  2. Wholesale Ethernet To use or offer Ethernet Wholesale… • Efficient, controlled, standards-based hand-off • Optimized, assured QoS: Strict SLAs • Uniform service delivery to off-net locations Wholesale Customer Your Network Wholesale Provider Your Customers Wholesale Hand-offs IGMP Router SLAs

  3. Wholesale Ethernet MEF 9+14 Carrier Ethernet Connectivity Dropped Packets LAN Link Classify Provider • Establish CIR, EIR, burst profile, CoS • VLAN tag to create / unwrap EVCs Provider S-VID Push Priority Marked EVC EVC S-VID Pop

  4. Wholesale Ethernet Establish & Maintain H-QoS Dropped Packets Per-Flow LAN Link Provider Priority Marked H-QoS Points H-QoS General Traffic: Advanced Priority Queues LAN Provider Highest Priority: Real-Time Queue (no delay)

  5. Wholesale Ethernet • Required standards • 802.1ag (CFM) • Y.1731 (CFM & PM) Fault Detection Fault Verification / Loopback Customer / Link Layer Provider CFM OAM Operator 3 Operator 1 Operator 2 Fault Isolation / Linktrace Fault Notification PM • Expected Performance • GbE: 100 sessions • 10 GbE: 1,000 sessions • Sub-ms precision: 1-way Frame Delay & Variation (1-way & round-trip) Frame Loss

  6. SLA Monitoring • SLAs are the language of wholesale • Monitoring is the currency that backs it up • Real-time reporting & accountability expected • ► Especially for new providers ►Especially because it’s Ethernet • Ethernet OAM is not enough • Often limited, software-based: • ►precision, density, frequency • Interop & partial feature issues • No IP visibility, blocked by routing • Often per-port, not per-VLAN • May not reach off-net locations

  7. Ethernet Wholesale: • E-NNIU / NIDs offer integrated layer 2 & 3 SLA monitoring • Hardware-based units deliver required performance Wholesale Customer E-NNIU Wholesale Provider NID Your Network IGMP Router SLA EMS • Provides low-cost, uniform off-net circuit termination • Centralized data collection enables portal-based reporting
