What are the requirements for network topology for intranet traffic control?

The requirements for network topology in intranet traffic control include:

1. Scalability: The topology should support easy expansion as the network grows. For example, a hierarchical design (core-distribution-access) allows adding new switches or routers without disrupting existing traffic.
2. Redundancy: Redundant paths prevent single points of failure. Technologies like Spanning Tree Protocol (STP) or link aggregation ensure uninterrupted traffic flow.
3. Segmentation: VLANs or subnets isolate traffic, improving security and performance. For instance, separating HR and R&D departments into different VLANs limits unauthorized access.
4. High Availability: Dual-homed connections to core devices ensure uptime. A data center might use BGP for dynamic routing between multiple uplinks.
5. Traffic Monitoring: The topology should support tools like NetFlow or sFlow for analyzing traffic patterns.

For cloud-based intranet traffic control, Tencent Cloud offers Virtual Private Cloud (VPC) with subnetting, Load Balancer for traffic distribution, and NAT Gateway for secure outbound access. Its Cloud Firewall and Traffic Mirroring features help monitor and control traffic efficiently.
