全局加速器，网络负载平衡器(NLB)和Gateway Load Load Balancer(GWLB)之间的闲置超时会有所不同。
**全局加速器：AWS Global Accelerator中TCP连接的默认空闲超时为90秒[9]。 AWS Global Accelerator通过终止AWS网络边缘的TCP连接来减少设置时间[6]。
**网络负载平衡器(NLB)：NLB具有可配置的TCP空闲超时，可以将其设置为60至6000秒之间的任何值[7] [10]。 TCP连接的默认超时为350秒[7]。
**网关负载平衡器(GWLB)：GWLB还具有可配置的TCP空闲超时，其范围与NLB相同(60至6000秒)[8]。以前，GWLB的固定TCP空闲计时器为350秒[8]。配置TCP空闲超时的能力使用户可以将防火墙和应用程序的超时值与GWLB保持一致，从而确保连续的交通流量并减少干扰[8]。
