To solve the problem of complex,cumbersome and error-prone configuration of security devices caused by the heterogeneous configuration modes in complex networks,a dynamic template-based scheme for translating and configuring policy was proposed.In detail,considering the code’s features,the code-based template for translating policies was constructed to configure the command line conversion,and the keyword comparison method was used to ensure the accuracy of policy configuration.Experiments show that the scalability and the accuracy of the proposed scheme. 相似文献

A programmable data acquisition and control system was developed for use in conjunction with magnetic resonance imaging (MRI). The controller consists of two functional blocks: a host system and a remote system. The remote system resides inside the shielded room housing the magnet. The host, an IBM compatible personal computer, is located at the technician's console. Communication between these devices is implemented over a fiber optic RS-232 data link. This configuration allows experiments to be performed remotely by using a series of keyboard typed commands, by programming the host to send a series of commands, or by directly programming the remote system. As an example of its capabilities, the controller was used to tune and match arrays of receiver coils for localized imaging and to record the rectal temperature of a sedated rat during image acquisition. 相似文献

许多电子产品都带有串口,启用它们之前或复位以后都需要通过自身所带的串口进行一些初始化设置,通常都是使用笔记本电脑的串口,通过串口线连接进行初始化设置,由于接线麻烦,距离短,笔记本笨重,很不方便。随着手机和平板电脑等移动终端的普及和应用,为我们的工作带来了许多方便,也为实现无线调试这些设备成为可能。本文设计了一个基于安卓移动终端的串口调试系统,可以完成与各种具有串口的电子设备进行初始设置、调试等功能,极大提高了设备设置和调试的方便性。 相似文献

Manual configuration of IP routers is an expensive, time-consuming, and error-prone process. For large Internet service providers, establishing service for new customers is a major part of the financial cost of running the network. Increasingly, these customers want to exchange routing information with their provider(s) using the border gateway protocol (BGP), a complex and highly programmable interdomain routing protocol. This article describes how a provider can configure its connections to BGP-speaking customers, from the technical questions asked of new customers to the individual configuration commands applied to the production routers. We present a case study of a technical questionnaire and describe how the provider assigns unique identifiers such as IP address blocks, interface names, and access control list numbers on behalf of the customer. Next, we describe an example set of provisioning rules that use the customer-specific information to generate a sequence of configuration commands - a "configlet" - for adding the new connection to the network; our configuration rules are expressed using Cisco Internet Operating System (IOS) commands as an example. Then we describe a database schema for storing and accessing the customer-specific data, and discuss how to use a virtual view on this database to populate a template that captures the syntax of the router commands. Our provisioning system provides an inexpensive, efficient, and accurate way for a provider to configure connections to new BGP-speaking customers. 相似文献
