An E-Line is a service type defined by the MEF for connecting exactly 2 UNIs where those 2 UNIs can communicate only with one another. E-Lines are defined in MEF 6.2 and MEF 10.3.
EPL (Ethernet Private Line) and EVPL (Ethernet Virtual Private Line) are both services under the E-Line service type.
Service Type | Port-Based (All to One Bundling) | VLAN-Based (EVC identified by VLAN ID) |
E-Line (Point-to-Point EVC) | Ethernet Private Line (EPL) | Ethernet Virtual Private Line (EVPL) |
E-LAN (Multipoint-to-Multipoint EVC) | Ethernet Private LAN (EP-LAN) | Ethernet Virtual Private LAN (EVP-LAN) |
E-Tree (Rooted-Multipoint EVC) | Ethernet Private Tree (EP-Tree) | Ethernet Virtual Private Tree (EVP-Tree) |
E-Lines are used to create, among other solutions:
Private lines
Ethernet Internet access
Replacement for TDM private lines
E-Lines are the most popular Carrier Ethernet service due to their simplicity.
