MEF Active Role in First/Last Mile Evolution

• Is it the first or a last mile case?
• Depends who you ask
• The last battle before the Global Interconnect

First / Last Mile
Carrier Network
Carrier Ethernet defined

• Intelligence move to the access
• Speed rates pushed from the access to the core
• Cost drifted down for better CAPEX/OPEX

SLAs and Performance Measurements

• Metro Ethernet Forum (MEF)
• Recommended key parameters for SLAs MEF 10.1
  (1.1)
• Service availability, frames lost, frame delay,
  inter-frame delay variation
• Defined the what, not the how
• Y.1731/802.1ag (MEF SOAM)
• Focused on end to end service OAM
• Includes both monitoring and test
• Frame delay, frame delay variation
• Frame loss ratio is still under debate for MP
  (Liaison with ITU-T SG12/Q17)
• Used for SLA verification
• RFC-2544
• Out of service testing service turn-up phase
• Throughput, frame loss, latency

• Service Assurance (frame loss, delay and jitter)
• Monitoring without service affecting
• Y.1731 synthetic frames injected with subscriber
  traffic at a rate where both the subscriber
  traffic and synthetic frames sum to a proscribed
  rate (CIR)
• 1-way measurements requires time synchronization
• Optional OpCodes (MCC, EXP, VSM)
