Towards declarative abstraction for distributed programming

Stéphane Grumbach INRIA - LAMIA, Beijing

Programming network is a tedious task. High level abstractions have been proposed to facilitate programming and increase application portability and reliability.
In this talk, I will present a rule-based language, Netlog, to express distributed applications such as communication protocols or P2P applications in a declarative manner. The language extends Datalog with communication primitives, as well as aggregation and non-deterministic constructs, standard in networking applications.
Netlog admits a sound distributed fixpoint semantics, which takes explicitly into account the in-node behavior as well as the communication between nodes.
Netlog allows programming very concise code. The language runs over a virtual machine, Netquest, which relies on a DBMS, and is portable over any device which support a DBMS (eg, smart phones, PDA, iMote, network simulators, etc.).
Netlog has also been encoded in the Coq proof assistant, to verify the declarative protocols.
