DWDM Mux, no need DWDM transporter
You still need ROADM to create more flexible topology
No need la, buy a Mux, and buy some DWDM SFP+ then OK
我玩FSO仲 high tech , 叫space-x ship粒星做 FSO reperater
10000V @ 0.1A 左右啦，實際比幾多電要睇條纜 config
但係無咗中間放大機嘅 maintainance cost
因為bandwidth 細到屌左聲，align 好煩
Ofta 出過 Wireless Fix Network 牌
不過宜家 Optics 嘅方向係降低光纖嘅 IOR
但要過完fiber再過fiberless tune死人
總知有幾多share幾多，headend可能得1G
OLT 有幾十 G，一條 GPON 2.5G/1.25G
Splitter 嘅話就係 10G/2.5G 咁分
哈，128戶 share 10G, 仲要睇 Telco 間間 setting
XGPON2 升到 10G Symmetrical
咪住 佢個隻 XGPON OLT 支援 WDM PON……
但D人唔知GPON 係 shared base, 仲日日玩 speedtest
雖然咁大間 HKT 應該有 team 人識得 main 嗰啲嘢
一個port開256，一張卡8定16port,可以插10定16張卡，一個cabinet3個shelf
點解GPON 通常install 白色Fiber?
同 yellow single mode fibre 差D 嗎?
G.657.A1 (Compatible with G.652)
OS1 同 OS2 都係黃色，但係 OS2 幼身啲
過樓上百米呢啲一係 singlemode 一係 OM3
Cisco Certified International Sex Partner?
原來咁簡單

Port 1-10 VLAN 100
Port 11-20 VLAN 200
If only 1 router and 1 switch
佢個部 3560G 喺 Layer3 Switch
int ra gi0/1-10
switchport access vlan 100
int ra gi0/11-20
我見網上有D tutorial係講完switch先再講routing
I have your password and ip
我地係Site to site線連返main campus再去其他campus
然而得10Mbps
Domain Login都係塞死係個10Mbps
PP1# interface fa0/45
switchport mode trunk
隻firewall block左佢段subnet出街
Because Packet Tracer have unlimited money
unlimited funds to build network
點樣係有限既budget起一個符合公司situation嘅network
My Virtual Company network
係packet tracer sim出黎?
咁現實呢
Pure L2 inter-Office network
1 Router to serve 5 sub-office
Etherchannel over Etherchannel is it possible ?
Sorry, what is SE intern job ?
dedicated host is too expensive since it cannot oversell
kvm is still expensive...cant oversell cpu
(unless it is hyperthread)
lxc已經merge咗入linux kernel好耐
嚴格上嚟講唔係vps...係chroot jail on steroid
其實如果得一隻router,(default) static route set 0.0.0.0 255.255.255.255 ROUTER_IP 係咪OK
Novell 有自己的協議。你可以在windows add
