Definition:
ECMP (Equal-Cost Multi-Path) is a networking strategy that distributes traffic across multiple paths of equal cost to reach the same destination. In software testing, ECMP testing involves verifying that network traffic is properly load-balanced across multiple equal routes, ensuring optimal bandwidth utilization, fault tolerance, and proper failover behavior.
Key Features
- Load distribution: Traffic spread across multiple equal paths
- Fault tolerance: Automatic rerouting when paths fail
- Bandwidth utilization: Maximum use of available network capacity
- Dynamic balancing: Real-time adjustment based on network conditions
Example:
- Data Center Network Testing Network Setup:

[Load Balancer]

Path A Path B Path C (All equal cost)
