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: +----------------------MPBS box----------------------+ I +-----------------EMPP box-----------------+ I P11---o----I I----o---P21 .

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.

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."
