The MEF Work Towards the Third Network

2

Today’s Two Modern Data Networks

On-Demand & Ubiquitous Performance & Security

Internet

Lack of Agility No Service Assurance

Imagine a new type of network service combining the best of both worlds and removing the limitations …

3

A New Type of Network Service

• Agile – Delivery of new, dynamic, on-demand services

• Assured – Delivery of performance and security guarantees

• Orchestrated – Delivery of automated service across service providers

4

The Third Network

Objective …

– Combine on-demand agility of the Internet with the performance & security assurances of Carrier Ethernet

– Deliver the service between physical Ethernet ports (UNIs) and Virtual service end-points

– Define abstractions to hide the complexity of underlying network technologies

… for services delivered end-to-end over multi-provider, multi-domain networks

LSO and Programmatic Control

To programmatically control a service, one needs to know:

1. What it is – Formal information model defining service constructs

2. What can I do – APIs to manipulate the service

• Decomposition – EVC segments

• Flow domains – Forwarding

Carrier Ethernet Information Model

Carrier Ethernet Management Information Model

Defined in MEF 7.2, updates in-progress in MEF 7.3

• Define the set of management information necessary for Carrier Ethernet services

• Provide the base model that will be applied to specific management interfaces – Network Management to Element Management Layer

(NML-EML)

– SDN Control of Network Infrastructure

Service Configuration and Activation

Ongoing Service and Operations Committee project

• Framework of service requests to – Configure and activate Carrier Ethernet services

• Define – Requirements, use cases, business processes,

information and data models

– Application Programming Interface definitions (APIs)

• In context of activation phases

13

Service Activation Sequence

• Use information model

• Define API

• Apply standard methodology – sequence diagram

• Show interaction between object and processes

Relationship with SDN and NFV

• Don’t reinvent the wheel

• Each forum brings domain expertise

• Who is doing what, how is it related
