Abstract
The MIT iLab Shared Architecture (ISA) is widely used to support remote experimentation, providing basic functionalities such as users management, scheduling, access control and results storage. This paper addresses the optimization of LabVIEW-based RE's creation under ISA, with the standardization of common lab server functionalities and communications. The Experiment Lab Server Architecture (ELSA), created as an ISA extension, fulfills the requirements of an ISA process agent and uses web services to connect the client with the lab server. ELSA automatically manages the initial definition and runtime traffic of experiment-specific input/output parameters. Once the experiment and client codes are created, RE configuration, startup and operation can be easily accomplished. In a pilot implementation using ELSA, the web services mediation of data transfer performed at rates high enough for a smooth user interaction experience. ELSA web services approach allows for a loose coupling in RE design and can effectively shorten its development cycle.
MIT iLab共享架构(ISA)被广泛用于支持远程实验，提供基本功能，如用户管理、调度、访问控制和结果存储。本文讨论了ISA下基于labview的RE创建的优化，以及通用实验室服务器功能和通信的标准化。作为ISA扩展创建的实验实验室服务器体系结构(ELSA)满足了ISA流程代理的需求，并使用web服务将客户机与实验室服务器连接起来。ELSA自动管理实验特定输入/输出参数的初始定义和运行时流量。一旦实验和客户端代码被创建，可重构配置，启动和操作可以很容易地完成。在使用ELSA的试验实现中，数据传输的web服务中介以足够高的速率执行，以获得平滑的用户交互体验。ELSA web服务方法允许RE设计中的松耦合，并且可以有效地缩短其开发周期。
