Private and Public Peering

["HANSEN CHAN" <hansen.chan () alcatel com>]

Hi,

Can someone tell me the difference between private and public peering? A
peering paper I have read explained the switch is shared in the case of
shared and non-shared in the case of private. I still do not understand.
Appreciate if someone could shed some light on this matter for me.

My guess is that public peering is done in a commerical internet
exchange while private peering is done in a facility owned by either one
of the ISP.

Thanks,
Hansen
