Abstractions for Fault Tolerant Global Computing

Global computing (WAN programming, Internet programming) distinguishes itself from local computing (LAN computing) by the fact that it exposes some aspects of the network to the application, rather than seeking to hide them with network transparency, as in LAN programming. Global computing languages seek to provide useful abstractions for building applications in such environments. The lqp()-calculus is a family of programming languages that use the abstraction of logs to specify application-specific protocols for distributed agreement and fault tolerance in global applications. Reflecting the motivation for global computing, the abstraction of logs isolates the communication requirements of such protocols.
