demand analysis
With the improvement of information technology and the continuous expansion of hospitals, the importance of the medical network is becoming more and more obvious. More and more medical staff are willing to use the network system for doctor rounds, patient care, equipment sharing and management, drug inventory and files And daily management such as medical records management.
The information points of a large hospital network are very dense, with a maximum of more than 1,000. The network coverage includes doctors 'offices, offices, registration departments, drug distribution departments, settlement departments, financial departments, nurses' duty rooms, and wards. And huge access units require a strong network core to ensure the efficient operation of the entire network. At the same time, due to the very strong correlation and continuity between medical departments, the failure of individual department outlets will lead to the stagnation or paralysis of the entire medical process, so the stability of the network is crucial. In addition, many data such as patient medical records, files, and medical data are stored in the medical network, and some of the content involves hospital secrets and patient privacy. In order to ensure that these important data are protected from illegal theft and malicious damage and tampering, network equipment is required to provide comprehensive And perfect security features. On the whole, a high-speed, stable, safe and uninterrupted network platform will be the ideal choice for major hospitals.
D-Link is based on the special needs of the medical industry, fully integrates its own product line, introduces advanced networking concepts, and specifically tailors a complete solution for large hospitals, designed to fully support the various applications and needs of the medical industry To help major hospitals achieve information management and management.
Network structure
Large hospital network solution
For the construction of the network system of large hospitals, D-Link applies an optimized two-layer network architecture, combining the convergence layer and the access layer of the network as the edge layer of the entire network system, which is directly powered by the core layer equipment. This flat structure design improves network operation efficiency and is easier to manage. It is very suitable for industry users with high requirements for network operation environment, such as hospitals. The network topology diagram is as follows:
The uninterrupted continuous operation of the system is the basic guarantee for the normal operation of the hospital, so it is very important to choose mature, advanced and stable network equipment, especially for the network core layer equipment. In this solution, D-Link selected 2 DES-6500 gigabit multi-layer switches as the backbone of the network. This switching device with carrier-quality provides a rich redundancy strategy, which can easily deal with any accidents in the network. Strongly guarantee the network's 24/7 operation. DES-6500 adopts the leading VRRP technology to achieve dual-machine redundancy and ensure the stable operation of the entire network system. At the same time, DES-6500 also provides a redundant power supply option, which avoids the occurrence of downtime due to the damage of a certain power supply, and adds another layer of protection for the continuous operation of large hospital network systems. In addition, DES-6500 also introduces a hot-swappable module design, which opens a convenient door for managers to replace faulty components at any time without interfering with the normal communication of the network. DES-6500 supports multiple routing protocols such as RIP, OSPF, IPX-RIP, Apple Talk Routing, etc., which ensures smooth communication between different networks, reduces network anomalies, and thus realizes smooth network operation. In addition, including links Multiple practical functions including aggregation protocol, spanning tree and rapid spanning tree make the entire network system as solid as a mountain.
In addition to stability, excellent performance is also an important reason why DES-6500 successfully serves as the core of the network. The DES-6500 provides 10 Gigabit uplink ports to achieve high-speed communication with external networks. The large backplane capacity of 352G enables all ports to have full line-speed switching capabilities, ensuring that the line speed can always be maintained under the huge network communication load. The exchange of Layer 2 and Layer 3 fundamentally eliminates the bottleneck of network congestion and ensures the high performance and high quality of the entire network system.
DES-6500 has 8 open slots, providing a variety of standardized interface types, users can flexibly choose the appropriate access method according to different network applications, and it is convenient for hospitals to deploy advanced medical equipment at any time.
DES-6500 provides rich QoS strategies and priority queues, providing sufficient network bandwidth and optimal network rate for the transmission of audio, video and other multimedia data files. The QoS function is of great significance to the hospital. It not only ensures the rapid forwarding of large-capacity data such as image data and photos between internal departments of the hospital, but also builds a smooth channel for telemedicine and online consultation.
Usually, a complete database is set up in the medical information system to record patient files, medical records, drug inventory and other important data in detail. If it is illegally stolen, tampered or destroyed, it will cause huge losses and extremely bad effects to the hospital Not only that, if the hospital network system cannot effectively block malicious attacks from the outside, it will seriously interfere with the normal work of the hospital, so the security of the medical network is self-evident, because DES-6500 is the first line of defense against the external network Therefore, the security performance of DES-6500 directly determines the prevention capability of the entire hospital network system. In view of this, DES-6500 provides multiple security strategies, including dynamic VLAN division based on 802.1Q standard, IP filtering function for controlling network traffic, multiple layers of quality of service support, advanced access control list ACL, and enhanced TACACS + RADIUS authentication, etc., and fully support the 802.1x standard, bring a full range of multi-level security protection for the hospital network to ensure foolproof.
In the plan, D-Link flexibly merges the aggregation layer and the access layer into one, and selects high-performance stackable switches DES-3526 to directly connect the inpatient building, outpatient building, office building, family area and other buildings into the network core to form A high-speed transmission path from the edge layer to the network center ensures rapid response between various departments of the hospital, shortens the time for patients to stay and wait in various departments, and thus speeds up the work efficiency of the hospital.
DES-3526 provides high-density port settings and industry-leading stacking capacity of up to 32 units. The superior scalability not only provides a sufficient number of ports at the edge of the network, but also further enhances the network flexibility. The hospital can be based on the actual information point The scale is flexible to determine the number of stacks and make the best use of it. It is very suitable for an expanding network environment like the hospital network.
Facing a large number of network access terminals, DES-3526 uses a single IP address management technology to achieve cluster management, provides a friendly Web-based interface to help administrators perform remote control and on-site debugging, and reflects the stacking unit ’s feedback through graphic and textual feedback reports Information to help network administrators easily troubleshoot network problems. This graphical, batch-based centralized management mode not only saves IP addresses, but also helps administrators centrally control and uniformly upgrade stacking groups, simplifying network deployment and management processes.
In addition, DES-3526 is based on multi-layer quality of service QoS to ensure that VoIP voice calls, video conferences, and network teaching in hospitals can be carried out smoothly. More enhanced features such as bandwidth control, multicast, port aggregation, etc. ensure that medical staff can easily deploy various Kinds of web applications.
