海缆不堵,线路看对接运营商

海缆没有什么堵不堵的,你买多少波就是多少波,堵的只是你的骨干网,TPE 什么的照样还一堆没点亮

联通到 ijj 现在很稳 波动不会超过 10ms

@tia iij 延迟是稳,但是高峰期丢包严重,速度貌似可以跑的起来,G 口的 iij 晚上到联通多线程跑 150M 左右

@bclerdx iij 卖给不同 idc 的貌似优先级也不一样,同样走 iij 的也有的快有的慢,联通到韩国的线路比较好,韩国三家的线路联通高峰期也不慢

bclerdx OP @hlz0812 目前似乎还是中国电信走上海或北京的出口到日本或美国 NTT 的线路各种丢包,走 HK NTT 的线路会好些吧?
|
14
bclerdx OP @hlz0812 完了,刚测了一些,中国电信走广州、北京出口的到日本东京炸了,走上海电信到 NTT 的到是很正常。。联通线路走 HK NTT 一切正常。

@bclerdx 你得换 cn2 才能走那个点,上海 ntt 连 20Mbps 都跑不到,IIJ 这种爆炸线路刚测了下到电信都能 270 多 Mbps
|

bclerdx OP @hlz0812 可问题的关键就是丢包啊,丢的厉害。我受不了了(电信 与 NTT 之间),已经吐槽给 NTT 那边了,看看反馈结果吧。

@bclerdx 4134 没有 2914 在香港的互联,和 9293 完全是两个东西,首先你得是 NTT 的客户,其次要是这样有用那 NTT N 年前就扩容了

hlz0812 2019-08-01 21:47:06 +08:00
@bclerdx 走 ntt 的线路挂代理,然后在国内电脑上跑 speedtest,7-10Mbps 左右。这个已经是极限带宽了,看视频的话几乎就 50KB/s,本地 1000M 宽带

bclerdx OP @CernetBoom 为什么是 NTT 不扩容,而不是 AS4134 不扩容呢?

@txydhr 电信亚太地区不管你 t 几都是收费,欧美才有免费的,pccw 也是 t1,亚洲带宽还不是要买电信的,所以 pccw,telstra 什么的都把直连带宽拿来卖,不然给你绕美国的 free peer 去

bclerdx OP @hlz0812 不是说延迟高,速度照样跑起来嘛,只要不丢包就行。中国电信摆什么臭架子啊。联通就很好呀。

hlz0812 2019-08-02 19:25:04 +08:00
@bclerdx 关键是免费的口子就那么大,而且免费接口上的用户量还远远大于收费端口的用户量,根本不可能快的起来。像那种买了电信 20G 以上带宽的 IDC 或者运营商,往电信高峰期都可以跑 300Mbps 以上。Tier1 运营商高峰期到电信基本都是堵死的,除了 pccw 这种买的带宽比较多,而且还不低价卖给 IDC 的,像 cogent、telia、level3 这种的哪个不堵?这些 Tier1 运营商下游客户太多了,他们到中国的带宽根本支撑不住那么多流量。说真的只要不是烂大街的线路,到中国就算只有 10G 体验都不差。
电信到 IIJ 10G,联通到 IIJ 10G 电信到 softbank 40G,联通估计 30G 的样子,KDDI 应该也差不多 |

@CernetBoom telia 带宽虽然不少,有时候回程走 telia 的机房多了还是堵,基本上就是那几家大的 idc 把路由调哪家回程哪家就炸。IIJ 白天还好,ntt 是 24 小时堵,我都怀疑是不是故意搞成这样了,半夜 3 点起来看也是那个水平

@CernetBoom
A Tier 1 network is an Internet Protocol (IP) network that can reach every other network on the Internet solely via settlement-free interconnection (also known as settlement-free peering). Tier 1 networks can exchange traffic with other Tier 1 networks without having to pay any fees for the exchange of traffic in either direction, while some Tier 2 networks and all Tier 3 networks must pay to transmit traffic on other networks. 不是不应该付钱么 |

CernetBoom 2019-08-03 01:46:46 +08:00 via Android
@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
|

txydhr 2019-08-03 04:07:42 +08:00
@CernetBoom The pure definition of peering is settlement-free, also known as "bill-and-keep," or "sender keeps all," meaning that neither party pays the other in association with the exchange of traffic; instead, each derives and retains revenue from its own customers.

@txydhr 那你解释一下 Paid Peering ?

CernetBoom 2019-08-03 07:46:58 +08:00 via Android
@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 N Flix 在美国就是找 Comcast 和 Verizon 买的 Paid Peering(不是 Transit)了解一下

@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 |
