  1. REUTERS / FirstnameLastname Thomson Reuters Contributions Channel David.M.Thomas Developer Advocate - Platform APIs

  2. The Contributions Channel Overview A New service allows clients to contribute content on the Elektron Network Hosting a cluster of servers that provides the Contributions logic previously placed at the client site All contributors (TREP, Contex and 3rd Party) will connect to this new service

  3. 3rd Party Application Integration • Clients and solution providers can develop contribution applications using the Elektron APIs : • Outputs are connected directly to the new Contributions Channel • Uses Elektron SDK tunnel stream connections • Uses OMM Post Messages • Supports MarketPrice Model • Credentials will be authenticated against our AAA platform

  4. Tunnel Streams EMA/ETAProvider EMA/ETA Consumer • Available in the ETA Reactor and EMA • A tunnel stream is a private stream with authentication • Establishes a connection between Application and Contribution Gateway • Allows multiple sub-streams to co-exist within the tunnel stream. • Contributions are made using sub-streams

  5. Contributions Topology Contributions Service Gateway Contribution Channel Service Cluster Delivery Direct Or Internet Encrypted TLS over WAN 3rd Party App Elektron API

  6. Benefits Removes the need for client sited contributions only server devices Provides a higher level of performance than Marketlink Provides a simpler contribution solution that is consistent with TREP publishing Uses strategic Elektron APIs rather than MFOT Use of Open Message Model will allow the contribution of more complex data types

  7. Demonstration: Contributions Application • Using EMA Java from the Elektron SDK • Establish an encrypted connection to the server • Create an OmmConsumer configured as "ChannelType::RSSL_ENCRYPTED" • Make a TunnelStreamRequest request. • Response: StatusMsg with StreamState = Openindicates the Tunnel Stream is open.

  8. Demonstration: Contributions Application • Perform a client login: • Supply user name and password credentials. • Response: RefreshMsg with StreamState = Open • Contribute data using post messages • Response: AckMsg • An AckMsg provides an indication that the contribution was received by the service. • If the AckMsg contains a NackCode then the contribution failed

  9. Example PostMsg
