In modern network setups, the three-tier architecture has emerged as a powerful and scalable model, consisting of the access, aggregation, and core layers. This hierarchical design enhances network performance, flexibility, and security. In this article, we will explore the details of the three-tier architecture and its application in network setups.
Features of Three-Tier Architecture
The three-tier architecture is important for organizing network parts. It improves performance and ensures smooth data flow in a network. Then we will provide a detailed introduction to the Three-Tier Architecture.
Access Layer
The access layer, often referred to as Layer 2 (L2), is responsible for connecting end devices to the network. Compared with the aggregation and core layer, access layer switches have low cost and high port density characteristics.
Aggregation Layer
The aggregation layer serves as the convergence point for multiple access switches, forwarding and routing traffic to the core layer. Its primary role is to manage the data flow from the access layer and provide a link to the core layer. This layer may include both Layer 2 and Layer 3 (L3) switches, and it must be capable of handling the combined traffic from all access layer devices.
Core Layer
The core layer is responsible for high-speed data routing and forwarding, acting as the backbone of the network. Engineers built this system for high availability and low latency. It mainly uses L3 switches to ensure fast and reliable data transmission across the network.
Applications with FS Solutions
FS switches offer practical solutions for this architecture by categorizing their devices according to function and layer. For instance, switches with names starting with a number of 3 or lower typically represent L2 or L2+ switches, suitable for the access layer. Meanwhile, switches with names starting with 5 or higher denote L3 devices, ideal for aggregation and core layers.
In the previous section, we discussed the characteristics of three-layer architecture. Based on these features, we can say that L2/L2+ switches work well for connecting end devices. They are good for managing simple networks in small LANs.
On the other hand, L3 switches help with communication between different subnets. They also meet the complex needs of larger networks.
For L2+ enterprise-level switches, the S3410-48TS-P has a built-in Broadcom chip and supports virtual stacking of up to 4 units. With a 740W Power Budget, it can power more devices and even support high-density access to different devices.
The popular L3 switch, the S5810-48TS-P, features a ‘P’ in its name, indicating its power capability to simplify network infrastructure and cabling. Additionally, it has three built-in fans (2+1 redundancy) with left-to-right airflow, ensuring high availability and reliability. Its layered design makes it an excellent choice for aggregation in large campus networks and as the core of small to medium-sized enterprise networks.
With FS switch solution, you can receive personalized solutions and designs tailored to your unique needs. Additionally, FS has a warehouse in Singapore, resulting in faster delivery times and onsite testing to ensure quality. We are always committed to providing high-performance switching products through professional and reliable expertise.
Conclusion
In conclusion, the three-layer architecture, as a traditional deployment model, has its unique advantages and is well-suited for campus network deployments. Based on this architecture, we can select switches from different layers to meet specific needs.
