Network Requirements of Shanghai Public Health Clinical Center
 

    Shanghai Public Health Clinical Center has a complete hospital information management system, clinical information system, office automation system, and medical imaging information management system. In order to provide better medical services for patients with the new crown, the hospital is also equipped with a remote video conferencing system and a wireless Internet access system. Hospitals need a stable, secure, and high-performance wired and wireless network to support large-scale database access, mobile applications, comprehensive applications of images, video, and audio. The wired and wireless integrated network provided by Extreme Networks for the Shanghai Public Health Clinical Center perfectly supports the complex applications of the hospital and helps the hospital fight against the new crown epidemic. At present, it participates in the construction of the aided network and operates more than 100 switches and 1,000 wireless APs.

• high reliability
   

    The Extreme network solution has high reliability and availability. The key equipment supports redundant backup and has a strong fault tolerance function. The AP can automatically adjust the signal strength according to the needs to ensure the normal operation of various applications in the area, especially mobile medical equipment. . Extreme's wireless network has better self-healing capabilities and site-keeping capabilities. Even if the core controller fails or the link is interrupted, it can ensure normal business development without loss of business functions. When individual AP services are interrupted, adjacent APs will automatically increase the coverage area to ensure that there are no coverage blind spots for wireless services.
 

• high security
   

    In terms of security defense, the Extreme wireless network realizes the marginalization of network security policies on the AP side. Even if a certain AP is attacked and paralyzed, it will not affect the entire network business. The powerful Airdefense system helps customers proactively protect and ensure wireless air interface security, internally prevents compliant terminals from accessing illegal network access points, and externally blocks illegal terminals from invading compliant network access points. Network resources and security logs are clear at a glance.
 

• Manageability
   

    The network system can realize unified centralized management, monitor the network online, locate and troubleshoot quickly, configure the network and allocate resources reasonably, improve the utilization rate and performance of the network, and provide a complete set of security precautions. It can effectively prevent the system from being accessed by unauthorized personnel.
 

• high scalability
   

    The existing network has already run more than 100 switches and 1000 wireless APs online. Due to the large scale of the network, the hospital is divided into multiple wards in the network design, and redundant aggregation switches and redundant wireless controllers are configured for each ward. Configure core switches and central wireless controllers in the network center. The Extreme wireless network system supports hierarchical management. The central wireless controller VX9000 can manage the wireless controller NX5500 in the ward, so as to perform unified configuration and management of wireless APs in the whole hospital. VX9000 can support the management of a maximum of 25,000 APs. The expansion of the hospital network provides guarantees.
