branch network, the Internet, supporting DDN,FR,ISDN,PSTN and satellite data network connections. 2. network management system: the system planning, supervision, design and control of the use of network resources and activities, is achieve optimal network performance, including the following aspects: performance management: the multifaceted network performance monitoring and management, to ensure that the performance of the Internet to maintain at a high level. Configuration management: monitoring and configuration of network information. Account management: measure the utilization of network resources. Fault management: detection, registration, prompt the user to network failures and, if possible, automatically repair network problems. Safety management: according to the staff of planning to control network access protection network will not be easily broken. Remote access management: including equipment management, user rights management, access management for remote users. Network security: network security from the physical layer, network layer, application layer, and many levels of consideration, and have the perfect virus protection. 3.3.4 system resources of management system in intelligent of factory construction many application of based Shang, to makes all application can smooth, efficient of run, while makes whole factory distribution of computer resources get concentrated, and full and monitoring, must for whole computer systems established a perfect of system monitoring platform, makes user can through this platform achieved on whole system of full management, these management including: security management network management event/state/exception management database management detection work flow management Storage management performance and output management services/help desk change and configuration management, inventory and asset management application management 3.3.5 the host system 1. host system performance, can meet the needs of various applications, high performance to price ratio. 2. the host system has a mechanism for storing backups, needs information stored in the system, as well as key home security needs. 3. critical hosts should take into account multiple aspects of cluster needs. 3.3.6 factory NET 1. goals: broadband multimedia, Office, production and research to provide the best environment and platform, built State of the art network connecting all Department offices, workshops and laboratories. 2. network functions: support for broadband multimedia services; provide advanced platform for production, Commerce, scientific research; provide a good environment for academic exchange, and high speed Internet CERNET,CHINANET, quick access to the INTERNET, Exchange information with counterparts at home and abroad, work in concert and exhibition company, factorybranch network, the Internet, supporting DDN,FR,ISDN,PSTN and satellite data network connections. 2. network management system: the system planning, supervision, design and control of the use of network resources and activities, is achieve optimal network performance, including the following aspects: performance management: the multifaceted network performance monitoring and management, to ensure that the performance of the Internet to maintain at a high level.
