مفهوم Load Balancing بدین شکل است که از ۲ یا چند سرویس دهنده مختلف برای انجام یک کار واحد بطور همزمان و متوازن استفاده کرد . سرویس دهنده ها میتوانند DNS ، Internet ، Database و یا Computing باشند که ما در این مقاله نحوه ی انجام این کار را در Internet Load Balancing توضیح میدهیم . در این اموزش می خواهیم اموزش لود بالانس میکروتیک را به صورت pcc به شما یاد دهیم درصورت هرگونه سوال می توانید سوال خود را درقسمت نظر ها مطرح کنید تا سریعا پاسخ دهیم
در این سناریو ما دوتا اینترنت یکی کنیم درصورت قطعی اینترنت اینترنت دیگر جای ان را بگیرد
دراین قسمت هم می توانید فیلم اموزشی Load Balance pcc mikrotik مشاهده بفرمایید
