AWS Network Load Balancer (NLB) now supports QUIC protocol in passthrough mode, enabling low-latency forwarding of QUIC traffic while preserving session stickiness through QUIC Connection ID. This enhancement helps customers maintain consistent connections for mobile applications, even when client IP addresses change during network roaming.
With QUIC support, customers can reduce application latency by up to 30% through fewer packet round trips and ensure seamless user experiences across varying network conditions. This is especially useful for mobile applications that require users to move between cellular towers or switch from WiFi to cellular networks, without losing connection state. You can enable QUIC support on your existing or new Network Load Balancers through the AWS Management Console, CLI, or APIs. Once enabled, NLB forwards QUIC traffic to targets by using the QUIC Connection ID to maintain session stickiness even when a client roams.
QUIC support is available at no additional charge in all AWS commercial and AWS GovCloud (US) regions. QUIC traffic is metered within existing UDP Load Balancer Capacity Unit (LCU) entitlements.
