This is kind of long, but I was wondering if we should inform the team
of our efforts, so that they can plan along with us??? (Why duplicate
efforts if we can work together at a viable solution)...

The following is a scope statement for an short-term effort relating to
provision of Athena services over 56KB network links to the Independent
Living Groups.
By September of 1993 all MIT independent living groups will have
connectivity to MITnet as part of the Resnet effort. Standard connectivity
for off-campus living groups will be a 56KB connection using New England
Telephone's frame relay service. Beginning this fall we expect each ILG to
connect some number of Mac, DOS/Windows, or other workstations to its
network. We also expect that ILGs may want to acquire one or more Athena
workstations in order to gain access to the full services of the Athena
Computing Environment from their residences. Preliminary testing using a
56KB line in the E40 test cluster has indicated that standard Athena
workstations may experience signficant performance problems running over
56KB links.
Acceptable solutions to this problem must deal with several constraints.
First, students are very conscious of costs. Therefore low-cost solutions
to this problem are preferred. Second, development staff resources are
very tight this summer due to other major committments and to unfilled
positions and so solutions that do not require significant staff time to
implement are also preferred. Third, optimal solution(s) will not place
significant on-going demand on operations or consulting staff. Finally, a
solution must be in place and documented by mid-August when students begin
to return to campus.
The scope of this project is to:
-determine what options there are in the near term to improve the
performance of Athena workstations running over 56KB links to "acceptable"
levels
-recommend, implement, and document one or more solutions that
balance the goal of acceptable service with the reality of limited staff
resources and limited student $$$
-verify the solution through appropriate testing
-produce a document that communicates the level of service that students
should expect to see if they run Athena workstations over these 56KB links
with this solution as well as any recommended limits on the number of such
workstations that should be installed per site
-communicate the solution(s) to front-line IS groups (MCC, Consulting,
Hotline, etc.)
Richard Basch (basch@mit.edu) of DCNS and Christina DeMello
(cdemello@mit.edu) of CSS will be responsible for this effort. They will
communicate about their work with the Technical Review Board,
resnet-planning group, and the Athena Consulting, and MCC staff as this
effort proceeds.
