Third Affiliated Hospital of Guangzhou University of Chinese Medicine (GZUCM), a hospital adopting both traditional Chinese and western medicine, is a comprehensive hospital integrating medical treatment, teaching, and research. The hospital is an important research center for the Chinese orthopedics science, which is a national and provincial key discipline in GZUCM. The hospital decided to build a digital hospital network for its new building. Future service growth, network scalability, and logical isolation between internal and external networks should be considered in network construction. Core devices should be robust and stable. Even when single-point failures occur, the network must stably process internal services such as hospital information system (HIS), laboratory information system (LIS), and picture archiving and communication system (PACS) services. The internal network should also support wireless services, ensuring the construction of mobile medical treatment in the hospital.
According to Huawei's experience in building digital hospitals, hospital service systems such as HIS, LIS, and PACS require the network to process services efficiently, transmit image information in real time, and have high reliability.
To prevent service interruptions caused by single-point failures, Huawei uses the industry's most advanced switch fabric hardware clustering technology: Cluster Switch System Generation 2 (CSS2). CSS2 technology virtualizes two physical core switches into a logical switch through switch fabric units (SFUs). The innovative 1+N backup of main processing units (MPUs) further improves cluster reliability.
To simplify network operation and maintenance (O&M), Huawei uses the unique Packet Conservation Algorithm for Internet (iPCA) technology of S12700 series agile switches to mark, color, and count packets of services such as remote medical video teaching and teleconsultation. iPCA technology provides precise quality detection and real-time fault location without extra traffic costs. It helps O&M personnel easily obtain network status, improves fault location efficiency, and ensures the high quality of videos used in remote medical teaching and teleconsultation. IT technologies and communications networks facilitate medical IT construction, but also bring various security risks. Unauthorized users may steal confidential hospital information for personal gain, access hospital application systems, and tamper data in the systems. Terminals may not have patches installed in time, causing worm spreading on the entire network. Based on the Big Data concept, Huawei S12700 series agile switches use a next-generation security firewall card to help O&M personnel find security risks by analyzing user behaviors. The firewall card enables the network to actively defend against attacks, solving security problems in mobile payment and remote wireless access that cannot be solved by traditional security devices.
Mobile medical treatment, compared to a crown jewel, is a key project in the Ministry of Health. It is also a focus of the medical IT construction in Third Affiliated Hospital of GZUCM. The construction of mobile medical treatment accelerates the deployment and implementation of wireless medical services such as wireless ward round, mobile nursing, mobile infusion, and patient positioning. To help the hospital quickly deploy wireless services and simplify wired and wireless networks management, Huawei uses the native AC function of S12700 series agile switches to manage and control APs and forward APs' traffic through Ethernet Network Processor (ENP) cards. S12700 series agile switches provide industry-leading unified management, policy, and forwarding for wired and wireless services, ensuring uniform and optimal user experience and management experience on the wired and wireless networks.
The implementation of Huawei solutions in Third Affiliated Hospital of GZUCM enables the hospital network to support various services. Huawei S12700 series agile switches function as core devices on the network. S12700 series agile switches have the full programmability and shorten service provisioning from two years to six months, removing the need to replace hardware. The live network can be smoothly evolved to a software-defined networking (SDN) network, providing a more open and reliable architecture, faster transmission speed, and higher security and scalability.
