CDN 筛选

#!/bin/bash
##版本：V2.1.2
#新功能，支持ip地址全自动下载，更新优选完毕后推送至TG，再也不怕脚本没有成功运行了。
#使用脚本需要安装jq和timeout，新增openwrt专用cf_RE.sh文件，运行cf_RE.sh即可在openwrt安装jq和timeout两个扩展。
#其他linux请自行安装jq和timeout。
#主程序为ip_down.sh。

#测速地址
CFST_URL=https://download.parallels.com/desktop/v15/15.1.5-47309/ParallelsDesktop-15.1.5-47309.dmg
#测速线程数量；越多测速越快，性能弱的设备 (如路由器) 请勿太高；(默认 200 最多 1000 )
CFST_N=200
# 指定测速端口；延迟测速/下载测速时使用的端口；(默认 443 端口)
CFST_TP=8443
#下载测速数量；延迟测速并排序后，从最低延迟起下载测速的数量；(默认 10 个)
CFST_DN=10
#平均延迟上限；只输出低于指定平均延迟的 IP，可与其他上限/下限搭配；(默认9999 ms 这里推荐配置250 ms)
CFST_TL=250
#平均延迟下限；只输出高于指定平均延迟的 IP，可与其他上限/下限搭配、过滤假墙 IP；(默认 0 ms 这里推荐配置40)
CFST_TLL=40
#下载速度下限；只输出高于指定下载速度的 IP，凑够指定数量 [-dn] 才会停止测速；(默认 0.00 MB/s 这里推荐5.00MB/s)
CFST_SL=3
#更新几个 默认10个
CFST_P=10
