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

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)
