Greetings:

Can someone enlightnen me?  Can Linux OS be used in a network manangement
since?
For example can you use it like for HP Openview or Cisco Works? Or is there
an equal open source program that can monitor things like routers, switches,
leased circuits, bandwidth, etc?

I am trying to understand the conversation about caching too. Please help?
