[edit] Technology
JPNAP has two distinguishing feature : one is "Automatically switched optical patch panel" and another is "PeerWatcher".
When "Automatically switched optical patch panel" finds IX switch's failure, it switches patch cable to the other IX switch automatically. Even if the patch panel has power problem, it's no effect for the communication except detecting IX switch status.
"PeerWatcher" shows traffic graph between two BGP routers faced on JPNAP network using sFlow.
