SAT (Service Activation Test) w oparciu o Y.1564

- Y.1564 – podstawy

RAX711 (A)

(4)

Y.1731 – podstawy

• IEEE 802.1ag: Connectivity Fault Management (CFM) • IEEE 802.3ah: Ethernet Link OAM (EFM OAM)

• ITU-T Y.1731: OAM functions & mechanisms for Ethernet based networks • MEF E-LMI: Ethernet Local Management Interface

• IP SLA’s: Performance Management using CFM and Y.1731 mechanisms

(5)

Y.1731 – podstawy

• Link Level OAM

• Operates on point-to-point, not propagated beyond a single hop • Slow Protocol – (Max rate of 10 frames per second)

Functions:

• OAM discovery

• Link monitoring – Event notification when error thresholds exceeded • Remote Failure Indication

(6)

Y.1731 – podstawy

• Maintenance Association End Point (MEP)

• Support the detection of connectivity failures between any pair of MEPs in an MA • Associated per MA and identified by a MEPID (1-8191)

• Ethernet frames realizing functions:

ETH-CC (Ethernet Continuity Check - Fault detection) ETH-LB (Ethernet Loopback - Fault acknowledgement) ETH-LT (Ethernet Link Trace - Fault location)

(7)

Y.1731 – podstawy

• Performance Measurement:

ETH-DM (Frame Delay/Jitter Measurement) ETH-LM (Frame Loss Measurement)

• ETH-AIS (Alarm Indication Signal) • ETH-RDI (Remote Defect Indication) • ETH-LCK (Ethernet Locked Signal)

(8)

Y.1731 – podstawy

Maitenance

Domain (MD) &

Level

• CFM packet in a lower-level MD is discarded after entering a higher level MD. • CFM packets in a higher-level MD can traverse lower-level MDs

• MD may nest and touch, but never intersect • Up to eight MD levels: (0..7)

(9)

Y.1731 – podstawy

Maitenance

Association

(MA)

• Monitors connectivity of a particular service instance ina a MD • Defined by a set of Maintenance End Points (MEP)

(10)

Y.1731 – podstawy

Maitenance

End Point

(MEP)

• Defines the boundaries of a MD

• Support the detection of connectivity failures between any pain od MEPs in MA • Associated per MA and indetified by MEPID (1-8191)

(11)

Y.1731 – podstawy

Maitenance

Internediate

Point (MIP)

• Support discovery of paths among MEPs and location of faults along those paths • Can be associated per MD and VLAN/EVC (automatically created)
