contains the Customer Edge VLAN ID.
A frame sent from the Service Provider network to the CE.
An association of two or more UNIs that limits the exchange of
frames to UNIs in the Ethernet Virtual Connection

A Service Frame that is used for Layer 2 control, e.g., Spanning
Tree Protocol.
The process by which a Layer 2 Control Protocol Service Frame is
passed through the Service Provider network switches without being
processed by those switches and delivered to the proper UNI(s).
A Service Frame that has a multicast destination MAC address.
An EVC with two or more UNIs.
Excess Burst Size
A measure of the amount of bytes sent in back-to-back Service
Frames at the UNI.
A measure of long term average bit rate for a set of Service Frames
at the UNI.
Excess Information Rate
An EVC with exactly 2 UNIs.
An Ethernet frame transmitted across the UNI toward the Service
Provider or an Ethernet frame transmitted across the UNI toward the
Subscriber.
A UNI attribute in which the UNI can be in more than one EVC
instance.
The organization providing Ethernet Service(s).

User Network Interface
