S12700 Agile Switches Heal Hospital Networks

21-05-2014 17:15:00

Background

The Third Affiliated Hospital of Guangzhou University of Chinese Medicine (GZUCM) integrates medical treatment, teaching, and research for both western medicine and traditional Chinese medicine. The hospital is an important research center for Chinese orthopedics science.

Challenges

To provide connectivity for a new building, the hospital wanted a network that could accommodate service growth with network scalability and logical isolation between internal and external networks. Reliability was key. Even when single-point failures occur, the network was expected to stably process internal services such as the Hospital Information System (HIS), Laboratory Information System (LIS), and Picture Archiving and Communication System (PACS). The hospital also wanted to support wireless services.

Solution

To prevent service interruptions caused by single-point failures, Huawei used 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 the hospital network’s Operations and Maintenance (O&M), Huawei used the unique Packet Conservation Algorithm for Internet (iPCA) technology of the company’s S12700 Series Agile Switches. This algorithm marks, colors, and counts packets of services — such as remote video feeds — to implement precise quality detection and real-time fault location without extra traffic costs. iPCA enables O&M personnel to easily obtain network status and ensures the quality of video streams for remote medical teaching and consultation.

Huawei protected the hospital network against unauthorized intrusions with a security solution based on the Big Data concept. Huawei’s S12700 Series Agile Switches implement this security firewall using a hardware card that helps O&M personnel find security risks by analyzing user behaviors. The firewall card enables the network to actively defend against attacks, resolving security problems with mobile payment and remote wireless access that cannot be solved by traditional security devices.

Mobile medical treatment is a key project of the Ministry of Health and a focus of medical IT at GZUCM. Wireless services support ward rounds, nursing, and infusions. Huawei used the native Access Control (AC) function of the Agile Switches to manage and control Access Points (APs) and forward AP traffic through Ethernet Network Processor (ENP) cards. These capabilities help the hospital quickly deploy wireless services and simplify wired and wireless network management.

S12700 Series Agile Switches provide unified management, policy, and forwarding for wired and wireless services. This combined management capability ensures uniform, optimized user experience on both wired and wireless networks.

Benefits

The Huawei solutions implemented at Third Affiliated Hospital of GZUCM enables the hospital network to support a wide variety of services. Huawei S12700 Series Agile Switches function as core devices on the network, with full programmability and rapid service provisioning, reducing the need to replace hardware. The live network can smoothly evolve to a Software-Defined Networking (SDN) architecture, providing a more open and reliable network, faster transmission speed, higher security, and easy scalability.
