billing systems and all of the above. I recently undertook to reconcile billing 
discrepancies for a business unit in a large corporate account (a very large intl

between their *multiple,* internal bill-back systems (which naturally factored in

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

address for any listserves they participate in. 

Hope this sheds more light on the subject.

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?

2002-08-09 Thread Bill Woodcock


 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.

2002-08-09 Thread William B. Norton



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?

2002-08-09 Thread Nenad Trifunovic




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).

Most exchange point users terminate their exchange connections on core

Even after arbitrarily adding 4% conservative overhead to the gige case,
gige is still way more cost effective.

2002-08-09 Thread Lane Patterson


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.  IIRC, Juniper is 30/90 and Cisco is
60/180.  My gut feel was that even something like 10/30 would be 
reasonable, but nobody seems compelled that this is much of an
issue.

Re: your mail

2002-08-09 Thread mike harrison


 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

There's only 6 of us.. but thanks to this discussion, we have implemented
a company policy about participating in listserve using company e-mail
addresses (note I am using my personal one here though.. just cuts down
noise from my critical email address):

HTS Policy for listserves and personal e-mail using work related
addresses:

  1. Before asking ANY technical questions, make sure you have RTFM
 and done a decent search on Google FIRST.

  2. If you communicate something that implies you have done something
 that may be illegal or questionable, even in jest, we will not
 post bail. 

  3. Please use a seperate address (it can be on our domain) for 
 non time-sensitive materials (most listserv's).






Re: Do ATM-based Exchange Points make sense anymore?

2002-08-09 Thread Paul Vixie


  What functionality does PVC give you that the ethernet VLAN does not?

 That´s quite easy. Endpoint liveness. A IPv4 host on a VLAN has no idea
 if the guy on the other end died until the BGP timer expires.
 
 FR has LMI, ATM has OAM. (and ILMI)

Adding complexity to a system increases its cost but not nec'ily its value.
Consider the question: how often do you expect endpoint liveness to matter?

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.

The Cidr Report

2002-08-09 Thread CIDR Report



This is an auto-generated mail on Fri Aug  9 23:00:01 PDT 2002
It is not checked before it leaves my workstation.  However, hopefully 
you will find this report interesting and will take the time to look 
through this to see if you can improve the amount of aggregation you 
perform.

Check http://www.employees.org/~tbates/cidr-report.html for a daily
update of this report.

NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for
the regional version of this report.

NEW: Check http://www.employees.org/~tbates/autnums.html for a complete
list of autonomous system number to name mappings as used by the CIDR-Report.

The report is split into sections:

   0) General Status
   
  List the route table history for the last week, list any possibly
  bogus routes seen and give some status on ASes.

   1) Gains by aggregating at the origin AS level

  This lists the Top 30 players who if they decided to aggregate
  their announced classful prefixes at the origin AS level could 
  make a significant difference in the reduction of the current 
  size of the Internet routing table. This calculation does not 
  take into account the inclusion of holes when forming an aggregate
  so it is possible even larger reduction should be possible.

   2) Weekly Delta

  A summary of the last weeks changes in terms of withdrawn and
  added routes. Please note that this is only a snapshot but does 
  give some indication of ASes participating in CIDR. Clearly,
  it is generally a good thing to see a large amount of withdrawls.

   3) Interesting aggregates

  Interesting here means not an aggregate made as a set of 
  classful routes.  

Thanks to GX Networks for giving me access to their routing tables once a
day. 

Please send any comments about this report directly to CIDR Report
