Explicit Connection Actions in Multiparty Session Types
[chapter]
2017
Lecture Notes in Computer Science
Preserved Fulltext
This work extends asynchronous multiparty session types (MPST) with explicit connection actions to support protocols with optional and dynamic participants. ...
In addition, the use cases motivating explicit connections often require a more relaxed form of multiparty choice: these extensions do not satisfy the conservative restrictions used to ensure safety in ...
