   variation from the Controller MEP to the Responder MEP.

Measurement Bin   A Measurement Bin is a counter that stores the number of
    performance measurements falling within a specified range, during
    a Measurement Interval 
Measurement Interval   A period of time during which measurements are taken.
   Measurements initiated during one Measurement Interval are kept
   separate from measurements taken during other Measurement Intervals.
   It is important to note that this is different from T.

PM Function  A MEP capability specified for performance monitoring purposes
   (e.g., Single-Ended Delay, Single-Ended Synthetic Loss) 
PM Session  A PM Session is the application of a given PM Function between a given
  pair of MEPs and using a given CoS Frame Set over some (possibly
  indefinite) period of time. 
PM Solution A PM Solution is a set of related requirements that when implemented
   allow a given set of performance metrics to be measured using a
   given set of PM functions. 
PM Tool     A generic term used to discuss the application of a PM Function.
Proactive   OAM actions that are carried on continuously to permit timely reporting
   of fault and/or performance status. 
Resiliency  Performance The number of High Loss Intervals and Consecutive High
   Loss Intervals in T 
Responder MEP   In a single-ended session, the Responder MEP receives SOAM PDUs,
   from the Controller MEP, and transmits a response to the
   Controller MEP. SOAM-PM 
RFC         Request for Comment
Service Frame   An Ethernet frame transmitted across the UNI toward the Service
   Provider or an Ethernet frame transmitted across the UNI toward
   the Subscriber 
Single-Ended   A type of process where a MEP sends a measurement request and the
   peer MEP replies with the requested information so the originating
   MEP can calculate the measurement.
Sink MEP    In a dual-ended session, the Sink MEP receives SOAM PDUs, from the
   Controller MEP and performs the performance calculations. 
SLM         Synthetic Loss Measurement 
SNMP        Simple Network Management Protocol
SNMP Agent  An SNMP entity containing one or more command responder and/or
   notification originator applications (along with their associated
   SNMP engine).  Typically implemented in an NE. 
SNMP Manager   An SNMP entity containing one or more command generator and/or
   notification receiver applications (along with their associated
   SNMP engine). Typically implemented in an EMS or NMS. 
SOAM        Service OAM 
SOAM PDU    Service OAM frame, or Protocol Data Unit. Specifically, those PDUs
   defined in [IEEE 802.1ag], [ITU-T Y.1731], or MEF specifications
Synthetic Traffic   SOAM traffic that emulates service traffic in order to measure
  the performance experience. Delay measurements must use synthetic
  traffic, because user traffic does not contain standardized
  timestamp fields. Other measurements, such as Frame Loss, may also
  use synthetic frames for certain advantages (e.g., ability to
  measure loss in multipoint services). 
T           Time Interval for SLS Metrics.  The time over which a Performance
   Metric is defined.  T is at least as large as the Measurement
   Interval, and generally consists of multiple Measurement
   Intervals. 
TC          Textual Conventions 
TLV         Type Length Value, a method of encoding Objects
Two-way     A measurement of the performance of frames that flow from the
   Controller MEP to Responder MEP and back again.
