Failure | Description | Cause |
Connection | The connection communication fails or many packets are discarded. | The connection is damaged. For example, the cable is cut off. |
Port/fiber optic component | The port/fiber optic component fails to be read or has an transfer exception due to hardware or software failures. | Hardware failure: incompatible version, contaminated or damaged port. Software failure: incorrect port status, port in UP status without receiving or sending packets, frequent port on/off, or cyclic redundancy check (CRC) error. |
Network device | The exchange or router on the IDC side is unavailable. | Hardware failure: power supply, port, component or cable failures. Software failure: exchange/router error or incorrectly configured. |
Data center at the access point | The data center encounters network disconnection, or the access point is unavailable. | The data center cannot function normally due to earthquakes, fires or other disasters. |
Architecture | Use Case | Business Elasticity | Availability | Cost |
Suitable for use cases that require excellent business availability and elasticity, including the key production and real-time data transaction. | Highest | Highest | Highest | |
Suitable for key business that requires high availability and elasticity. | Medium | Higher | Medium | |
Suitable for non-critical business, including the cloud development and testing environments. | Medium | Medium | Medium | |
Suitable for non-critical business that does not require high elasticity and availability. | Low | Low | Low |
Failure | Business Impact |
Connection | The connections loads increase, and the business continues. |
Port/fiber optic component | The connections loads increase, and the business continues. |
Network device | The connections loads increase, and the business continues. |
Data center at the access point | The connections loads increase, and the business continues. |
Failure | Business Impact | Recovery Measures |
Connection | If each connection is used 50% or less, the connection loads burst and the business continues. If each connection is used greater than 50%, the connection will be full-loaded, some data will be lost, and the business continues. | If the business data is lost, you need to apply for a new connection and spend 2-3 months to restore the business. |
Network device | If each connection is used 50% or less, the connection loads burst and the business continues. If each connection is used greater than 50%, the connection will be full-loaded, some data will be lost, and the business continues. | If business data is lost, you need to check and repair the network devices. The recovery time depends on the specific failure. |
