Why was ATM regarded the Holy Grail ?

• Scalable Bandwidth Economical Deployment

– 25, 155, 622 Mbps etc

• Ubiquitous LAN/MAN/WAN– “ATM Everywhere”

• Quality of Service Good for Voice/Video– Bandwidth /Latency

• Resilience Rock solid infrastructure

– Meshed networks

Bandwidth by the Slice

• Committed Information Rate (CIR) -type services for Ethernet

• Bi-direct rate shaping– Control traffic on Egress– Police traffic on Ingress

SDH Restoration

• Key attribute of Sonet/SDH– SDH – Multiplexed Switching Protection (MSP)– Sonet - Automatic Protection Switching (APS)– 50-60ms failover

(Gigabit) Ethernet Restoration

• Ring or Mesh topology• Link state routing algorithms

– Convergence times• OSPF ~ 6 seconds• IS-IS ~ 6 seconds• (Fast) Spanning Tree ~1 sec

• MPLS improves recovery– Reserve paths before failure– 10-50 ms

• New Ring technologies– Resilient Packet Ring– EAPS < 1 sec failover
