RxTender is built on the following ideas:

• An IDL is used to specify reactive streams.
• There is a clear separation between:
  • transport
  • framing
  • serialization
  • stream definition
• It is possible to generate source and sink streams.
• It is easy to add support for new programming languages, serialization and framing protocols.
• The transport layer is not managed by RxTenders.

These ideas are summarized on the following figure showing a typical usage of RxTender where two services communicate with a reactive stream:
