What is an Aggregation Switch in a Network? Why do we need to use Aggregation Switch? After reading this article, you can understand that What an Aggregation Switch is, how it works and why we need to use it.
What is an Aggregation Switch in a Network?
Aggregation switches consolidate data traffic from multiple network access switches into a single high-bandwidth link to the core network. In the traditional three-layer network model, the main role is to converge the access layer switch data, and then forwarded to the core switch, for the core layer to reduce the burden.
Using the aggregation switch increases bandwidth, improves redundancy, and enhances the overall performance and reliability of the network. Typically used in data centers or enterprise networks.
What is the Principle of operation?
Aggregation switch is the convergence point of multiple access switches, which serves to unify the accessed data and transmitting out the data. It can handle all traffic from access layer devices and provide all traffic to the core layer, so the aggregation switch needs to have high performance.
Usually, After the aggregation switch receives data from the access switch. It will perform local routing, filtering, traffic balancing, and QoS management. Then, it will handle security mechanism, IP address translation, and multicast management. Finally, it will forward the the processing results to the core layer switch or perform local routing to ensure the normal operation of the core layer.
Why we need the aggregation switch?
Data Aggregation: The primary function of an aggregation switch is to gather traffic from multiple access switches, which are connected to end-user devices like computers, printers, and other networked equipment. Instead of directly connecting every access switch to the core network, aggregation switches consolidate multiple connections into a single connection to the core.
Reduce Network Congestion: Without aggregation switches, all data from access switches must be transmitted directly to the core layer, which can cause congestion and impact network performance. Aggregation switches aggregate data from all access switches and transmit it in a unified way, thus reducing network congestion and improving overall network performance.
Superior Performance: For large networks with complex structures, long transmission distances, and over 200 users (with growth expected), aggregation switches offer better performance and higher speeds than access switches. They are more efficient in handling data transmission.
Simplified Network Management: Aggregation switches simplify management by centralizing traffic from multiple access switches. This allows administrators to focus on fewer devices, making tasks like updates, troubleshooting, and monitoring easier and less complex.
