Wes,
As I understand it, the bandwidth connecting the district to the K-20
network beyond the SSD is substantially less than what connects the district
facilities together within the WAN. We reach out from the district with a
total shared bandwidth of 6mbps while the bandwidth within the WAN is
considerably more. The server replication and authentication of users on the
Seattleschools domain should occur far faster then our connections to the
internet (I hope).
I drew a little diagram that crudely illustrates where the internet
congestion mainly occurs to and from the district. Check it out on the
following link.

Gee...Does that mean that there just might be a problem when we have all of
the office staff, teachers and kids logging onto the SeattleSchools domain
next year? If we can't keep up with SOME people using the Internet, how are
we going to keep up with EVERYONE in the district connecting to the
SeattleSchool domain?
