Information Session on T2S User Connectivity Technical and Operational criteria for the selection of T2S Network Providers Silvio Orsini T2S Infrastructure Co-ordinator Frankfurt,14 July 2010 1
Disclaimer The following slides summarise the main aspects of the current considerations of the Eurosystem with respect to technical criteria on the basis of which the T2S Network Providers will be selected. Although some of the issues presented can be considered fairly stable and will most likely be part of the final decision, others are not, and might therefore be dropped or substantially altered. Consequently, these slides should by no means be used by any T2S Actor or potential T2S Network Provider to make any decisions or investments with respect to connectivity in T2S. Although this presentation has been delivered to a number of CSDs that have - together with the Eurosystem - signed the T2S Memorandum of Understanding, they have been published on the ECB website in order to give all economic actors equal and simultaneous information about the status of the T2S connectivity discussions. 2
Summary 1. Introduction 2. Volumetric assumptions 3. Selection criteria 4. Organization, operation and plan 3
1. Introduction The T2S platform The T2S platform widens over three Regions: Region 1 Italy Region 2 Germany Region 3 France The remote access to the platform is enabled by VANs Region 1 and region 2 are directly connected to the VANs Region 3 relies on the accesses to VANs at region 1 & 2 (using the internal 4CB network) 4
1. Introduction Responsibility T2S s responsibility ends at connection point P The network interface at T2S platform and user domain are technically decoupled How the user interface is defined is not specified by T2S Notary log middleware T2S platform domain P GW VAN VAN VAN U GW Users domain The gateway (GW) is the VAN termination-end under the VAN providers responsibility 5
1. Introduction Connectivity architecture The VANs are connected to the 4 sites avoiding any single point of failure The VANs take into account workload management and periodic swaps (i.e. rotation, recovery) Users do not perceive in which Region a module is running Rotation/recovery is transparent (no changes in user configuration is requested) T2S platform domain Site 1 Region 2 Region 1 Site 2 Site 3 Site 4 Gateway Gateway Gateway Gateway VAN domain network user domain T2S actor (user or application) 6
2. Volumetric assumptions Volume of transactions With reference to: T2S General Technical Specifications - General Technical Design version 2.2.0 7
2. Volumetric assumptions 2014 volume breakdown The following figures show the estimated volumes to be managed by T2S core system (the mainframe) and the archiving platform in the first year of production 8
2. Volumetric assumptions Network workload (2) Each VAN provider shall size its infrastructure based on its expected market share (theoretically it can also be equal to 100%) and shall size the infrastructure to ensure it meets performance and volume requirements Capacity planning breakdown data shall be provided to T2S administrator every year (for sizing and monitoring purpose) 9
3. Selection criteria The VAN services T2S connectivity services shall support file and message transfer, real-time (A2A) file and message transfer, store-and-forward (A2A) web access to T2S platform (U2A) 10
3. Selection criteria Message and file differentiation Message is a data structure containing a single financial instruction or information based on ISO20022 standard (maximum message length will be defined) File is a data structure containing two or more messages, (maximum message length will be defined) 11
3. Selection criteria Real-time file/message transfer T2S and Users are able to exchange messages and files A real-time message exchange (request-response) shall be completed within few seconds; If no response is received in this timeframe a timeout message shall be generated by the VAN and sent to the sender 12
3. Selection criteria Store and forward file/message transfer The sender can transmit message or file even when the receiver is not available The message/file is delivered by the VAN as soon as the receiver becomes available VAN shall provide to the sender a delivery notification failure after a maximum number of failed retries when the receiver is available after a number of days in case the receiver is not reachable 13
3. Selection criteria T2S Business Continuity support VANs shall support T2S Business continuity without any user intervention or impact on user configuration in case of intra-region recovery, between primary and secondary site in the same region, on request of 4CB staff, VANs are requested to switch the traffic in few minutes in case of inter-region recovery, between the two Regions, on request of 4CB staff, VANs are requested to switch the traffic in few minutes on periodic rotation occurrence (e.g. almost every six months), the VAN provider must switch the traffic between the two Region, on request of 4CB staff, during a week-end, in few minutes (planned operation) 14
3. Selection criteria Restart after disaster 1. Usage of VAN message retrieval service VANs resend instructions, settlement confirmations, static data changes, and maintenance instructions the same account positions can be rebuild with a reasonable likelihood (but no guarantee) 2. As an alternate option the users should resend messages and files the operational risk would significantly increase because of the needed interaction with many parties a huge co-ordination effort is needed in relation to testing message recovery 15
3. Selection criteria Recovery of the VAN The VAN shall automatically manage its recovery, exploiting the redundancies, to assure the service continuity T2S is not going to rotate in case of the regional disaster of a single VAN (users of that VAN will not be able access T2S platform) Recovery from one VAN to another is a user responsibility 16
3. Selection criteria Security features VAN shall provide the technical infrastructure to exchange messages in compliance with strict security requirements Confidentiality Integrity User identification and access control Non repudiation 4CB staff shall decide who is allowed to access the T2S domain monitor the technical operations at the T2S interface of the VAN manage all the encryption keys from T2S used in the VAN administer all the T2S credentials used by the T2S actors 17
4. Organization, operation and plan Service catalogue and manuals The VAN shall provide a catalogue of connectivity services for its customers as part of the T2S overall service catalogue Jointly with the 4CB staff, the VAN shall provide and maintain two reference manuals: Operations manual, that describes the network related components installed in the premises of the Service Provider and contains the complete list of monitored elements Escalation manual, that formalises the escalation process in normal and abnormal conditions 18
4. Organization, operation and plan Support and Incident/Problem management Support Team: the VAN providers shall offer to 4CB and the T2S actors a Service Desk service the 4CB Teams shall be able to contact the VAN providers Support Teams 24 hours seven days a week during all year Trouble ticketing system: the VAN providers shall record all actions, as well as the timestamp (time and date) at which the actions occur, in its central Trouble ticketing system this information shall be made available to the 4CB upon request and as part of the periodic incident review activity The VAN providers shall provide: initial response time for blocking problems: a maximum will be defined first status update time for blocking problems: a maximum will be defined 19
4. Organization, operation and plan Implementation requirements The VAN providers shall preliminary implement a proof of concept; the PoC infrastracture will remain as internal test environment for the 4CB (INTEG, IAC) The VAN providers shall support for implementing and executing integration and acceptance tests of the services 20
