Report to the OU shareholder meeting on the EBONE integration scenario
======================================================================
I. Task: The OU Steering Committee (OUSC) had the task to identify an
------- integration scenario for the IP service which is presently
been organised under the name EBONE. During that discussion
a statement from th EBONE management committee has been sent
to the OUSC (see annex 2).
This document describes a possible scenario to incorporate
EBONE in the OU Business Plan. The General Assembly is asked
to decide upon this scenario as the answer to the statement of
the EBONE management committee.
II. External Material Used:
--------------------------
1) Ebone Line and Site Installation Specification
Ebone Action Team (B.Stockman); 24 February 1992;
2) Management and Operation of the Ebone
B.Stockman; 13 April 1992;
3) Ebone '92 IP Routing Model
T.Bates, P.Lothberg; June 1992.
While 1) gives an overview on the technical details, 2) deals with
operational management procedures and 3) indicates the construction
principles of the Ebone configuration.
In addition to this material facts and figures about Ebone have
been supplied by several members of the Ebone Management Committee
(Dennis Jennings and Kees Neggers). These figures are the basis of
the cost analysis described in Annex 1.
III. Results:
------------
2. General OU Multiprotocol Service
It is proposed that the OU should in the context of the Multiprotocol
Backbone Service (MPBS) offer three different types of access:
a) native X.25 (through access points P1i, i=1,2,3...; see fig.1);
b) native IP - pilot version through EMPP (through access points
P2i, i=1,2,3...);
c) native IP - through the existing Ebone structure (through access
points P3i, i=1,2,3...).
The commercial conditions for P1i and P2i are described in the
umbrella contract between PTT Telecom and -at present- RARE.
Both IP offerings are connected via two interface boxes (IF1 and
IF2); the whole MPBS of the OU can then be viewed in the following
way:

After an initial period the OU will base its IP service offering on
one system, and it will take the results of the EMPP evaluation
into account in its choice of system.
Until that moment customers are free to choose which IP services
they want to buy, EMPP and/or Ebone.
3. Organisational Structure
The OU will sell the IP service based on EBONE (P3i) to customers
on a contractual basis. That implies towards the customers that
the EBONE system is exactly specified in advance and can only be
changed in agreement with the parties affected by these changes.
The OU will subcontract suppliers of lines and sites that houses
and manages Ebone Boundary Systems (EBS). It is recommended to keep
these contractual relations as light weight as possible as far as
a) the formal relation between the OU and the EBS sites
respectively,
b) the OU and the organisations responsible for the lines,
c) the OU and the organisation that employs the operational staff
are concerned.
It is assumed that operational procedures are taken from existing
descriptions.
4. Quality of Service Guarantees
It is recognized that the service provided through the Ebone
structure has no well defined quality of service parameters and
there are no guarantees for which the customer of the OU can make
responsible either the OU or one EBS site or one organisation in
charge of line provision or provision of operational staff.
The Ebone consortium will be invited to describe on short term the
present service levels as good as possible in order to allow the
OU management to define the actions required to maintain these
service levels.
5. Cost Analysis and Tariffs
In Annex 1 a model is presented describing the present Ebone box in
terms of backbone lines, gateways, access lines, equipment and
staff; all based on a number of assumptions. These assumptions have
been communicated with some members of the Ebone Management
Committee but not yet with the other participants in Ebone. For
that reason these assumptions have a preliminary character.
The model is more or less the same as the model used for the OU
business case. After the assumptions it is built up in three parts:
the requested access services from the customers, the costs of the
services and the allocation of costs (tariffs). The methodology
used for the allocation of costs is equivalent with the one used in
the RARE- PTT Telecom contract for the EMPP box.
The tariffs for the IP services provided through the EMPP- and
Ebone structures are different and not cross-subsidized.
A warning has to be made that it is not possible to make a straight
comparison in terms of price and performance between EMPP IP
services and Ebone IP services due to the lack of service level
guarantees within Ebone.
6. Customer Base
The OU will accept present Ebone customers as customers of the OU
provided that:
a - the purpose and usage of the connection is in line with the OU
mission statement and
b - no third party traffic, neither international nor national, is
allowed without written permission from the OU management.
6. Migration
After an initial period the OU will base its IP service offering on
one system. This initial period will end as soon as this intended
single systeem has demonstrated its operational capabilities and is
able to supply the customers with the same or better services
against the same or better prices. After this initial period the OU
management will decide upon the migration scenario. The costs for
the migration from the Ebone to the final MPBS production phase are
seen as transition costs which has to be covered by a (special) OU
budget line. These costs comprise for example parallel lines etc.
It must be possible to cancel lines at the shortest possible time;
i.e. Ebone backbone and access lines have to be based on contracts
for an initial period of at most one year with a cancellation
period afterwards of at most three months.
7. Clearing of Costs
Based on the cost allocation scheme in Annex 1 the OU will invoice
in advance on a quarterly basis the Ebone customers for who the
tariff is higher than the total of accepted costs. The OU will
reimburse in the second month of the actual quarter the Ebone
customers for who the tariff is lower than the total of the
accepted costs. Based on this clearing method the working capital
needed by the OU to accept the commercial responsibility for the
Ebone services will not exceed 200 KECU.

Annex 2: Statement EBONE MC
---------------------------
The Operational Unit Steering Committee received in July 1992 the
following message from the Ebone Management Committee:
" The Ebone MC has addressed the continuation of the Ebone '92 IP
service for 1993. Ebone MC has noted the plans and progress in
setting up the OU and the OU's intention to provide a pan-European
multi-protocol backbone service. Ebone MC has concluded that to be
able to secure a proper continuation of IP backbone services in
Europe it will be necessary to continue the current IP services at
least until mid 1993. The Ebone MC is keen on optimising the
transition process from the current situation to a single
pan-European multi-protocol backbone service and on minimising the
organisational overhead involved. Therefore, the Ebone MC offers to
propose to the Ebone participants that the Operational Unit takes
up full organisational and commercial control over the Ebone '93 IP
services as soon as possible. This proposal is conditional to the
OU being prepared to continue the operation of the Ebone IP
technical infrastructure until the intended MPBS has demonstrated
its operational capabilities to replace it."
