Use Cases of Huawei backbone switches in various banks

For details about how to use the Huawei backbone switch in various banks, see the following. In the network upgrade and Transformation Project of the Bank of China Zhejiang Jiaxing branch, Huawei provided a solution for the business and management status of Jiaxing branch through comprehensive and meticulous on-site analysis.

The transformed network system not only satisfies the network bandwidth requirements of the current business system of Jiaxing branch, but also reserves scalable space for future business development, at the same time, the reliability and security aspects have also been greatly improved. Even if any device in the network fails, it will not affect the normal operation of the network.

The original network cannot meet the requirements

The original LAN of The Bank of China building in Jiaxing, Zhejiang Province has been in operation for several years. It mainly uses three Cisco2948 Huawei backbone switches and connects a large number of HUB devices. The HUB serves as a shared device, because VLAN Division and other functions are not supported, broadcast packets sent by a host are received by all hosts on the network;

When there are many broadcast packets, the network performance is seriously affected, and the network access speed and security composed of HUB are seriously reduced. In addition, the HUB switching capacity and processing performance are very limited. As the volume of data carried by the LAN rapidly increases and the number of business types increases, the original network system of Jiaxing branch cannot meet the requirements.

Jiaxing Bank of China is a secondary branch. However, due to the economic development in Zhejiang, the business volume and data volume of Jiaxing branch are relatively large, especially the recently running application systems and the number of users on the network have increased significantly, therefore, they have higher requirements on networks. First, they have higher and higher requirements on network bandwidth;

The second is the requirement on network reliability. In addition, it also puts forward higher requirements on network security. Based on Network requirements and cost-effectiveness, Jiaxing Bank chose the network product of Huawei switch to comprehensively transform the network system of Jiaxing bank.

From core to access

Through specific research on Jiaxing branch, Huawei has developed a network transformation solution for different strategies at the core layer and access layer. After the transformation, the new business network can greatly improve the network port density and transmission bandwidth to meet the evolving requirements of applications.

Two Quidway S8016 Huawei backbone switches are used in the network center of Jiaxing branch to achieve access to all floor collection points in a fully redundant structure, at the same time, the office network server system and network management system are connected by devices such as Quidway S6506 and Quidway S3026 through the Gigabit Service Board provided by Quidway S8016.

The Quidway S8016 group in the network center is the switch center of the entire network and also the routing center of the entire LAN, its effectiveness is ensured by Quidway S8016 full-line multi-layer processing performance and high-bandwidth 2 × Gigabit Ethernet of the backbone network.

Each floor access collection point is implemented through the Quidway S3026 Huawei backbone switch. A layer-2 access structure is designed. The layer-3 and layer-4 processes are completely handled by the core Quidway S8016 group, this makes the network layers clear, simple, and efficient. Quidway S3026 is a layer-2 switch product that supports 1-gigabit backbone networks for access by Huawei's working group. All the ports support wire speed forwarding, switching capacity of 12.8Gps, and packet forwarding rate of 6.55 Mbps, this effectively guarantees the business traffic of Jiaxing branch.

Implementation Effect

Huawei has met various standards in terms of the overall functions of the solution, such as speed restrictions, comprehensive redundancy, comprehensive access capabilities, implementation of various functions with standard technology, unified network management and security, etc.

Network Performance

In this solution, the Quidway S8016 core is selected as the core device of the LAN. The Huawei backbone switch has 16 Network Module slots and has sufficient scalability, it represents a new generation of large-scale enterprise LAN/WAN backbone solutions and provides upgrading, high performance, and application control features to fully meet the growing demands of Jiaxing branch in the informatization process.

Quidway S8016 also provides a complete set of application services, including transparent web Cache and redirection, traffic priority division and Traffic Shaping, multi-layer security, application load balancing, and application content testing. These services ensure the effective implementation of complex applications such as e-commerce, enterprise resource planning, IP voice transmission, and customer relationship management at all levels from the desktop terminal to the WAN during business operation of Jiaxing branch.

Its modular design not only makes it cost-effective, but also protects users' investment for future upgrades. The hardware-based two-to three-tier wire rate forwarding technology provides a complete layer-2 to seven switching feature, Qos Assurance System, and security management mechanism, this fully satisfies the demands of Jiaxing branch for multiple businesses, high reliability and large capacity.

Scalability

With the continuous development of banking services, the demand for network resources often changes with the application. Therefore, the system constructed in this solution should be flexible, flexible System Configuration and resource redistribution to meet different existing or future needs.

The Huawei Quidway S8016 and S3026 Huawei backbone switches used in the solution fully support the industry's main exchange, routing, and network management standards. It is easy to configure and can be managed remotely through the Quidview management solution or other methods. In addition, the Quidway S8016 switch is based on the multi-layer switching network architecture to facilitate system expansion and smooth technical upgrade. Currently, the Quidway S8016 switch adopted by Jiaxing branch is basically only configured with 5 ~ Six business slots.

There are about 10 spare slots left for future expansion to ensure the continuity of investment. In the future expansion, you only need to purchase modules and directly insert them into the existing Quidway S8016 switch for use, you do not need to re-purchase the switch or restart the Huawei backbone switch S8016 to Support Board Hot swapping ).

As an important part of the Business System of Jiaxing branch, the reliability of the network system is an important requirement to ensure work efficiency. This solution fully considers this requirement in the selection and configuration of network equipment. In order to fully ensure the high reliability of the core exchange platform, each Quidway S8016 is configured with a dual-route switching unit, a dual-switch engine, and multiple power supplies, including a distributed switching structure that prevents any single point of failure.

In the solution design, two GE Gigabit Multimode Optical ports are used for redundant connections between S3026 and S8016 of the Huawei backbone switch. The device starts the STP protocol to ensure the normal operation of the Ring Network, when any node or line in the backbone network fails, the physical ring structure will exert its full redundancy and self-healing advantages.

The network formed after the transformation of Jiaxing bank LAN is a comprehensive network that can meet both existing needs and future network business development needs, in Jiaxing, the local area network of the Bank of China will certainly carry more business types, such as video, IP Phone, wireless LAN access, etc, the smooth development of these services requires local area network equipment to provide corresponding QoS Assurance capabilities. Huawei's Quidway S8016 switch has the QoS capability, fine granularity of traffic control, and sufficient number of flow queues, it can better meet the Business Guarantee capability.
