Path analysis

Path analysis evaluates connectivity between user's source and destination instances, offering visualization, fault diagnosis/location, and network architecture optimization tools.

Description:

• Path analysis checks user configurations for any restrictions without simulating packet transmission.
• Path analysis currently supports these source/destination instance types: Baidu Cloud Compute (BCC), Baidu Baremetal Compute (BBC), and subnets. Support for other product instance types will be added over time.

Application scenarios:

• BCC or BBC instance access within the same or across regions: The source and destination resources in this scenario can belong to different Baidu AI Cloud accounts.
• BCC or BBC instances and subnets can communicate with each other.

Quota:

• Path analysis policies: 100 (submit ticket to adjust quota)
• Historical records: 1,000 entries, non-adjustable;
• Concurrency analysis limit: 3 entries, non-adjustable

Create Path Analysis

Sign in to Cloud Management console and select Product Services - Network - Network Diagnostic Service (NDS) - Path Analysis.

Analysis results

Path analysis results may include: "-", which appears after creating an analysis policy, "accessible," and "inaccessible."

1. If the analysis result is "accessible," it means both the request and response directions are open.

2. If the analysis result is "inaccessible," it means the request direction is blocked, and no response direction path will be shown.

Note: Path analysis is currently unavailable as the path contains unsupported intermediate nodes.
