10. TDMSwitch Voice Data Video Quality of Service • SDH famous for QoS • Guaranteed Bandwidth • Fixed latency • By reserving transmission time (timeslots)

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

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

13. SDH ring Gigabit Ethernet Rings (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
