Oskar Sandberg:
I still don`t understand where you see Multicasting being used? That
messages are sent to one node at a time is central to Freenet,
duplicating searches by sending them to many places is completely
contrary to what we are trying to achieve.
I'm glad you asked, I have been meaning to explain that.
I see multicast as being strictly a local-area feature. Essentially,
it's a way for a set of machines of a single building or campus to share
their data stores: When a node gets a request for an item, it multicasts
to the nearby hosts to see if it can get a quick response before it
forwards the request off to the never-never-land of western metropolitan
Portland, Oregon. If a receiver of the local multicast has the data, it
sends the data to the multicaster.
As for how that affects the routing -- it's hard to say. Still need
that simulator...
