you're buying, and what the risks are. With this in mind, it's possible to save money and get a decent product with some careful specification and management of the purchasing process. If you're not too sure what you're after, then I'd suggest spending more money and buying from a supplier who's more set up to hand-hold you through the process. Simon
Re: Low cost WDM gear
Yes can do long distances without need to amplifier site (train tracks for example) but you need to make sure ground is stable and if using track bed of train track that the ballast is good and stable else ground tremors affect the signal quality.

That's true up to a point. Specs are only as good as the entity providing the data.

Mike, Look into SolidOptics. www.Solidoptics.com Great Mux and Add-drops, plus fantastic optics. We are not optical engineers so when we have had questions about new links their team has always been open about what will and what won't work based on what we are trying to accomplish. We are only using their CWDM passive mux and various optics, been extremely happy on price and performance. No issues.

Agreed, and to add one more little point.. Now they have DWDM CWDM Muxes which have an even lower insertion loss .. (new products, currently not listed on the website).

I have now performed an A/B comparison and the FiberStore gear is inferior. Excessive loss on the mux and optics. Just for comparison sake, I should say that we've bought passive DWDM muxes and SFP+'s from FibreStore, and we've had good experiences. At the lower end of the market, production quality can definitely vary, which means significant variances in optical losses. When we ordered from FibreStore, we specified the Optical Loss values that we were able to accept. They tested the muxes before shipping, and selected the ones which fitted our requirements. Out of all the SFP's we bought, there were one or two DoA. FibreStore replaced this without issue. I think the important thing to remember (particularly when buying cheap) is that you need to know what you're buying, and what the risks are. With this in mind, it's possible to save money and get a decent product with some careful specification and management of the purchasing process. If you're not too sure what you're after, then I'd suggest spending more money and buying from a supplier who's more set up to hand-hold you through the process. Simon
Re: Low cost WDM gear
You can do ~500km without inline amplifier sites using EDFA+Raman+ROPA, but you are going to need some serious optical engineering to make that work. The more standard way to do it is amplifier sites every 80-100km for EDFA. If you are doing 10GigE you will need to allow for DCM also.
