NFVHybrid Transport Network

• Multiple transport networks, ranging from BT’s MPLS and

optical networks, to customers’ networks, to public Internet.

As suited to each site type.

• Interconnects to BT services, Data centres, 3rd party

providers and networks.

• NFV infrastructure.

Service Management and Presentation

• BT Next Generation Agile OSS.

• Network services managed through model-driven OSS. At the

heart of this is TOSCA-based orchestration and YANG-based

activation.

• Clean abstraction of network services, to allow decoupling

from commercial presentation.

• Digital service presentation of services, allowing real-time

management of service.

Centralised SDWAzN

Control and Policy

Management

SDN Overlay Network

• SDN overlay to transport networks, providing single coherent

E2E policy management and configuration for customer’s

network.

• Allowing extension out to 3rd party data centres and service

providers.

• Allowing strengths of each transport network to be accessed,

but via single E2E policy view.
