COSINE SPECIFICATION PHASE

PROPOSAL FOR STUDY

TITLE: Migration from X.25(80) to X.25(84) in COSINE

The Computing Service proposes to perform the study on the Migration by the 
PTTs from X.25(1980) to X.25 (1984).

The person in overall control of the study would be Brian Gilmore and the actual
work would be carried out by George Howat and Bill Byers.

The  Edinburgh  University  Computing  Service  (formerly the Edinburgh Regional
Computing Centre) is well equipped to carry out such a study; it has constructed
and managed a sizeable local X.25 network for a number of years.   This  network
has  included a private gateway to the British Public X.25 network thus ensuring
a close knowledge of PTT practices.   The EUCS has been  closely  involved  with
the  Joint  Network  Team,  having  completed  two  surveys  of  X.25 networking
equipment in the past 2 years, these  surveys  included  a  need  to  check  the
conformance  of  manufacturers equipment to British PTT standards.   In addition
the above individuals have been closely concerned with the X.25 protocols having
recently completed a major implementation of the X.25  (1984)  protocols  for  a
number of Unix machines, PADs and Gateways.

Timescales

The elapsed time to complete the report after notification of acceptance will 
be 12 weeks.

The Report

The  structure  of  the  report  will  follow  the  guidelines  laid down in the
'Request for Proposals' document with each item being addressed.

Restrictions

In  the  time  available,  it may not be possible to establish the proposals for
migration of each of the European PTTs, it is  therefore  proposed  to  approach
CEPT for the common position and then to verify the actual plans with as many of
the major European PTTs as possible.

Effort Required

The estimated joint effort for the study is 3 person weeks.   The rate  per  day
for  the  staff  concerned  is  206  pound sterling.   The total staff costs are
therfore 3090 pounds sterling.   In addition to this is an estimated  100  pouns
sterling for telephone calls, giving a total of 3190 pounds sterling.
