what the fuck
話説點解我HKBN會走咗去tata communication
我連去oracle cloud south korea可以200ms咁離譜
話説點解hkbn會有AS10103同AS9269兩隻ASN? 佢做咩要分upstream同downstream?
香港寬頻過咗咁耐都仲未整合 九倉 同 新世界電信 嘅 resource
之前同 HKBN 要 MetroE,人地個地址淨喺得九倉線,於是個 demarc 竟然唔同咗
我無得用我個 HKBN demarc 黎駁呢條線,會貴好多
未必係懶到狗嘅...本來佢地network team成個field咁做
佢地有得合嘅話,今年份成績表唔會柒左然後要瘋狂兜人
頭先打咗去hkbn qc team問個清 諗睇下點解oracle cloud south korea會走咗去tata
佢哋話呢個係oracle控制...個upstream佢哋個router覺得快就快...睇嚟要oracle人工干預
順便問佢哋點解家居寬頻仲未有ipv6 佢話點解要有 我問點解要冇
我話全世界都開始ipv6 deployment 但佢又攞pccw嚟反駁
話呢家ipv6啲peer都未齊根本上唔靚...
好...心服口服
我可以話用6rd或者tunnel broker玩一陣這 但係我真係頂唔q順he.net經常100ms爆炸
同埋我要/48嘅prefix assignment for calico同proxmox vm用
咁又其實諗真啲佢哋又未有權去broadcast ipv6 range畀所有人...
咁樣先可以eliminate single point of failure㗎
咁what 7 is single point of dailure
node多自然critieria咪多 flexible咁多點解會食屎?
Bgp learn route 特性,而且仲要peer
咁唔好shortest path咪得 改用a* heuristic
最多只可以話多node learn嘅時間耐啲,炒車範圍未必咁大
我會選擇預先learn多幾條做backup route
所以咪要learn多幾條然後用priority queue排
除非大家peer 都係30T 起跳,剩返嘅路夠食traffic
Traffic係咁多,水喉得咁大,自然jam同排隊,呢個無得走
所以一係分薄traffic 一係將啲水駁去其他水喉 一係水喉整大 一係水喉識自己節制...
唔記得咗bgp仲有convergence speed...好似係O(n^2)
至弊都係淨係support ipv4啲gear有沉沒成本...
你知道 v6 route 要佔 4 倍 TCAM space 嗎
optimize 咗用 trie 同 bloom filter 都要 2 倍 TCAM
即係一個 10M entries 嘅 TCAM 淨係可以塞 5M v6
論 route lookup cost 嘅話 v6 > v4
呢個 Juniper 用先,Cisco 而家Silicon One 都用
係 HKBN 自己唔 upgrade 啲 transit
而且ipv6相對亦都少好多range 因為容易滿足胃口
但係 ipv6 切碎嘅 potential 高過 v4
tcam memory
