We'll I would for one be very interested if the 8 ARP packets a second count 
against the caps.

Given len of 46 or 60 is not much, but that's about a gig of traffic almost 
assuming 8 of those a second happen(and my cold medicine addled mind is 
working).  I'm sure it's not just that when it comes to garbage received on

Can someone at Google that has some control over how Google’s system that says 
an IP is suddenly in Iran please contact me off list ASAP.  We can not wait a 
month for your tool to remove this.

Also in the future that tool needs to ping the ip and check the RTT time and 
compare to well established GEOIP databases before flagging ip’s as not 
belonging to the country they’re actually in.  We had to change our office

Re: Multicast Internet Route table.

2014-09-02 Thread Corey Touchet
14 years at Verizon Wireless and I despised the crop of multicast products
that seemed to pop up from time to time.  Even in a fully controlled
network multicast remains at best black magic.  There are ways to make it
more reliable and prevent people from ruining the setups especially for
PIM type setups, but I would agree with others, unicast has better
advantages though you have to keep up with the bandwidth curve.  Content
delivery systems moving the content closer to edge customers makes this
less of a problem as well.

Torrent style distribution appears to be particularly effective as long as
you can maintain a pool of users to distribute the content.  Blizzard has
made good progress using this for game updates will a fallback to http if
you can¹t get the content via torrents.

CAIDA used to do some, but I'm not sure they have anything active any

The once NLANR inspired and run Beacon project hasn't completely died
out, there is this I found at ja.net for instance:

  http://www.beacon.ja.net/

Interdomain IP multicast has practically since the beginning
been a notoriously niche and limited service compared to unicast
service.  There are a handful of reasons for that, but I think you will
find it becoming decreasingly available rather than more so on
interdomain basis.

There is likely a fundamental design flaw in that the cli is not itself

 This would be my humble suggestion:
 
 - lines provider runs fibre pair from each home to co. By
 default the lines provider installs a simple consumer
 terminal, with gigabit Ethernet outputs and POTS.

The problem with this is it allows the lines provider to dictate
the technology to be used by all higher-layer service providers.

IMHO, this is undesirable, because it blocks innovation and
service differentiation on this basis.

Ideally, the lines provider is simply a lines provider and provides
a number of dark fiber pairs between the serving wire center (what
you called a CO) and each premise served by the SWC.

Termination at the customer end should be a box in which a customer
terminal can be installed and the fibers should all be terminated on
some standard form of patch panel (ST or LC probably preferred,
but others may be acceptable).

It would then be up to the service provider(s) to provide the terminals
and decide between customer self-install and truck-rolls for service
turn-up.

 - lines provider provides a reasonably oversubscribed
 service to soft hand over to ISPs (think 96 Gbps lines
 to 2 10gbps ports). Perhaps upgrading so such a ratio
 never becomes congested could be a requirement?

Putting the lines provider into this part of the equation preserves
many of the problems with the existing model.

 -  lines provider also rents individual lines to ISPs
 which they can use directly. Rent should be lower than
 soft handover.

Now you¹ve got competition operating at a disadvantage to the
incumbent lines provider, preserving this aspect of the problems
with the current system. IMHO, this should be the only service
the lines provider is allowed to sell. In that way, the lines provider
is not in competition with its wholesale customers.

If you want examples of how well the model you propose tends to
work, look no further than the incredible problematic nature of MCI¹s
attempt to offer local phone service over Pacific Bell/SBC/ATT
circuits.

 This way ISPs can easily offer services. POTS over VoIP
 can be setup on installation of the terminal (so
 handover to the ISP is seamless). Finally business and
 residential services can also be provided over the fibre
 directly (this will be attractive to ISPs with many
 ports, to reduce costs, and premium/business ISPs to add
 control).

This is also true of dark fiber pairs, with the added advantage
that the service providers can differentiate themselves on
chosen technology, can offer innovative services and can
leverage existing infrastructure to deploy newer technologies as
they develop.

 
 - ideally the lines provider would aid in providing cheap
 backhaul from the co (while still allowing 3rd party
 users to bring fibre in).

I don¹t think this is so ideal. Again, it creates an opportunity for
the lines provider to leverage their infrastructure in a way that it
can become a barrier to competition. This is, IMHO, the opposite
of good.

 Wholesale mode. Doable.
 
 Works best if the lines provider is not a service provider;
 or regulation in your market ensures a service provider who
 is also a lines provider is mandated to unbundle at
 reasonable cost.

Even when mandated to unbundle at a reasonable cost, often
other games are played (trouble ticket for service billed by
lines provider resolved in a day, trouble ticket for service on
unbundled element resolved in 14 days, etc.).

IMHO, experience has taught us that the lines provider (or as I
prefer to call them, the Layer 1 infrastructure provider) must be
prohibited from playing at the higher layers.

The only actual residential data I can offer is my own. I am fully dual
stack and about 40% of my traffic is IPv6. I am a netflix subscriber, but
also an amazon prime member.

I will say that if amazon would get off the dime and support IPv6, it
would make a significant difference.

Other than amazon and my financial institutions and Kaiser, living
without IPv4 wouldn't actually pose a hardship as near as I can tell from
my day without v4 experiment on June 6.

I know Kaiser is working on it. Amazon apparently recently hired Yuri
Rich to work on their issues. So that would leave my financial
institutions. 

I think we are probably less than 5 years from residential IPv4 becoming
a service that carries a surcharge, if available.

 Do you have IPv6 deployed and available to your entire customer
base, so
 that those who want to use it can do so?  To my way of thinking,
CGNAT is
 probably going to be the number one driver of IPv6 adoption amongst
the
 broad customer base, *as long as their ISP provides it*.
 
 Add to that over half your traffic will switch to IPv6 as long as
 the customer has a IPv6 capable CPE.  That's a lot less logging you
 need to do from day 1.
 
 That would be nice, but I¹m not 100% convinced that it is true.
 
 Though it will be an increasing percentage over time.
 
 Definitely a good way of reducing the load on your CGN, with the
additional benefit
 that your network is part of the solution rather than part of the
problem.
 
 Being on the content provider side I don't know the actual percentages
 in practice, but in the NANOG region you've got Google/Youtube, NetFlix,
 Akamai  Facebook all having a significant amount of their services v6
 native.
 
 I'd be very surprised if these four together weren't a majority of any
 consumer-facing network's traffic in peak times.



Upgrade Path Options from 6500 SUP720-3BXL for Edge Routing

2014-07-29 Thread Corey Touchet
I’m curious what other providers have gone with when moving away from 
SUP720-3BXL 6500 platforms.  I’m platform agnostic and just as comfortable with 
Juniper as with Cisco.

It’s a conversation were having since the 3BXL’s are running into limits with 
the large number of prefixes, long eBGP convergence times, and 10G port density.

Basically were looking to carry multiple full routing tables from several 4+ 
carriers plus internet exchange traffic so the ability to handle 1-2M IPV4 and 
500K+ IPv6 and decent 10G port density and/or 40G options as well.  Also should 
have decent CPU capabilities so it can crunch routes in a reasonable amount of 
time.


Right now my thinking are MX480 or ASR9k platforms.  Opinions on those are 
equally welcome as alternatives, but I’d love to hear from those with personal 
experiences today vs sales people trying to tell me it would route the world :)



Thanks,



Corey T


Re: Many players make up application performance (was Re: Richard Bennett, NANOG posting, and Integrity)

2014-07-29 Thread Corey Touchet
What I would like to see is someone who sets up a VPN that has an endpoint
path that¹s the same as NetFlix.  If their streaming performance improves
that would be very telling.  Heck you could use 2 machines and do a side
by side.


However I doubt Level3 is going to sit there and lie about their
connection to Verizon being overloaded, and for Verizon to do any kind of
meaningful QOS it would require an effort on the Level3 side of the
connection as well.

I didn't pay for (x) bits/sec from some whitelist of sources only.

Along with paying $IP_PROVIDER for (x) bits/sec up/down, you are also
paying (or the product of advertising) eyecandysource to deliver a service
(w/ a level of quality).  $IP_PROVIDER plays a big role in delivering
your *overall* Internet experience, but eyecandysource plays an even
bigger role delivering your *specific* eyecandy experience.  If
eyecandystore has internal challenges, business negotiation/policy
objectives, or uses poor adaptive routing path decisions, this has a
direct and material impact to your *specific* eyecandy experience (and
some have found fixable by hiding your source IP with a VPN).

While ISPs do play a big role in this, people tend to miss eyecandystore
decisions (and business drivers) as a potential factors in isolated
application performance issues.
