@zagfai 搞家宽就是另外一回事了，Last Miles 可没那么好弄

@CernetBoom 所有路由都是透过 DECIX New York 发给他们的

https://docs.nycmesh.net/networking/peering/

整张网的出口是一条 1G 的 DECIX New York，靠其他网络发全表给他们才能够被全球网络访问到

AS13030,AS27257,AS46450,AS54825 这四个目前在发全表给他们

@zhensjoke 你可以正价购买试试

@bclerdx 主要是渔业和抛锚

@bibiisme TPE S1S 是 TPE 上海到日本的一段，Telstra 用自己的 EAC-C2C，教育网的北京到洛杉矶就是用的 TPE(从青岛出的 S1N 段)

@hlz0812 那条就不是联通到 IIJ 的

@jousca 那你还说什么 BGP Hijack ？ ICMP 和 TCP 的路由都不一样，ICMP 的路由是正常的好吗？

所以 AS_PATH 呢？结果呢？

@bclerdx 219.158.102.201/219.158.102.202 挂了，然后剩下的流量全走那几条小的口子上去然后炸 Ping 丢包

@jousca 哈？ BGP Hijack 你 ICMP 还能通？

@yexm0 不止电信，联通移动 连科技网都是这样

@txydhr
A Paid Peering relationship is a peering relationship but with an exchange of compensation from one party to the other.

The compensation could take the form of $/Mbps as is the case with the more public offerings. In other cases it could be an asymmetric allocation of costs or the contribution of services of value.

Peering 和 Transit 又不是靠付不付钱区分的好吗

@txydhr N Flix 在美国就是找 Comcast 和 Verizon 买的 Paid Peering(不是 Transit)了解一下

@txydhr
Following an earlier post Peering into Peering , the definition of peering is settlement-free, "bill-and-keep," or "sender keeps all," meaning that neither party pays the other for the exchange of traffic.

Based on the definition, peering appears to be free of cost. However, that doesn ’ t mean peering is completely free. There are costs involved such as co-location, power, equipment (routers and switches), capacity, cross-connects, local loop, effort to manage the peering and so on.

@txydhr 那你解释一下 Paid Peering ？

@txydhr 费用指的是 Transit Fee 是可以理解的，Tier 1 的定义是 Transit-free(无 Transit/上游)而已，不可能不存在任何费用，XC 之类的也是要钱的，如果真的照你这个定义就没 Tier 1 ISP 了，Tier 1 和 Tier 2 ISP 直接也是可以直接 Peer 的，不需要买 Transit

@bclerdx Tier 1 就是 Transit-free network

@hlz0812 现在也有 31 的时候

@hlz0812 NTT 早上 3-7 点还正常
