Multi-WAN Vigor Router là giải pháp sử dụng nhiều đường truyền internet để chia sẻ dung lượng tải, hoặc để gia tăng khả năng chịu lỗi kết nối mạng cho hệ thống. Bài viết này sẽ giải thích cơ chế cân bằng tải ( Load Balancing ) và chuyển đổi dự phòng ( Failover ) trên Router Draytek.

Automatic Load Balancing :

Mặc định, tất cả các cổng Wan đang active sẽ tham gia tiến trình Load Balance khi nó được kết nối vào Router. VD : khi bạn có 1 đường truyền VNPT có tốc độ 20MB, và 1 đường truyền Viettel có tốc độ 30MB, khi đó tổng tốc độ băng thông khi thực hiện Load Balancer là 50MB.

Lúc này cổng WAN phụ sẽ được kích hoạt để đảm bảo tính liên tục của đường truyển Internet, và khi cổng WAN chính có thể hoạt động lại được, thì cổng WAN phụ sẽ tự động được tắt một lần nữa.
