Hi Brian, I know other people have posted about this, re almost getting fired. Many companies now are adopting new rules regarding employee's posting on listserves. The policy here is that employees must get another address through aol or yahoo or some other free mailserve if they want to participate in listserve discussion. The reason is spam, supposedly. My boss knows I post here, and he doesn't care that I use my work mail address. I'm smart enough to deal with spam myself. (at least he thinks so ;) The point is, that there are many companies now, at least in the Wash metro area, that are requiring employees to use an alternate mail address for any listserves they participate in.

Re: Do ATM-based Exchange Points make sense anymore?
Hello, Can you, please, explain why you didn't consider Frame Relay based exchange in your analysis? Regards, nenad Date: Thu, 08 Aug 2002 08:11 -0700 (PDT) From: William B. Norton [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sender: [EMAIL PROTECTED] Delivered-to: [EMAIL PROTECTED] Delivered-to: [EMAIL PROTECTED] Delivered-to: [EMAIL PROTECTED] Subject: Re: Do ATM-based Exchange Points make sense anymore? Hi again - A couple points (based on some interactions with folks privately). This is not an ATM is bad, or general ATM-bashing paper. It simply applies the same Peering Analysis that ISPs are applying to determine if and when IXes make sense. With the transit prices and transport prices dropping, this is a reasonable question, worthy of greater analysis than well, ATM is expensive so ATM is bad. To give you a flavor, given a set of assumptions, OC-3 (155Mbps) transport into an ATM-based IX has an Effective Peering Range (where peering across them is cheaper than transit) of 75-90Mbps, while given the same assumptions, Fast Ethernet-based IXes also at OC-3 have an Effective Peering Range of 40-70Mbps. The Minimum Cost of Traffic Exchange for this ATM solution is $122/Mbps while FastE is $80/Mbps. At higher capacity the interconnect analysis is more dramatic: Given the relatively high price point of transport and port cost, the Effective Peering Range for ATM/OC-12 Peering is a narrow 236Mbps to 375Mbps with a Minimum Cost of Traffic Exchange of $69/Mbps. The GigE/OC-12 equivalent range is 109Mbps-466Mbps with a Minimum Cost of Traffic Exchange of $25/Mbps. What was unexpected in this analysis was the Effective Peering Range Gap. When an ISP upgrades the ATM OC-3 to OC-12, the gap between the Effective Peering Bandwidth of the OC-3 (90Mbps) and the Peering Breakeven Point (the point at which the Peering Costs are totally offset by the cost savings of peering vs. transit) at 208Mbps is huge. This 118Mbps gap is where an ISP should rationally prefer to purchase transit until 208Mbps can be sent in peering relationships over the ATM fabric, and only then upgrade the peering connection to OC-12! There is also an Ethernet EPR Gap but it is only about 40 Mbps, and once at the GigE/OC-12 capacity, it gets you an Effective Peering Range up to 475Mbps. In any case, this is the analysis that the paper walks through, and since the spreadsheets are in the paper, one can muck around with the assumptions and cost points, key of which are: 1) ATM OC-3 Port Cost $8000/mo, ATM OC-3 Circuit Cost $3000/mo, ATM OC-12 Port Cost $17000/mo, ATM OC-12 Circuit Cost $8000/mo 2) FastE Port Rack Space $2500/mo, OC-3 Circuit $3500/mo, GigE Port Rack Price$5000/mo, OC-12 Circuit $7000/mo 3) Transit Price: if you peer at OC-3, you probably pay $125/Mbps, peer at OC-12,$110/Mbps 4) ATM Overhead (aka cell tax): 20% 5) Assumption that ISP upgrade capacity when avg utilization 75% Effective Peering BW Let me know if you violently object to any of these data points. These are culled from a lot of conversations in the field. The rest of the paper is simply plugging these data points into the equations and analyzing the results.

Re: Do ATM-based Exchange Points make sense anymore?
Personally, I don't believe that ATM is 'bad' for shared-fabric exchange point. I mean, it works, and solves several problems quite easy: a) it's easily distributed via SONET services to folks who are not next to the ATM switch, b) it makes interconnection between networks safer (ie, not dealing with broadcast issues on a ethernet nap), c) virtual PI connections are easily accomplished, d) there are varying degrees of interconnection speed (agreeably, less important), All of the above are true of frame relay as well, which has the additional benefit of not being funamentally incompatible with data networking. :-) e) it allows for things other than IP, or packet-based traffic to be exchanged (a la Verizons' video-portal service) (agreeably, again, less important). Ah, yes, I agree with this entirely. If you're building a voice exchange, rather than a data exchange, ATM is excellent technology. I believe Vinnie can give us some personal experience on this front. -Bill
Re: Do ATM-based Exchange Points make sense anymore?
Can you, please, explain why you didn't consider Frame Relay based exchange in your analysis? I don't have much insight into Frame Relay-based Internet Exchange Points ;-) The majority of IXes around the world are ethernet-based, with some legacy FDDI and a few ATM IXes. It is in these areas that I have done the most data collection. The same analysis could be applied to peering across WANs and MANs as compared with buying transit though. It might be interesting provided I can get some market prices for transport and ports. Why look at ATM? Right now almost everyone I am speaking with is seeing massive drops in transit and transport prices, even below the points I quoted, but with no comparable price drop in ATM ports or transport into an ATM cloud. These forces lead to a point where a connection to an ATM IX makes no sense (from a strictly financial standpoint). I have another 10 folks to walk through the paper to make sure I'm not missing anything in the analysis, and I'll post to the list when the paper is available. If you are interested I'd love to walk you through it to get your take. One point a couple other folks brought up during the review (paraphrasing) You can't talk about a 20% ATM cell tax on the ATM-based IX side without counting the HDLC Framing Overhead (4%) for the OC-x circuit into an ethernet-based IX. Since the Effective Peering Bandwidth is the max peering that can be done across the peering infrastructure, this is a good point and has now been factored into the model and analysis. Bill
Re: Do ATM-based Exchange Points make sense anymore?
It appears that for analysis purposes one has to separate access from switching. How much payload one brings to the exchange depends on port speed and protocol overhead. In that light, Frame Relay can bring similar amount of payload as Ethernet (comparable overhead) and preserve good properties of ATM (traffic flow separation).

endpoint liveness (RE: Do ATM-based Exchange Points make sense anymore?)
BGP keepalive/hold timers are configurable even down to granularity of link or PVC level keepalives, but for session stability reasons, it appears that most ISPs at GigE exchanges choose not to tweak them down from the defaults.

If the connection fabric between your routers has an MTBF best measured in hours or days, then you've got bigger problems than you'll solve with LMI. If on the other hand the MTBF is best measured in months or years, then when it does fail the failure is likely to be *in* the extra complexity you added. -- Paul Vixie
