Carrier Ethernet Is Continuously Evolving
• CE 2.0 was the first step.
• Industry developments:
• New services.
• SDN and NFV.
• Orchestration.
• Further simplifications are on the way.
• Ex. Zero Touch Deployment, Segment Routing

What You Need To Know About Carrier Ethernet
• General definition;
• Terminology;
• Service types;
• Service attributes;

MEF Defines Carrier Ethernet As A Service
Carrier Ethernet is a service
that is ubiquitous, standard and
carrier class, differentiated from
classic Ethernet technology by
5 key attributes:
Metro Ethernet Forum: industry body that standardized Carrier
Ethernet Services.
Standardized
Scalable
Resilient
Manageable
Quality of Service

CE Services Definitions Are Technology Agnostic
• Based on abstractions.
• Technology examples:
• L0/L1 Transport;
• L2 Switching;
• IP/MPLS;
• Various Access types.
• Service requirements should define technology.
• Technology must fulfill the 5 carrier class attributes.

Why Deploy Multi-CoS for Carrier Ethernet?
• Allows improved network utilization;
• Allows improved network monetization;
• Provides better application performance;
• Enables service differentiation;
• Some customers demand it.

Why Deploy Standardized Multi-CoS Model?
• Industry expertise;
• Simple yet flexible model;
• Common terminology;
• Consistency;
• Reference values for Service-Level-Specifications (SLS).

Classes of Services And Performance Tiers
• Performance Tiers (PT) and Service Level Specifications (SLS):
• Performance Tiers provide pre-defined SLS metrics and values.
• There are 4 Performance Tiers*:
• PT1: Metro (250 km / 155 mi)
• PT2: Regional (1,200 km / 745 mi)
• PT3: Continental (7,000 km / 4,350 mi)
• PT4: Global (27,500 km / 17,090 mi)
• May be applied to an EVC or OVC.
*Note: Distances are provide as reference.

Cisco Innovations

Implementing CE 2.0 Features
• Multi-CoS:
• 2R3C Policer/Shaper;
• Ingress/Egress traffic management;
• Performance Tiers for SLS.
• Advanced envelope and ranking – very new, under investigation.
• E-NNI:
• Standard 802.1ad interface;
• Originally up to 10Gbps, added 100G later;
• Active/Stand-by LACP;
• 802.3ah Link OAM.

Implementing CE 2.0 Features
• Service OAM:
• 802.1ag/Y.1731;
• PM and FM;
• Not all MEG Layers are required (keep it simple)
• EPL Option 2:
• Relatively new, requires some attention with L2CP tunneling.
• For certification, EPL Option 1 is also accepted.
