Public preview: Enabling Rate Limiting on ExpressRoute Direct Circuits

Published date: November 15, 2023

With ExpressRoute Direct, you can enable rate-limiting for your circuit to match the traffic volume with the configured bandwidth rate. This allows you to manage the traffic flow between your on-premises network and Azure over the ExpressRoute circuit. Rate-limiting helps you avoid network congestion, optimize port bandwidth usage and costs, and ensure consistent service quality.

Without this feature, or with rate-limiting disabled, the traffic over a circuit can exceed the configured bandwidth and reach the port bandwidth limit. This can affect the performance and reliability of your network.

You can enable rate-limiting for each circuit individually, giving you the flexibility to prioritize some circuits over others within your direct port. You can enable this feature during or after the creation of the ExpressRoute Direct circuit.
