A Highly standardized, simple, scalable, secure (multi)point to (multi)point connection technology dethroning TDM, Frame Relay and ATM based connectivity services in enterprise WANs.
If leased line is the bitcoin of the connectivity services, carrier ethernet is the ethereum of them and here is why
Easy Implementation
Very easy to implement, no need for complex devices, just an ethernet switch
Various Service Types
EPL, EVPL, EP-LAN, EVP-LAN, EP-Tree, EVP-Tree
Cost Effective
Ability to select the exact bandwidth required
SDN and NFV Ready
Supports next generation software defined network and network function virtualization
Scalable
You can scale your bandwidth however you prefer with no technician required on-site
Standardized
The service is standardized by MEF so irrespective of the overlay carrier, the service is the same
