Interactive Network Calculators &Carrier Architecture Reference Engines
Rigorous, uncompromised technical utilities engineered for network architects, CTOs, and NOC engineers. Model transmission physics, kernel buffer tuning, overlay encapsulation taxes, and carrier BGP policies.
Bandwidth, BDP & MTU Sizing Engine
Model enterprise leased line bandwidth by headcount, calculate Bandwidth-Delay Product (BDP) single-stream TCP limits under RFC 1323, and size EVPN-VXLAN / IPsec MSS clamping values.
- Headcount & 1080p video concurrency modeling
- Single-stream TCP throughput ceiling & Mathis loss formula
- EVPN-VXLAN, IPsec ESP, and QinQ MTU overhead tax
- Dynamic Linux sysctl, Windows netsh, and Cisco MSS clamp syntax
Optical Link Budget & Attenuation Engine
Calculate end-to-end insertion loss across single-mode fiber (ITU-T G.652). Size power budgets for 10G, 100G, and 400G ZR+ optics, prevent photodiode burnout, and verify link headroom.
- 1310nm O-band (0.35 dB/km) vs 1550nm C-band (0.22 dB/km) math
- Fusion splice, bulkhead connector & AAWG DWDM mux loss accounting
- Receiver saturation burnout & attenuator pad warnings
- Live Cisco, FortiOS, and MikroTik optical DOM / DDM diagnostic commands
BGP Anycast & Prefix Sizing Visualizer
Simulate BGP path selection, verify RFC 7454 /24 and /48 Default-Free Zone (DFZ) route filtering limits, engineer inbound AS-Path prepending, and deploy RFC 7999 RTBH DDoS blackholing.
- RFC 7454 DFZ /24 IPv4 & /48 IPv6 boundary enforcement checks
- Dual-homed BGP path election simulator (Local-Pref vs AS-Path)
- RFC 7999 RTBH 65535:666 DDoS blackholing trigger simulation
- Route-map and prefix-list CLI generator for Cisco, FortiGate, and MikroTik
Why ManagedByUs Publishes Open Engineering Tools
Commercial telecom brokers conceal network physics behind opaque bandwidth tables and generic sales quotas. We believe enterprise infrastructure should be transparent and mathematically verifiable.
Whether you are an in-house network architect troubleshooting TCP window scaling over a transatlantic leased line, verifying ITU-T G.652 insertion loss before signing a 5-year dark fibre lease, or preparing BGP route-maps for multi-carrier failover, these tools provide the exact formulas and device syntax our own NOC engineers use in production.
