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.

Standardized Multiple Classes Of Service

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.

State-of-the-art MPLS technologies for Carrier Ethernet

• Segment Routing

• Simplification of MPLS Control Plane;

• Label distribution via IGP;

• Source-based routing;

• EVPN (PBB-EVPN, EVPN-VPWS)

• Simplified Provisioning and Operation;

• Optimal Forwarding;

• Fast Convergence;

• High Scalability: MAC, VLAN, PW;

• Auto-IP

• Automatic IP address assignment

• Simplifies deployment and node insertion

• L3 ring behaves like L2 (plug-and-play)

• Autonomic Networking

• Zero-touch node deployment

• Secure in-band communication channel

• Baseline for auto configuration download and advanced automation aplications

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.
