MDNS requirements - letter to RARE defining EARN requirements

D Jennings

December 20,1989

The following letter, sent to Klaus Ullmann, is a statement of EARN's requirements for MDNS submitted to RARE. I trust it reasonably reflects the needs in each country.

14 December 1988

Mr. Klaus Ullmann,
RARE President,
DFN,
Verein,
Pariserstr. 44,
1000 Berlin 15.
 
Dear Klaus,
 
The  EARN  Executive Committee,  at its meeting in Paris  on  8/9
December 1988,  considered and approved the participation of EARN
in the proposed MDNS Pilot Project.  The EARN Executive Committee
reviewed  EARN's  requirements for the MDNS Pilot and agreed  the
statement of requirements given below.   This statement  confirms
and  extends  the statements already provided  electronically  by
EARN.   It should be carefully noted that EARN's participation in
the  MDNS pilot is not a commitment to use the MDNS Service after
the  Pilot  Phase,  since  the decision to use  the  future  MDNS
Service  will  depend on the outcome of the  Pilot,  and  on  the
detailed plans for the MDNS Service.
 
EARN's Requirements for the MDNS Pilot Project:
 
General Requirements:
 
1.   That  EARN  participates  fully  in  the  planning,  project
     management, and evaluation of the MDNS Pilot;
 
2.   That  the  MDNS Pilot service offering is complementary  to,
     or  enhances,  EARN's existing and planned services to  its
     users;
 
3.   That the full cost of EARN's participation in the MDNS Pilot
     is  covered by project funds  (including  travel,  manpower,
     equipment, communications lines, etc.);
 
4.   That  the  MDNS  Pilot takes EARN's  technical  requirements
     (e.g.   addressing  schemes,  protocols,  etc.)  fully  into
     account;
 
5.   That the MDNS pilot provides access to the PPSDN's for  EARN
     hosts and to/from the EARN X.25 backbone;
 
6.   That X.75 access be provided between the MDNS Pilot  Network
     and the EARN X.25 backbone, and that the MDNS Project assist
     EARN  in  obtaining  a  recognised DNIC for  the  EARN  X.25
     backbone;
 
7.   That the quality of service measures for the MDNS be defined
     and  agreed with EARN as part of the MDNS  Pilot,  and  that
     service quality is rigorously measured as part of the Pilot;
 
8.   That   the  MDNS  Pilot  Project  addresses  the  legal  and
     regulatory  issues already identified,  and any others  that
     arise  during  the project.   These  include,  for  example,
     tariffs  for communication from PPSDN's to PPSDN's  via  the
     MDNS Pilot network or the EARN X.25 backbone; access control
     to  ensure that traffic into the EARN network from the  MDNS
     Pilot network meets EARN's regulations; etc.;
 
9.   That  EARN  participates  fully in the  MDNS  Pilot  Project
     Steering  Committee,  and  that this Steering Committee  has
     control of the project, as agreed at the RARE COA meeting on
     2 December 1988;
 
10.  That  traffic  from  EARN countries  which  are  not  COSINE
     countries be allowed on the MDNS Pilot Network.
 
Specific Requirements:
 
At  present  our  best  estimate  of EARN  needs  in  the  COSINE
countries  is  that the MDNS Pilot Network  provides  connections
from  the  national  MDNS  access points to  the  following  EARN
international  nodes,  in  the  manner  and  with  the  bandwidth
indicated,  and that all costs of lines and modems be met by  the
MDNS pilot project;

T.B.D. - to be determined
 
 
These  specific requirements should already have been  identified
by  the RARE COA members,  in consultation with the national EARN
Directors, when identifying the national  requirements for use of
the MDNS Pilot Network.
 
Initial Requirements for the MDNS Service Network:
 
In  addition to the general requirements for participation in the
MDNS   Pilot   Network,   EARN  has  initial   requirements   for
participation in any future MDNS Service Network:
 
1.   That the quality of service levels agreed for the MDNS Pilot
     have been achieved at least three months before the start of
     the MDNS Service Network;
 
2.   That  the  full costs of participation in the  MDNS  Service
     Network  are identified and published at least three  months
     before the start of the MDNS Service network;
 
3.   If any support to the MDNS Service Network is provided (e.g.
     by the CEC,  COSINE, etc.) that the complete financial model
     covering  levels  and duration of funding  be  published  at
     least  three  months  before the planned start of  the  MDNS
     Service Network.
 
I trust that EARN's requirements for the MDNS Pilot will be fully
incorporated  into the plans for the MDNS,  as agreed at the  COA
meeting  on 2 December 1988.   I regret that the  EARN  Executive
meeting  could  not  have  been held  earlier  to  confirm  these
requirements,  but it was not possible to change the arrangements
already made.
 
With many thanks,
 
Yours sincerely,
