    RAD Data CommunicationsJune 2011
  • Ethernet and IP VPNs: When to Use Which?
    Layer 2 (L2) Ethernet and Layer 3 (L3) IP/MPLS VPNs offer different benefits for different needs:
  • L2, L3 Key Decision Factors:Cost, Scalability, Control
    Low price per Mbps: Ethernet VPNs are ideal for high throughput typically required at large branches or data centers
    IP/MPLS VPNs:
    Fit highly distributed installations, a very large number of sites
    Low to medium bandwidth rates
    Ideal for remote access
    Control:
    Enterprises comfortable with self managing their IP address space and routing tables prefer Layer 2 Ethernet VPNs
    Businesses without in-house knowledge of IP switching fundamentals, prefer turnkey VPNs
  • L2 & L3 Service Combination
    Example (Retail industry):
    • Ethernet VPN for data center, distribution centers and headquarters:
    • Meet bandwidth, delay and control requirements for high volume content delivery, storage and disaster recovery
    • L3 VPN for branch connectivity:
    • Ideal for any-to-any VoIP connectivity and point of sale data processing
  • In Conclusion
    L2 and L3 services are complementary for different customer needs
    Key decision factors are cost, scalability and level of control desired by the enterprise
    A growing trend of integrating Ethernet and IP/MPLS VPN features for the same customer
