方案概述通过流量标记和队列管理实现以下优先级：最高优先级：PING、DNS次优先级：小包流量（上行<192B/下行<512B）、网页流量最低优先级：其他常规流量一、流量标记配置（Mangle）1.1 整体配置视图1.2 配置脚本/ip firewall mangle # ICMP标记 add action=mark-packet chain=forward comment="Mark Ping" new-packet-mark=PING passthrough=no protocol=icmp # DNS标记 add action=mark-packet chain=forward comment="Mark DNS Query" new-packet-mark=DNS_P passthrough=no port=53 protocol=udp # SpeedTest标记 add action=mark-packet chain=forward comment="Mark SpeedTest" new-pack
