新加坡連去馬來點解要100ms

因為你窮

ok boomer

敵對國家

Check routing

第一步

跟住先投訴

發現原來係自己出街99ms

no, sgp vps -> malay

alicloud

馬拉係垃圾第三世界國家

完

route please

outdoor wait

Traceroute is the golden standard for diagnose network issues

onr of the hop is 70ms i remember

at day can be different

but this makes replication slow...

see

Check power on is the golden standard

The distance between Kuala Lumpur and Singapore is 316 km
speed of light = 0.00333564095 millisecond per kilometer
then theoretical max latency = 316 * 0.00333564095 = 1 ms..

.....你計緊啲乜野

無理由80ms架

啲router switch唔洗process time?未計佢係19

垃圾router...

係咁嫁啦，oversell overshit

U have money u go better lor

fuck alibaba

Convergence is needed, otherwise... U see fucked up

ah, so convergence is an optimization technique?

like dijkstra flow combine step

Simplify and save energy to serve jerk like u lol

im not doing anything illegal but just running disk replication

this malay instance is the bottleneck apparently

Wait and see lor. Nothing to do for such... Hmm you can pay more lor

時代冰室個大媽無咩禮貌，坐左好耐都落唔到單，佢話「等多陣得唔得」

話說點解新加坡去南韓要100ms

Shit node.

Traceroute will give u some information

Don't just talk the talk

theory first, practice second

...全部兜香港

國帘法

?

buffer 呢

你未考慮 congestion

因為 BGP 覺得近啲

cls去臺灣應該近啲喎

同埋去韓國經香港好正常

唔會

?!?!

你未考慮 graph degree

同埋實際啲海底電纜點行

oh 唔一定斜線嗎

....

香港個一點嘅 degree 高咁多

find im too naive

有人冇 follow 呢個 group

台灣冇海底電纜去韓國

呢個問題同啲人問點解架飛機唔直線飛去某地方，差唔多lv

利申無搭過飛機...

😂

No worry

會唔會有peer quality呢啲

新加坡 - 香港 - 韓國
新加坡 - 香港 - 台灣 - 韓國

新加坡 - 東京 - 韓國

Qos very last concern

點都係行香港合理

Unless they manually go

So, go to complain and complain la

咁有冇打過?

個 path 其實冇問題

最多係 return path 行咗東京

所以 90ms

我一直以爲latency就係triangular inequality咁簡單....

唔係

尋日先同你講完 BGP best path algorithm

...

i have goldfish memory...

其實純粹考慮 administrative distance

Bandwidth 同 latency 其實個 algorithm 冇考慮，係 infer 出嚟

所以成日要用 BGP attributes 人手微調

佢啲計數係得意嘅，好似佢嘅下個node就到韓國咁，一條dark fiber直到

就算係 dark fibre 可能都要係香港 patch 一次

睇下用乜嘢纜

唔係，佢個logic係一條fiber直線到

well...fuck...

咁似最近中國電信玩啲嘢

香港直線去法蘭克福

（物理直線）

咦咁hetnezer咪應該可以快啲

個條纜 只服務專線客戶

ah bugger

你可以買一條嚟自己搭 backbone

之前 WTT 未比 HKBN 買嘅時候有一條咁嘅嘢

157ms 香港 - 法蘭克福

呢啲野得不償失

賣得貴又無market

香港跟住直線去哈薩克斯坦

賣得平又回唔到本

哈薩克轉上去俄羅斯

跟住就直線去法蘭克福

係地圖上面差唔多係條直線

😂

係

不過呢啲歐亞陸地系統都比之前平咗好多

仲有 protection

哇 從馬來去新加坡回程經日本真係過份

因為你個 target 冇買 ntt transit

有嘅話應該 10ms 以下

jm9

this...is ridiculous

This is how BGP works

You minimise the administrative distance by more peering and transit

And not all transit works nice with your intended geographical area

台灣route去邊度最好🤔

台灣出發 睇下你目的地

通常都係香港東京美國

Not bad, not bad

唔錯 但係應該冇乜人買

呢啲數字目前得佢做到

留比出唔到國嘅人用
