Metode dan Skema Load Balanching Administrasi Infrastruktur jaringan Kelas 12 TKJ SMKN 1 Boalemo Teori Dasar Load balance pada mikrotik adalah teknik untuk mendistribusikan beban trafik pada dua atau lebih jalur koneksi secara seimbang, agar trafik dapat berjalan optimal, memaksimalkan throughput, memperkecil waktu tanggap dan menghindari overload pada salah satu jalur koneksi. Dalam penggunaan loadbalancing tidak seperti rumus matematika 512 + 256 = 768, akan tetapi 512 + 256 = 512 + 256 artinya Bandwidth ke2 jalur tidak akan digabung.
