Summary & Conclusions
Why Ethernet Services?
Most Cost-effective Support of Today’s 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)
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

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)
Putting it Into Practice:
How to Migrate to Ethernet
□ Step 3: Don’t 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:
•
•
•
•
