Switches play multiple roles in the network architecture:
switches play multiple roles in the network architecture:
- Access layer: connect terminal devices and provide basic network access;
- Aggregation layer: aggregate access layer traffic and implement security policies;
- Core layer: High-speed exchange of data packets to ensure low-latency communication across the network.
For example, in a three-tier architecture, core switches need to have high backplane bandwidth and low latency to support large-scale data center traffic. Access layer switches need to support PoE power supply to meet the deployment requirements of wireless APs and IP phones.
