RE: 600,000 routers bricked

[Robert Jacobs]

If you do a bit more digging the ISP is not Lumen ... It is a well known ISP 
and I recall reading about this outage when it happened.  I don’t know if 
indeed this was a botched attempt to gather a bot network or like some said an 
intentional act to get attention.

Lumen USED TO HAVE a walled-garden they dropped people into when their 
links/network ran amok.. at least in legacy-qwest/century-link consumer 
connectivity situations.
maybe that's gone now?
maybe the part of the affected network for this incident didn't have that 
capability?

RE: Texas internet connectivity declining due to blackouts

[Robert Jacobs]

How about letting us Texans have more natural gas power plants or even let the 
gas be delivered to the plants we have so they can provide more power in an 
emergency.  Did not help that 20% of our power is now wind which of course in 
an ice storm like we are having is shut off... Lots of issues and plenty of 
politics involved here..

RE: Are there inexpensive DWDM products?

[Robert Jacobs]

We use and love Infinera XTG Muxes for our P2P extensions off the main optical 
core.  They have a line of manageable 8 channel DWDM passive mux that you can 
get basic up down traps and optical information about each channel.  You can 
use grey market or OAM tuned ten gig transponders in your switches or routers 
and patch into the mux.  There is an option to add an amp if distances are too 
great.  About 6K for a pair of the muxes and tuned optics are grey market so 
your price will vary based on the vender you purchase from.  We use Precision 
for the grey market optics and have been very pleased with the price vs's value 
and support.

Subject: Are there inexpensive DWDM products?

We have several buildings and a couple data centers spread around the city and 
interconnected via dark fiber. It's a very simple setup - no ROADM, no real 
ring, no extended layer-2 or layer-3 via the optical gear.


Pretty much we just mux/demux a channel for each building so that each building 
sees the two data centers directly even though the fiber span may wind through 
a couple buildings along the way. In some cases, the distance is short enough 
to use colored optics in the network gear, but mostly the distances are just 
long enough to warrant transponder cards.


All that being said, a lot of the gear is approaching end of life (support in 
some cases). I'm not an optical guru but I can muddle my way through with Cisco 
ONS and I'm aware that Ciena and Fujitsu also have similar products. We really 
don't have budget for a large optical refresh effort. However, we've saved some 
money here and there in the routing/switching arena by leveraging Arista and 
even Cumulus. I'm wondering if there are smaller players in the optical arena 
that have a good quality/price value?


Again, we don't need sophisticated features... we primarily have 2-to-4 1Gb and 
10Gb ports required per site, then we mux those onto a wavelength and extend it 
to the two data centers. Most buildings are set up the same way, each on a 
different wavelength so the don't even see each other... only the data centers.


If you guys know of any optical gear that you can vouch for (and which costs 
less than a small house), we would greatly appreciate it. Thanks

RE: DWDM on 250 Km dark fiber without re-amplification

[Robert Jacobs]

Polarization and dispersion will come into play at these distances if you plan 
on running a DWDM system.  In that world you get what you pay for as a rule.  
The more expensive gear is more forgiving to fiber that is not 100 % up to high 
quality.  Most small one or two RU gear from all the vendors mentioned have 100 
gig cards that will be 100 gig on the DWDM side and break it out to 10 sfp Plus 
ten gig ports for the client side.  Another thing to look for in this is link 
down propergation ... you will want the client facing links on both sides of 
the optical span to go down if the span goes down.  Good luck with your quest

You will want to request an OTDR characterization of the dark fiber path from 
its owner. If you can post OTDR "shots" with full resolution images in a 
lossless image format to the list, we may be able to take a guess if the 
distance is feasible without amplification inline.

For equipment choices you're looking at the usual vendors for DWDM long haul 
ROADM chassis such as Ciena, Adva, Huawei, ZTE, Infinera, etc.

If you simply want to do point to point DWDM mux:demux on the 250km fiber, your 
choices will be different than if you want the ability to insert a chassis at 
an intermediate location and drop or insert wavelengths.

It may be possible, at a lower cost than buying 100GbE capable DWDM chassis 
type systems, to do a single router-to-router linecard link with coherent 
100GbE signal with FEC on the 250km path. Again this will totally depend on the 
OTDR results and link budget available.

RE: Optical transceiver question

[Robert Jacobs]

Not buying fresh veggies here... All optics have about a 5 db range that the 
vendor will say it is good.  The better venders stamp the output power on the 
optics but not all do this... What he said is to achieve the 60 Km selling 
point you would have to have all the optic be on the high side of the db TX 
power... I have never heard of a 60 Km rated optics and it would seem they 
should be saying 40 to 60 not just 60.  It would be nice to say I only want the 
optics that have an output on the high side and will accept only a 1 db 
variance but have never seen that in reality.  Most are in the middle..

What you're saying is if you purchase ten identical optics with the same SKU, 
and put them on a few hundred meters of coiled SC/UPC to SC/UPC simplex fiber 
and an optical power meter on the other end, they're showing varying real world 
Tx powers from between +0 to +5dBm?

That's not right at all, they're supposed to be sorted at the factory by their

They probably do, but only in the deep runic debug mode (nofeep) which was 
never a recommended practice unless you had the TAC on the 'phone.  
I have a couple of old 48si boxes hanging around in the lab LAN - Extremeware 
7.8.4 certainly doesn't understand "show port n transceiver".  I think this is 
XOS only.

RE: Netflix VPN detection - actual engineer needed

[Robert Jacobs]

Seems everyone continues to forget the content providers are not Netflix...They 
are the Disney, Discovery, NBC, Turner ect... These are the ones that put 
clauses and restrictions in their licensing and re-broadcast agreements forcing 
things like Netflix is doing..

I don't blame them for blocking a (effectively) anonymous tunnel broker.
I'm sure their content providers are forcing their hand.

RE: carrier grade fax boards?

[Robert Jacobs]

I would not consider any fax board "carrier grade" that uses sip  sip to 
pots for faxes is still hit and miss.

What would "carrier grade" even *mean* for a fax board?

RE: Cogent - Google - HE Fun

[Robert Jacobs]

Don't like what Cogent is doing but just to bring this back to reality Matthew 
and others out there... What content do you think Google has or any other big 
content provider that is IPV6 only or gives an IPV6 only response to a query 
from Cogent that would not work via normal IPV4 routes and IP's.. Till we have 
exclusive content on IPV6 or it is a shorter, faster, bigger, better path then 
we are still fighting this uphill battle to get more adoption of IPV6 and it 
will not matter to the majority of Cogent customers that they can't get full 
IPV6 routes and connections from Cogent.

Subject: Re: Cogent - Google - HE Fun

Mark,

I certainly agree that intentional harm of a purely malicious nature is to be 
discouraged.

What I proposed, as an alternative to some of the more extreme mechanisms being 
discussed, is a mechanism whereby IPv6 _customers_ of Cogent transit 
services--and who also receive IPv6 transit from at least one other 
relationship--can modify their IPv6 advertisements to Cogent such that they 
utilize that transit link with Cogent for the one thing you can reliably count 
on it for in the IPv6 world: reaching other Cogent IPv6 customers, especially 
the single-homed ones.

In essence, adding BGP community “174:3000” to your IPv6 advertisements to 
Cogent instructs Cogent that this route should only be advertised internal to 
Cogent and to Cogent’s customers.  It should not be announced to peers.  
Combining that with prepends of your own AS in the IPv6 advertisements to 
Cogent also reduces traffic from other multi-homed Cogent IPv6 customers.  In 
any event, if enough Cogent customers do this, it does greatly reduce the 
amount of traffic that Cogent gets to transit from their various IPv6 peers 
while still avoiding harm to innocent end-users (or for that matter, to guilty 
end users).

The mechanism I proposed has numerous benefits:

1.  It utilizes only a mechanism created by Cogent and documented for use by 
Cogent transit customers to achieve routing policy that benefits IPv6 customers 
of Cogent.
2.  It causes no harm to single-homed Cogent customers.
3.  It causes no direct harm to Cogent.  The sole indirect harm that it might 
bring upon Cogent if adopted en-masse would be to significantly drop the amount 
of traffic crossing Cogent’s SFI peerings on IPv6, which I acknowledge may have 
consequences for Cogent.  If it did have such consequences, it’s Cogent’s game 
and Cogent’s rules.  They could change it any time.  If it indirectly harms 
Cogent by lowering overall traffic volume on paid multi-homed customer transit 
connections, Cogent could easily remedy that by becoming an IPv6 network that 
one would want to exchange IPv6 transit traffic with rather than being an IPv6 
network that one begrudgingly pays because one does business with others who 
are Cogent single-homed.

I do reiterate, however, that I would strongly discourage any kind of routing 
tricks that leave the innocent Cogent customers out in the cold.  That hurts 
those Cogent customers as well as you and/or your own customers and users.  
Please, someone, think of the end-users here.

My advice to Cogent would be to remember something real simple:  When Big Boss 
#1 at RandomCorp has no trouble reaching Google services all night every night 
at home and then he comes to work and his office Internet does everything but 
Google….  What he’ll remember is “Charter works with Google, whoever we’re 
using at the office doesn’t.  Let’s switch.”  It’s shocking to me that an ISP 
with a retail segment thinks you can survive if Google doesn’t work, no matter 
what Google did to ensure it played out that way.  Frankly, Google could scream 
that they cut Cogent off because they didn’t like Cogent’s face and no one at 
retail would care.  They just want their Gmail back.  If Google wanted to force 
the issue faster, they could just stop the IPv4 transit routes to Cogent.  I 
think they’re taking a more balanced and conservative approach though.

Thanks,

Matt Hardeman

RE: Multicast stream monitoring tools

If you are in the  Video content delivery business using mcast then these folks 
are one of the leaders.  You can put multiple probes and make sure your mcast 
coming off source is solid, through the core router solid, and at the edge...

If it is not capacity saturation, it may have something be membership 
stability.  Not knowing anything about your IP multicast configuration, it is 
impossible to say anything concretely with certainty

This is to say however, you may want to also be sure to monitor membership, 
interface, port, PIM, ..., states.

All the way down to spanning tree recalculation, you may not notice it with 
unicast, but anything that might prevent a stream from being forwarded due to a 
join state disruption are sometimes the causes of these types of events.

It is a bit old and may not be the latest copy, but here is a copy of Bill 
Nickless' very handy troubleshooting methodology you should have
handy:

  


Unfortunately there isn't much in that paper about Layer-2 related issues as I 
alluded to above, but hopefully it gets you part of the way there.
