ATM (Asynchronous Transfer Mode)
Offers very high speeds: 622 Mbps, 2.5 Gbps to 40 Gbps. Speeds are beyond most corporate needs today and high costs.
Connection-oriented (PVCs), unreliable
Quality of Service (QOS) guarantees critical traffic
- Minimize latency (delays)
- Inherent reliability (low loss rate)
Seen as the next generation before Ethernet surge
- But Frame Relay kept increasing in speed in low Mbps range where market demand was highest
