What reliability advantage does Frame Relay offer over leased lines?
- Frame Relay access circuits are higher-grade circuits than leased lines.
- The pathways for virtual circuits inside the carrier are meshed.
- From end to end, a single virtual circuit uses a fixed error-checked path.
- Frame Relay uses more-sophisticated error-detection methods.
Explanation: A Frame Relay cloud typically is a meshed network of circuits and Layer 2 switches (usually ATM). This allows for redundancy within the provider’s network that does not exist with a dedicated leased line.
