There are 8 new ISDN lines.
Second Agenda Item: Action Items
A. Price List of Existing Central Site Hardware
This does not represent a plan, rather it's a description of
what is in use.
Server
Preferred platform is a Pentium PC. After comparing a couple of different PC "brands" we have settled on the DEC Celebris. Other brands we have looked at include: Gateway, Vecktron and Leading Edge.

B. Network Topologies for Fall of 1995
Connectivity Summary
Dial-up: Spring Hill, Ft. Pitt, McCleary
LADS: Woolslair, Liberty, Frick, Schenley, Admin
Building
ISDN: East Hills, Phillips, Westinghouse, Carrick,
Fultonh, Fultonj, Knoxville, Schiller, Allegheny
Central Site is supported by two servers - oberon and titania.
Discussion
As of yet, we have not hit a saturation point with
regards to connectivity.
Do not have data projecting what load on existing lines
will be.
Also do not have data on where the bottle-necks in the
system will be.
Some of this data will be available at the end of this
school year, because this is the first year with 14 servers.
Before the 95-96 school-year, only 4 servers were in active operation.
It looks like 28,800 and 56K lines could get saturated.
We will have data on these sites by the end of the school-year.
Teacher and student use determines load on the school
server.
ISDN can do incremental upgrades.
Third Agenda Item: Develop Preliminary Design of
Central Site Architecture
Following last meeting, there was a preliminary agreement
that:
-the PPS central site would support 2 servers. One for accounts and one for network services. The issue of security was brought up, but not elaborated on with regards to server deployment.
Myron asked the group to review the proposal from UNISYS
as a way of broadening the present discussion. He asked the
group to comment on whether the UNISYS plan is a viable
route. One of the reasons to look at the proposal is to
consider if it offers a "turn-key" solution to central
architecture. The issue of interoperability was brought up,
with the idea that it needed to be an item of consideration
in reviewing the UNISYS proposal. The proposal presents an
integrated system. CK:P also uses an integrated system. The
review process will offer the opportunity to do some
comparisons.
The group agreed to review the UNISYS proposal from the
following vantage points:
-Interoperability with Network Packages
(protocol, clients, servers, must support Web,
gopher, news, file-sharing, LAN and MAN architecture)
-Full Internet Access is the beginning point
(firewalls and security considerations will need a
broader audience - PPS policy groups)
-Flexibility of Access
-Support
Items For Next Meeting
1. Draft requirements for Central Site
2. Review and comment on UNISYS proposal
3. Straw-man CK:P in-house plan (server, clients and
network components)
