Established in 1958, Huishan Second People’s Hospital is located in Huishan New Town. The new hospital has a total construction area of 40,000 square meters, 320 inpatient beds and 213 parking spaces with a total investment of about 200 million RMB. The hospital has 326 existing medical staff. There are 23 clinical departments including Emergency Department, Department of Critical Care Medicine, Cardiology, Respiratory Medicine, Neurology, etc.
With the construction of the new campus, it is necessary to establish powerful medical information management systems (such as HIS, PACS, etc.). But due to the limitations of wired networks, the system is restricted to play a greater role. For this reason, the new zone of the hospital was decided to build a wireless network, completely breaking this limitation.
üReliability and security
Since medical services information is carried by wireless network, and this kind of information is closely related to the vital signs of the patients, errors are not allowed to occur on the wireless. the wireless also requires the reliability and security provided by the wired network.
üPerformance and QoS
Wireless networks require high performance and strong quality of service, PACSand video surveillance must be able to run quickly and smoothly
üThe wired network
We chose 2 layers of network structure for the customer.
At core layer, we chose 2 units of DCRS-7608E, high performance chassis switch, as core switches. It provides 10G connection to aggregation devices. VSF, virtual switching framework, was running on them to provide core device redundancy.
At access layer, we chose PoE switch S5750E-28X-P-S which connects up to the core swtich DCRS-7608E by 10G fiber, down to AP by 1G twisted pair. PoE powering was chosen because it can reduce the cost of power wiring, reduce the construction complexity.
üThe wireless network
Wireless controller used 2 unit of DCWS-6028 to provide AC 1+1 backup and unified management for all the APs. 802.11ac high performance indoor access point – WL8200-I2 was chosen to coverage the Corridor area, it will provide high bandwidth WiFi access and suitable for high density scene. In-wall access point WL8200-W2 was chosen to coverage the hospital wards rooms and office.
For network management, the DCLM is used to monitor status of all the equipments including switches, AC and APs.

DCN Solution Highlights
üAC 1+1 backup.
DCN AC redundancy mechanism ensures continuity of wireless user business. The flow of information won’t be interrupted at all In case of a single point of failure.
üFast link fault detection mechanism
Combined with the WLAN dual-link connection mechanism, when the active AC fails, the backup AC can detect and implement active-standby link switching in milliseconds.
üWIDS (Wireless Intrusion Detection System) and WIPS (Wireless Intrusion Prevention System)
DCN wireless system implements early detection of malicious user attacks and intrusion of wireless networks. And then according to test results, intruder AP, clients and other intruders will be taken into control to ensure wireless network security.
Most sources of attack are unknown, so DCN adopts “combining static and dynamic” as an all-around technical feature that defends the network environment. IDS Attack Detection Prevents this flood attack by constantly monitoring the amount of traffic per device.
übuilt-in control strategy
Control strategy based on 5 elements group include rich and comprehensive policy rules based on MAC, IP, port, protocol, and flow.
High performance and Enhanced QoS
When the network is congested, according to the different service level agreement of the business, control and forward traffic flow differently to solve the congested problem.
Both wireless data transmission and wireless terminal access are performed in the air. The control and management of wireless access is much more difficult than that of wired access. As an expert of wireless technologies, DCN has developed the DCWS-OS software platform, and raised eight AirControl features, so as to exercise optimal control, scheduling, and management of wireless data and terminal access in the air, thereby bringing the same experience as with a wired network to users.
