hey,
For availability I think it is best approach to do many small edge
devices.
This is also great for planned maintenance. ISSU has not really worked
out for any of the vendors and with two small devices you can upgrade
them independently.
Great for aggregation, enables you to dual-home

We never have.

Thanks Valdis for clarifying this. Based on this thread discussion, I’m getting
this understanding as well.

Hi Job,
While doing some study, I recently came across this
https://drpeering.net/white-papers/The-Folly-Of-Peering-Ratios.html
This discussion was from from a Nanog meeting that took place a long time ago.
This made me interested to know whether there is some actual numbers behind
those
Dear Mike,
Regardless of very few direct answers, I found this discussion very
interesting. I think one possible reason for not having any specific numbers,
as some members have already pointed out, is there doesn’t exist any. As an
outsider, with zero hands-on experience in ISP field apart
Hi Keith,
Honestly? I don’t! I have never worked with an ISP or similar. If I ever get
the chance, that would be exciting. Until then, I think this platform is one of
the best places where I can get the answer from the people who has first-hand
experience in this field.
Your classification is
As I recall, yes that is true.

Thanks Valdis for mentioning the classifications. I’ve used ISPs as generic
word. But, you’re right, it’d be better if I had distinguished the CPs, ISPs or
the Transits specifically. However, thanks to the community, they’ve understood
and provided me some really helpful answers.

Just remember that without "leech" networks like Comcast, everybody who's
selling transit to content providers would be having a hard sell indeed.

Warren,
I like the cheap price of the LeoNTP. The only reason I prefer the Tm1000a is
that it has an embedded web server, which lets me monitor the satellite
constellation visibility. Otherwise, except for oven-controller time clocks, it
seems obvious that the $2000+ GPS NTP servers are

Having an inbound:outbound ration of 10:1 is known as a leech ...

Why would you think that "Heavy Inbound" signifies a greater inbound:oubound
ratio compared to "Mostly Inbound"?
To me "Heavy Inbound" means that there is more inbound than outbound and
"Mostly Inbound" means exactly that -- mostly/usually/exclusively inbound with
the occasional outbound
Hi Martijn and Josh,
Thank you for your detailed explanation. Let me explain my requirement so that
you may help me better.
According to PeeringDB, Charter (Access), Sprint (Transit), Amazon (Content)
all three of them are ‘Balanced’. While, Cable One, an Access ISP says it is

Thank you Aaron,
This is great. This gives an interesting insight regarding CDN as they seem to
play a big role here. However, in general, what do you call your ISP as? A
'Heavy Inbound' or 'Mostly Inbound'? Is there any community standard about this
ratio (having 1:10 or higher) to be treated
Seems you just have updated today. Thanks for letting us know.
Last time, I checked was yesterday and based on that I mentioned your traffic
ratio being ‘Balanced’.

Thank you, Mike.
From an outsider, I don’t have any information of an ISP’s traffic numbers. And
this may be confidential unless we are using any measurement platform, which
CAIDA is doing. To get a rough idea about any ISP’s traffic outbound:inbound
ratio I can only see it's PeeringDB label.
Thank you Aaron for confirming that. This is helpful.

Indeed, it doesn't matter. The "traffic ratio" field in PeeringDB
probably should be deprecated, there is no formal definition nor is
are there any operational consequences
Josh,
That’s great. I’m assuming your traffic is mainly inbound. So, my question is,
do you have a threshold that defines your traffic ratio type.
I’m taking an example from this thread. Say, your average incoming traffic is
~45 gbps, and outgoing traffic is ~4.5 gbps. So, your outbound:inbound
Hi William,
Ha ha! Thanks for pointing that out. I’m not related to any ISP at all, so this
is something new. I understand, PeeringDB is just a basic guideline and ISPs
put their own information about their traffic ratios. I’m interested to know
whether ISPs check their own accumulated traffic
Hi Prasun,
It was updated because ‘Balanced’ wasn’t accurate, we didn’t notice that’s what
it said until you pointed it out, because it really don’t matter in the whole
