Evolving Your Network With Metro Ethernet and MPLS VPNs: How to Determine the Best Fit for Your Enterprise

MPLS VPNs are best known for their flexibility to handle many different protocols and operate across a wide range of commonly available connection speeds that are typically used in branch office connectivity, point-of-sale applications, and the like. Ethernet has also become a popular solution for higher speed WANs. It leverages the simplicity of Layer 2 switching ubiquitous on high-speed LANs)\ and is therefore best used where IP is the sole protocol and only if multi-Mbps or Gbps connection speeds are possible.
