THE ROLE OF DCE TO MANAGE COMPLEX NETWORKS

摘要

Open Software Foundation's (OSF) Distributed Computing Environment (DCE) is an integrated distributed computing environment based on open systems.It is a heterogeneous distributed environment consisting of software and hardware from different vendors.DCE is the recult of extensive collaboration among private industry,academic and research institutions.It contains a distillation of much of the best distributed computing technology currently available.It provides a distributed infrastructure and API to develop,use,and maintain distributed applications and is currently being deployed on a la.ge number of heterogeneous platforms.The technology embodied in DCE is significant and covcrs several areas such as security and administration which are important in a networkec environment.DCE deployment has begun to move from small prootype cells withn leading edge adopters of technology to use as a pleat rm for enterprise wide mission critical distnbutud applications. Several telecommunications related companies (both telco services and telco equipment providers) have been at the forefront of DCE usage.This paper describes how DCE is beihg used in networked environments.DCE consists of a number of ub-systems and services,some of which are:remote procedure call,directory services,distributed time services,security service, distributed file services and management services.DCE functions will contribute to the enhancement of future network architectures.
