Network Redundancy Architecture in Brazil — 99.99% Uptime Design
Multi-carrier redundancy design for enterprise and carrier networks in Brazil. Dual-homed BGP, geographically diverse fiber paths, and automatic failover under 30 seconds.
Redundancy Architecture Patterns for Brazil
Achieving 99.99% uptime in Brazil requires more than a backup circuit — it requires architectural diversity at the carrier, physical path, and routing protocol layers. JCM Carrier designs redundancy solutions that account for Brazil's specific infrastructure risks: concentrated fiber routes in São Paulo's Paulista corridor, single-carrier dependencies in secondary cities, and BGP convergence delays during failover.
Dual-Homed BGP
Active-active BGP sessions with two upstream providers. Traffic engineering via MED and local preference ensures optimal path selection with automatic failover.
Geographically Diverse Fiber
Primary and backup circuits routed through physically separate conduits and data centers, eliminating shared-risk infrastructure.
Multi-Carrier Last Mile
Last-mile diversity using fiber from one carrier and wireless (FWA/microwave) from another, ensuring no single-point-of-failure at the access layer.
Automatic Failover
BFD (Bidirectional Forwarding Detection) enables sub-second failure detection, triggering BGP failover in under 30 seconds.
