Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 12 Network reliability The performance of the RMDCN over the last 12 months has been very good. The reliability of the network is high, having achieved 100% availability over most of the reporting period. The availability figures show the percentage of availability of a full operational service (without any incidents) (orange) and the percentage during which there were incidents that did not cause unavailability, since the backup was successfully activated (blue).

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 13 The future Important note The plans for the RMDCN next generation, as outlined here are subject to ECMWF’s Council approval (December 2011).

They would be reviewed by the ECMWF committees (Technical Advisory Committee and Finance Committee) in autumn 2011 and Council’s approval for the launch of an ITT in early 2012 would be sought at its 76 th session (December 2011).

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 19 Availability and SLA High availability is critical Guaranteed service levels – providers confidence Rebates – penalty; should reflect severity Local telco’s can provide 99.9%+ for access circuits GTTR ~4 hours; GTTF ~6 hours Service levels: – Providers core network – Connection to site (CPE, access circuit, PoP) Increase availability (up to 100%): add backup services (dual CPE, dual access line, …)

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 20 Technical aspects and Service Level Agreements Based on technical and financial considerations, five potential types of configuration have been identified and detailed here. They have been named: platinum, gold, silver, bronze and copper. This classification represents a generic model of service types for sites, which are differentiated by service elements such as type of access line, backup connection, service level agreement etc. It is envisaged to be used as a framework for the specification of requirements for the procurement of the future RMDCN service. Each site type will have its own Service Level Agreements. Note that the figures below regarding the SLA values are indicative only and may not reflect the actual values resulting from an ITT. During the ITT, the potential network providers will be invited to confirm which type of site they will support and what would be the associated SLA figures.

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 25 Typical connectivity architecture

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 26 Potential configurations and commitment to connect to the RMDCN During the preparation of their response to the ITT, the potential providers will base their commercial offer on, among other elements, the expected revenue they could get from the RMDCN. This revenue depends on the duration of the contract, the sites connected and the types (speed, SLA…) of configurations used. ECMWF plans to contact in the last quarter of 2011 all currently connected countries, in order to agree with them a list of “potential” configurations (e.g. up to five different options), and within that list a “preferred” one. This list of configurations should be as realistic as possible (that is, based on future requirements and available budget). The countries will also be invited to make a commitment regarding their connection to the future RMDCN. It is important that any request for quotes in the ITT, is reasonably close to the likely initial installation, both in terms of the specification of the configurations and of the countries involved.

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 27 Funding principles for the RMDCN When the RMDCN was first established, it was decided that each country should pay for its own connection. However, when the network was migrated from Frame-Relay to MPLS, it was decided that no country would see its charges increased as part of the transition. In order to do so, a mechanism for redistribution of charges was agreed. As the pricing structure from OBS may not be the same as the pricing structure from another provider, it is now impossible to guarantee that all prices for all countries will go down as part of the new ITT. Though recognising that an increase of cost will create an extra burden on some countries, and that they may decide not to join the RMDCN for this reason, the preferred option is to avoid any redistribution mechanism. By introducing up to 5 levels of configuration (Platinum, Gold, Silver, Bronze and Copper) it is hoped that each connected country will be able to select a solution that will be acceptable from both technical and financial aspects. The principle that every site should be responsible for the cost of its connections should be maintained and any redistribution of charges between the connected countries, in order to assist some countries with their financial obligations, should be avoided or limited to a minimum.

Past, present and future of the RMDCN – 02/11/11© ECMWFSlide 28 Envisaged contract duration The contract duration for managed data networks is generally around three to five years. However the situation of the RMDCN is very different compared to other companies contracting for networking services. The processes that need to be followed to procure a new network make it less flexible to change provider on short notice. Several arguments support the principle of 3-year cycle: – The lead time for a change of provider is around three years (this includes the whole procurement process and migration of the network). – Evolution in the market has lead in the past to significant cost reductions and chances for technology upgrades around every three years.
