which type of Ethernet services as defined by the MEF?

VPWS/EoMPLS offers which type of Ethernet services as defined by the MEF?

A.
E-Tree

B.
E-LAN

C.
E-Line

D.
E-Interworking

Explanation:

• E-Line is based on a point-to-point Ethernet Virtual Connection. Two E-Line services are defined:
– Ethernet Private Line (EPL): A very simple and basic point-to-point service characterized by low
frame delay,frame delay variation, and frame loss ratio. No service multiplexing is allowed, and
other than a committedinformation rate (CIR) no class of service (CoS) (Bandwidth Profiling) is
allowed.
– Ethernet Virtual Private Line (EVPL): A point-to-point service wherein service multiplexing (more
than oneEthernet Virtual Connection) is allowed. The individual Ethernet Virtual Circuits can be

defined with a rich set ofBandwidth Profiles and Layer 2 Control Protocol Processing methods as
defined by the Metro Ethernet Forum.
