AWS Direct Connect adds VIF Rate Limiters for dedicated connections

infraaws
feature

AWS Direct Connect now offers Virtual Interface (VIF) Rate Limiters on dedicated connections to prevent network congestion from traffic spikes. This feature allows setting maximum bandwidth allocations for up to 10 VIFs, dropping excess packets to protect other VIFs on the same connection. New CloudWatch metrics provide visibility into bandwidth usage and dropped packets, aiding in configuration adjustments. VIF Rate Limiters are available in all supported AWS Regions and configurable via the console, API, or SDK.

  • VIF Rate Limiters for dedicated Direct Connect connections

    AWS Direct Connect now supports Virtual Interface (VIF) Rate Limiters on dedicated connections, allowing users to set maximum bandwidth allocations for up to 10 VIFs to prevent congestion. This feature helps ensure that unexpected traffic spikes on one VIF do not impact workloads on other VIFs sharing the same connection by dropping excess packets.

Enhancements (1) ›
  • Enhanced visibility into VIF bandwidth utilization

    New Amazon CloudWatch metrics are published, including traffic utilization as a percentage of configured capacity and dropped packet counts for rate-limited VIFs. These metrics facilitate understanding bandwidth usage and setting alarms based on defined thresholds.

Notes (1) ›
  • Availability and configuration of VIF Rate Limiters

    VIF Rate Limiters are available in all AWS Regions supporting dedicated Direct Connect connections and can be configured through the AWS Direct Connect console, API, or SDK.
