AI Technical Summary
In existing technologies, the single-NIC solution for virtual machines results in the inability to physically isolate management traffic from business traffic, posing security risks and asymmetric routing vulnerabilities. The multi-NIC solution requires pre-configured scripts, has low efficiency in batch configuration, lacks session persistence mechanisms, and has limited scalability.
On the cloud management platform, a management plane logical domain and a business plane logical domain are built, multiple virtual network interface cards are dynamically mounted, and on-demand routing configuration and session persistence are achieved through a policy routing daemon. A destination IP-based routing forwarding mechanism is adopted to avoid source IP policy routing rule restrictions.
It achieves physical isolation between management and business planes, improves security and communication reliability, enhances operational efficiency, ensures business continuity and bandwidth utilization, and has high scalability.
