Cara Menggunakan Alat Ini

Pilih jumlah ISP provider (2 sampai 5) dan tentukan mode operasi: PCC Load Balancing + Failover atau Active-Backup Failover murni.
Tentukan antarmuka LAN bridge, nama interface tiap ISP, IP gateway lokal modem, bandwidth download/upload aktual, serta host target pemeriksaan ping (misalnya 1.1.1.1 atau 8.8.8.8).
Periksa rasio pembagian beban otomatis dan jumlah stream PCC yang dihasilkan, lalu salin script RouterOS v7 yang telah dilengkapi bypass RFC1918 ke terminal router.

Contoh Perhitungan Nyata: Dual-WAN 100M + 50M (Rasio 2:1)

Contoh terhitung: Kombinasi 2 ISP (ISP1 100M dan ISP2 50M) menghasilkan rasio proporsional 2 : 1 dengan total 3 stream PCC pada antarmuka bridge-lan (150 Mbps agregat).

Konsep Dasar & Catatan Teknis

Per Connection Classifier (PCC) adalah mekanisme penyeimbang beban (load balancing) pada MikroTik RouterOS yang membagi paket data ke beberapa koneksi internet berdasarkan kombinasi hashing alamat IP asal, alamat IP tujuan, serta nomor port. Tidak seperti teknik per-packet round-robin yang dapat merusak sesi login perbankan dan situs HTTPS karena paket dari koneksi yang sama melompat antar IP publik yang berbeda, PCC menjamin bahwa seluruh paket di dalam satu koneksi TCP/UDP yang sama akan selalu dilewatkan melalui ISP yang konsisten selama sesi berlangsung. Kalkulator ini menghitung rasio bobot pembagian koneksi secara proporsional berdasarkan kapasitas bandwidth masing-masing ISP menggunakan algoritma pembagi bersama terbesar (FPB / GCD). Sebagai contoh, jika ISP 1 memiliki kecepatan 100 Mbps dan ISP 2 memiliki kecepatan 50 Mbps, rasio beban yang terbentuk adalah 2:1 dengan total 3 stream PCC. Beban internet klien akan didistribusikan ke ISP 1 sebanyak 66,7% dan ke ISP 2 sebanyak 33,3%. Jumlah stream dibatasi secara cerdas agar tabel firewall mangle tetap ringan dan tidak membebani penggunaan CPU router. Selain pembagian beban, kalkulator ini menerapkan arsitektur Recursive Routing Failover modern di RouterOS v7. Metode ini tidak hanya memeriksa apakah link fisik atau modem ONT menyala, melainkan melakukan ping berkala ke IP publik eksternal (seperti 1.1.1.1 atau 8.8.8.8) melalui gateway masing-masing ISP dengan parameter scope dan target-scope. Apabila terjadi kabel fiber optik putus di jaringan inti ISP, router akan mendeteksi hilangnya akses internet dalam hitungan detik dan secara preemptive mengalihkan seluruh trafik ke ISP cadangan tanpa perlu intervensi manual.

Cara Perhitungan (Rumus & Langkah)

Rumus Matematika

Bobot Awal ISP = max(1, round(Bandwidth ÷ 10))
FPB (GCD) = gcd(Bobot ISP1, Bobot ISP2, ..., Bobot ISPN)
Rasio Sederhana = Bobot Awal ÷ FPB
Total Stream PCC = Σ(Rasio Sederhana) (diskala jika > 15 untuk efisiensi CPU)
Recursive Route: Gateway host check via modem gateway dengan scope=10 dan target-scope=11

Langkah Substitusi

Configured 2 WAN links with total aggregated capacity of 150 Mbps
Calculated bandwidth weights via GCD reduction: ISP1 (100 Mbps) : ISP2 (50 Mbps) → Ratio 2 : 1 (3 PCC streams total)
Generated RouterOS v7 routing tables, RFC 1918 bypass mangle rules, and recursive host monitoring for ISP1 via 1.1.1.1, ISP2 via 8.8.8.8

Pertanyaan yang Sering Diajukan (FAQ)

Mengapa classifier 'both-addresses-and-ports' menjadi rekomendasi utama?

Classifier ini mengacak koneksi berdasarkan IP pengirim, IP tujuan, serta port. Ini menghasilkan persebaran trafik paling merata untuk banyak pengguna browsing dan download tanpa merusak koneksi HTTPS karena sesi port tunggal tetap berada di satu ISP.

Apa fungsi bypass RFC 1918 pada script mangle PCC?

Rule accept untuk alamat lokal (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) diletakkan di urutan paling atas agar trafik antar-VLAN dan akses ke modem ONT tidak terkena mark routing PCC ke arah internet publik.

Bagaimana cara kerja Recursive Routing Failover pada RouterOS v7?

Router menetapkan rute statis ke IP publik tertentu (misalnya 1.1.1.1) dengan scope=10 melalui gateway modem. Rute default (0.0.0.0/0) kemudian diarahkan ke 1.1.1.1 dengan check-gateway=ping dan target-scope=11. Jika ping ke 1.1.1.1 gagal, rute default otomatis nonaktif.

Apakah PCC bisa menggabungkan kecepatan download dari satu koneksi tunggal (single-stream)?

Tidak. Satu sesi koneksi tunggal (seperti download file di browser biasa) hanya melewati satu ISP. Kecepatan gabungan 100+50 = 150 Mbps baru dirasakan saat terdapat multi-koneksi (seperti torrent, download manager multi-thread, atau banyak pengguna bersamaan).

Kalkulator Bandwidth MikroTik (Simple Queue, Burst, PCQ, FQ-CoDel)

Hitung Limit-At (CIR), Max-Limit (MIR), Burst, PCQ, dan FQ-CoDel RouterOS v7 lengkap dengan generator script konfigurasi otomatis.

Generator Port Forwarding (DST-NAT) dan Hairpin NAT MikroTik

Buka port server/NVR ke internet publik (DST-NAT) dan cegah koneksi loopback timeout dari dalam jaringan kantor menggunakan Hairpin NAT.

Kalkulator Subnet IPv4 dan CIDR

Hitung alamat network, broadcast, rentang host usable, netmask, wildcard, biner mask, dan tipe alamat IPv4 (RFC 1918, RFC 3021 /31, CGNAT).
