A 100G upgrade is an architecture and migration programme, not simply an optics purchase.
Planning areas
- Traffic and growth modelling
- Platform and forwarding-scale selection
- Optics, cabling and compatibility
- BGP, IGP and high-availability design
- Monitoring, telemetry and capacity evidence
- Staged customer or service migration
- Rollback and acceptance testing
When is 100G justified?
The decision should be based on sustained traffic, burst behaviour, resilience headroom, port economics, growth and the operational cost of remaining on the current platform.
