Abstract
We elaborate on previous work in which we presented SeB, a formalised subset of BPEL extended to support session-based interaction. Sessions are endowed with types that prescribe the correct structure of interactions, and a typed system can be checked for interaction safety. In our previous approach, the communication model was based on reliable FIFO channels, an arguably strong assumption. In this paper, we remove these assumptions and adopt an unreliable and unordered communication model. The contributions of the paper are threefold. Firstly, we propose a model for unordered lossy communication for long-running service interactions. Secondly, we study the effect of this new model on service development, and extend the SeB language and semantics to support message loss and disordering. Finally, we make changes to the session typing system such that our typing discipline now allows us evaluate the interaction-safety of a service configuration in which messages can be lost or arrive in the wrong order.

Two transitions leaving the same state are said to be confluent if the choice of executing one of them leads to a state where the other transition is still executable in some future state.
