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 …

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

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

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

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
