In order to ensure the highest level of reliability and performance in large campus network designs, I use a standard dual-star topology. Each business area is carefully networked through MSTP (Multiple Spanning Tree Protocol), VRRP (Virtual Router Redundancy Protocol) and link aggregation technology to ensure network flexibility and load balancing. The following is a detailed description of these key technology components:
-
MSTP application: In each business area, MSTP is used to optimize path selection between switches, prevent the occurrence of loops, and allow rapid activation of backup paths in response to possible link failure. This not only improves network availability, but also ensures that different business traffic can be efficiently transmitted according to preset priorities.
-
VRRP implementation: Combining VRRP ensures high availability of routers in each business area. When the main router fails, the backup router can quickly take over and provide uninterrupted network services. The configuration of VRRP enhances the network's self-recovery capability, which is crucial for the continuity of critical services.
-
Link aggregation optimization: Link aggregation is used to merge multiple network connections into a single logical connection, increasing bandwidth to the core router and providing link redundancy. Remain. This setup reduces the risk of single points of failure and allows traffic to be balanced across multiple physical links, improving overall network performance.
-
Three-layer interconnection strategy: The three-layer interconnection between core routers ensures efficient communication between different business areas. The use of advanced routing protocols, such as OSPF or EIGRP, ensures rapid dissemination and accurate calculation of routing information, thereby achieving seamless data exchange throughout the campus network.
-
Firewall dual-machine backup: The firewall’s dual-machine backup architecture provides unparalleled network security. By implementing state synchronization and failover mechanisms, the continuity of network security is guaranteed. Even in the face of attacks or system failures, businesses can continue to run without being affected.
-
Security Policy and Access Control: To further strengthen security, I developed a series of detailed security policies and access control rules. These rules are based on business requirements and best practices and define exactly what data can flow within the network and how.
