2. 4 Reasons to buy Nortel Networks LANs Provides Business continuity with no single point of failure at the hardware level and faster recovery from network failures (<1 Sec)

3. Business Continuity-Nortel LANs reduce network downtime High availability with sub second recovery from failures using S- MLT Brokerage House Cost of downtime=$6.5M/hr*=1805$/sec Average number of times service unavailable** over 3 years=10 Cost of Downtime over 3 years= Nortel Solution <1 sec Recover=1,805x10=$18,050 Competitive Solutions 8-40Sec Recovery= $14,000-72,000x10=$140,000-720,000 *numbers based in Fiber Channel association survey **Network outage or service degradation Credit Card Sales – Cost of downtime=$2.6M/hr*=722$/sec –Average number of times service unavailable** over 3 years=10 –Cost of Downtime over 3 years= Nortel Solution <1 sec Recover=722x10=$7220 Competitive Solutions 8-40Sec Recovery= $5777-28,880x10=$57,770-288,800 Nortel Networks LAN solution decreases the Revenue Lost due to network downtime by an order of magnitude when compared to a LAN solution from competition

4. Analysts Opinion on the Nortel LAN Infrastructure Passport 8600 (June 2002) “Threatening to products servicing the enterprise backbone and data centre markets.” “The Passport 8600's delivers necessary intelligence to support complex security requirements and QoS applications, as well as highly advanced Web and content switching applications” The Tolly Group testing of PP 8600 (May 2002) Achieves sub-second failover of multi-linked trunks, maintaining state of voice over IP and video sessions Delivers high availability with respect to hardware failures or upgrades Node or link failure: Recovery time 0.91 secs Ethernet interface failure: Recovery time 0.38 secs

5. Improved network level redundancy Traditional solution: Spanning Tree Layer-3 Switch Disadvantage: - Blocked ports – not all links used - Slow failover if active link fails. -No redundant connection of servers - Quickly becomes complex to configure and manage Edge Switch (layer2) Advantage: -Standards based solution -Supported by all vendors Layer-3 Switch
