• Why Ethernet Services?
• Most Cost-effective Support of Todays
  Applications

• Business Demands Exceeding Capabilities of
  Legacy Infrastructures
• Triple Play Convergence (VoIP, Video and Data)
• Virtualization and Consolidation
• Collaboration Requires Any-to-any Connectivity
• Storage Area Networks and Backup and Recovery
• Carriers Planning End of Life of Frame/ATM
  Networks
• Desire to Leverage IP Efficiencies, Reduce Costs
• Ethernet Compares Favorably to Layer 3
  Alternatives
• Ethernet offers all of the capabilities and
  performance benefits of
• Layer 3, but at a lower Total Cost of
  Ownership (TCO)

4

• Why Ethernet Services?
• Ethernet is a Better Alternative than IP VPNs

• IP VPNs
• Low Cost, Ubiquitous Coverage, Best Effort,
  Point-to-point and hub and spoke
• Layer 3 MPLS VPNs
• Fully Meshed Connectivity with CoS/QoS Costly
  transition, Complex Operation
• Layer 2 Ethernet VPN
• Simple Fully Meshed Connectivity with CoS/QoS
  and VPLS High Performance, Low TCO

Point-to-Point
Hub and Spoke
Fully Meshed
5

• Deployment Impacts
• Ethernet Services Are Easier to Manage with
  Lower TCO

6

• Application Impacts
• Low Latency, Low Jitter Ethernet Ideal for
  Convergence

7

• Strategic ImpactsEmpowers Customers, Improves
  Competitive Advantage

8

• Putting it Into Practice How to Migrate to
  Ethernet

• ? Step 1 Evaluate Ethernet and decide to migrate
  away from legacy WAN
• ? Step 2 Get rid of old-school WAN equipment
• ? Layer 2 Communications will add a fully managed
  Ethernet switch (CPE)

9

• Putting it Into Practice How to Migrate to
  Ethernet

• ? Step 3 Dont worry about the installation with
  a Managed VPLS network
• ? Step 4 Plug your LAN switch or router directly
  WAN

Summary Conclusions

• Consider Ethernet VPLS services if
• Want to maintain control of their own IP routing
• Want to simplify WAN management
• Want to reduce CapEx and OpEx
• Need to scale bandwidth and support any-to-any
  connectivity
• Tips
• Demand strong service level agreements
• Look for global coverage
• Require
• VPLS
• Class of Service (CoS)
• Bandwidth-on-demand
• End-to-end management
