1.4.8 Transport Assessment Summary¶

Key Findings¶

MPLS: Reliable but expensive at $XX.XX/Mbps; phase-out candidate
Internet: Cost-effective at $X-X/Mbps; suitable for primary transport
5G: Available at major sites; viable for backup/burst capacity
Cloud Proximity: Direct internet provides 50-60% better SaaS latency

Transport Decision Matrix¶

Factor	MPLS	Internet	4G/5G	Recommendation
Cost	Poor	Excellent	Good	Internet primary
Latency	Excellent	Good	Fair	Internet + QoS
Reliability	Excellent	Good	Fair	Dual Internet
SLA	Excellent	Good	Fair	AAR failover
Scalability	Poor	Excellent	Good	Internet
