ایجاد محدودیت دانلود بر اساس نوع فایل در میکروتیک

/ 10 سپتامبر 16

با نحوه مدیریت پهنای باند در شبکه داخلی با استفاده از ابزار Queue Tree در میکروتیک آشنا می‌شویم.

با استفاده از این ابزار می‌توان پهنای باند خاصی را بین یگ گروه از کاربران به اشتراک گذاشت و برای ترافیک نرم‌افزار‌های خاص و یا حتی سایت‌ها و فایل فرمت‌های خاصی اولویت بالاتری برای استفاده از پهنای باند مذکور در نظر گرفت.

در این سناریو اولویت را بر اساس فرمت فایل دانلودی در نظر می‌گیریم. مثلاً از کل پهنای باند اولویت دانلود برای فایل‌های iso باشد.

در ابتدا فایل فرمت‌ها را از طریق layer7-protocol  به روتر معرفی می‌کنیم.

/ip firewall layer7-protocol add name=”EXE” regexp=”\\.(exe)”
/ip firewall layer7-protocol add name=”RAR” regexp=”\\.(rar)”
/ip firewall layer7-protocol add name=”ZIP” regexp=”\\.(zip)”
/ip firewall layer7-protocol add name=”7z” regexp=”\\.(7z)”
/ip firewall layer7-protocol add name=”CAB” regexp=”\\.(cab)”
/ip firewall layer7-protocol add name=”ASF” regexp=”\\.(asf)”
/ip firewall layer7-protocol add name=”MOV” regexp=”\\.(mov)”
/ip firewall layer7-protocol add name=”WMV” regexp=”\\.(wmv)”
/ip firewall layer7-protocol add name=”MPG” regexp=”\\.(mpg)”
/ip firewall layer7-protocol add name=”MPEG” regexp=”\\.(mpeg)”
/ip firewall layer7-protocol add name=”MKV” regexp=”\\.(mkv)”
/ip firewall layer7-protocol add name=”AVI” regexp=”\\.(avi)”
/ip firewall layer7-protocol add name=”FLV” regexp=”\\.(flv)”
/ip firewall layer7-protocol add name=”WAV” regexp=”\\.(wav)”
/ip firewall layer7-protocol add name=”RM” regexp=”\\.(rm)”
/ip firewall layer7-protocol add name=”MP3″ regexp=”\\.(mp3)”
/ip firewall layer7-protocol add name=”MP4″ regexp=”\\.(mp4)”
/ip firewall layer7-protocol add name=”RAM” regexp=”\\.(ram)”
/ip firewall layer7-protocol add name=”RMVB” regexp=”\\.(rmvb)”
/ip firewall layer7-protocol add name=”DAT” regexp=”\\.(dat)”
/ip firewall layer7-protocol add name=”DAA” regexp=”\\.(daa)”
/ip firewall layer7-protocol add name=”ISO” regexp=”\\.(iso)”
/ip firewall layer7-protocol add name=”NRG” regexp=”\\.(nrg)”
/ip firewall layer7-protocol add name=”BIN” regexp=”\\.(bin)”
/ip firewall layer7-protocol add name=”VCD” regexp=\\.(vcd)

سپس با استفاده از ابزار Mangle نسبت به علامت‌گذاری پکت‌های هر فایل فرمت به شکل زیر اقدام می‌کنیم:

بعد از این کار هم می‌توان از قسمت Firewall Filter دانلود برخی از فایل‌‌ها را ممنوع کرد و هم از طریق قسمت Queue tree اولویت تخصیص پهنای باند برای هر یک از این فرمتٓ‌ها را تغییرداد:
