Carrier Ethernet Terminology • UNI (User-to-Network Interface) – Physical interface/demarcation between service provider and subscriber – Service start/end point • Ethernet Virtual Connection (EVC) – An association of two or more UNIs • Three types of EVC – Point-to-Point – Multipoint-to-Multipoint – Rooted Multipoint (Point-to-Multipoint) • EVCs and Services In a Carrier Ethernet network, data is transported across Point-to-Point, Point-to. Multipoint and Multipoint-to-Multipoint EVCs according to the attributes and definitions of the E-Line and E-LAN services • NNI (Network-to-Network Interface) – Demarcation/peering point • Between service providers (NNI) • Between service provider internal networks (I-NNI) (For full presentation of Ethernet Services visit www.

Bandwidth Profiles & Traffic Management Bandwidth Profiles per EVC (service) and per Co. S – CIR (Committed Information Rate) • CIR assured via Bandwidth Reservation and Traffic Engineering – EIR (Excess Information Rate) • EIR bandwidth is considered ‘excess’ • Traffic dropped at congestion points in the network – CBS/EBS (Committed/Excess Burst Size) • Higher burst size results in improved performance EVC-2 EIR EVC-1 CI CIR EIR R EI R CIR EVC-3 Co. S 6 10 Mbps UNI (port) UNI EVC 1 EVC 2 1 Mbps CIR for Vo. IP Co. S 2 6 Mbps CIR for VPN data traffic 3 Mbps for Internet Access BWPs can divide bandwidth per EVC (service) over a single UNI – Multiple services over same port (UNI) – Co. S markings enable the network to determine the network Qo. S to provide CIR defines the assured bandwidth EIR improves the network’s Goodput 11

Carrier Ethernet Interconnect Challenge Operators need to interconnect their Carrier Ethernet Networks • Current implementations UNI B 2 – Limited in features, proprietary and/or ad-hoc – Differing feature and functionality transparency – Do not support MEF Carrier Ethernet services – Require extensive discussions between operators in order to verify each operator’s Carrier Ethernet product and operational capabilities Operator B UNI A 1 UNI A 2 UNI B 1 Operator A UNI D 1 UNI A 3 UNI C 2 Operator C UNI C 1 UNI B 3 Operator D UNI D 3 UNI C 3 UNI D 2 Proprietary interconnect Every Interconnect arrangement is unique 12
