This is an operator list. Not an opened research discussion. Take it off
the list.

We are not very familiar with the peer protocol,


Then pay an expert to teach you.


so we don’t know what questions can be discussed here or not. We are
researches, we just want to dig more to the cause of the slowdown that we
observed.


You know it is the GFW. Pointing to other places is baiting.  If you want
to know how China Telecom does business ask them. Not us.  If you want to
say it is not the GFW, then write a paper about it. Dont send emails here.

And we thought those questions are okay to ask here, which are not. But we
don’t want bait anyone.


It is not. Stop.


Sorry about the lack of knowledge of what can be discussed here.


Watch what others are talking about and add to it.  Nobody else here is
doing conversations like you.

Hi folks,

We got plenty of positive responses in our last email regarding China's
slow transnational network. Many are suggesting it is likely influenced by
commercial decisions instead of censorship. It seems like the three Chinese
ISPs don't really have enough peering internationally in Asia, and they
have very strong bargaining power when it comes to peering.

Some suggest the cost of moving data to China is way lower if an ISP
peers with US/European ISPs than directly with the Chinese ISPs. We assume
the reason why those US/European ISPs offer cheaper prices is that they
have settlement-free peering with Chinese ISPs. However, the "free-tier"
capacity is simply not enough to handle the demand -- the US/European ISPs
now have way more traffic going into China, thus saturating the link and
causing congestion.

So we are wondering, do the Tier-1 US/European ISPs really have
settlement-free peering with Chinese ISPs? If we want to do paid peering
directly with the Chinese ISPs or purchase the full/partial transit, what
is the price range?

From the BGP information, we know some of the peers of AS4134 (the
biggest one) are:
- Telia Carrier(AS1299)
- Cogent Communications(AS174)
- NTT Communications (America)(AS2914)
- Level3(AS3356)
- Tata Communications(America) Inc (AS6453)
- Verizon Business/UUnet(AS701)
- Zayo Bandwidth(AS6461)
- AT&T Services, Inc.(AS7018)
- GTT Communications Inc.(AS3257)
- Comcast Cable Communications, LLC(AS7922)

It would be much appreciated if the operators of any such networks can
give chime in. Thanks!
