摘要

RPC被广泛用于访问和修改远程状态。它的过程调用语义被认为是本地和远程访问的有效统一范式。我们对无处不在的设备控制系统的经验却证明了这一点。静态类型接口上的同步、阻塞调用的RPC语义过于严格、不灵活，并且无法为访问和修改无处不在的系统中的状态提供有效的统一抽象。本文考虑了其他替代方案，并建议使用comvets(有条件的、移动感知的事件)作为此类系统的统一通用通信范式。

Communication primitives for ubiquitous systems or RPC considered harmful

RPC is widely used to access and modify remote state. Its procedural call semantics are argued as an efficient unifying paradigm for both local and remote access. Our experience with ubiquitous device control systems has shown otherwise. RPC semantics of a synchronous, blocking invocation on a statically typed interface are overly restrictive, inflexible, and fail to provide an efficient unifying abstraction for accessing and modifying state in ubiquitous systems. This paper considers other alternatives and proposes the use of comvets (conditional, mobility aware events) as the unifying generic communication paradigm for such systems.
