Carrier Ethernet is a Service
• Carrier Ethernet is a standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet
• It brings the compelling business benefit of the Ethernet cost model to achieve significant savings
Carrier Ethernet
• Scalability
• Standardized Services
• Service Management
• Quality of Service
• Reliability

EtherAccess Feature-setEtherAccess – Enhanced L2 Ethernet capabilities over any access infrastructure • Connectivity Options
– EPL/EVPL services (MEF certified)– Flow based
• Traffic classification and mapping– CE VLAN ID, P-bit, DSCP, IP Precedence
• Enhanced QoS – Policing per service– Dual leaky bucket supporting CIR+CBS, EIR+EBS– Scheduling – Queues according to Strict priority or WFQ – Rate limit on the egress port - Conforms egress traffic to specific rate
• Enhanced service creation & assurance OA&M– IEEE 802.3-2005 (Link OAM)– IEEE 802.1ag/Y1731 End-to-End (CFM/PM)– Powerful L2/L3 loopback Allow multiple independent SLA monitoring instances– Integrated RFC-2544 Generator
• Resiliency: – Linear protection based on G.8031– Ethernet Ring protection based on G.8032

– Link Aggregation Control protocol used to sync LAG members and identify failures
• Dual homing – 1:1 connectivity to two different upstream devices for node redundancy
Switch criteria:– Loss Of Signal (LOS) indication– Manual commands

Fault PropagationBased on OAM Loss Of Connectivity
• Network failure propagation to user ports– User ports are turned off upon Loss-of Connectivity (LOC) or Remote
Defect Indication (RDI)• Customer equipment senses the failure and immediately reroutes to
alternative path– Shortens restoration time by triggering restoration much faster
than native routing protocols

Management Flow Configuration
There are several procedures for configuring management flow:• SVI (Switched Virtual Interface) – Defines a logical port used to
associate the router interface with the remote device (peer). • Flow Classifications – Define the types of traffic.• Flow – Defines the In/Out paths.• Router Interface – Makes the ETX accessible from different
access points. The router provides a logical path at L3.

Bridge
• Bridge Entity enables E-LAN services• Bridge ports may be bounded to physical port or to Logical port. Bridge port
which is flow based should be bounded to SVI and connected to Physical ports with flows.
• VLAN aware bridge, configure for each VLAN port membership list needed.• When a bridge port is bounded to a physical port or any of the logical ports
