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

• Topology– Bus Star/Tree Mesh
• Packet Forwarding– Bus Repeater L2-switch L3-

• Quality of Service– CSMA/DC Full Duplex Priority
Controlled BW
• Distance– 2km 200m (CSMA/CD) Unlimited (Full

Quality of Service
• SDH famous for QoS– Guaranteed Bandwidth– Fixed latency
• By reserving transmission time (timeslots)

Bandwidth by the Slice
• Committed Information Rate (CIR) -type services for Ethernet
• Bi-direct rate shaping– Control traffic on Egress– Police traffic on Ingress
Min 5Mb/s VoIP
Min 15Mb/s Subnet X
Max 30Mb/s web data

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
