Specializing Object-Oriented RPC for Functionality and Performance
نویسنده
چکیده
Remote procedure call (RPC) integrates distributed processing with conventional programming languages. However, traditional RPC lacks support for forms of communication such as datagrams, multicast, and streams that fall outside the strict request-response model. Emerging applications such as Distributed Interactive Simulation (DIS) and Internet video require scalable, reliable, and efficient communication. Applications are often forced to meet these requirements by resorting to the errorprone ad-hoc message-based programming that characterized applications prior to the introduction of RPC. In this paper, we describe an object-oriented RPC system that supports specialization for functionality and performance, allowingapplications to modify and tune the RPC system to meet individual requirements. Our experiences with functional extensions to support reliable multicast and specializations to support streaming of performance-critical RPCs indicate that a wide range of communication semantics can be supported without resorting to ad-hoc messaging protocols.

RPC has established itself as one of the more powerful communication paradigms for distributed computing. In recent years, object-oriented languages have impacted RPC semantics, with a number of variants providing remote method invocation and various forms of distributed object systems. At the same time, performance has changed little with the bottleneck being the network transport, in particul...

متن کاملDC++: distributed object-oriented system support on top of OSF DCE
The OSF Distributed Computing Environment (DCE) is becoming an industry standard for open distributed computing. However, DCE only supports client/server-style applications based on the remote procedure call (RPC) communication model. This paper describes the design and implementation of an extended distributed object-oriented environment, DC++, on top of DCE. As opposed to RPC, it supports a u...
