Commercial Network Services Lifecycle Management Using Model Driven Software Automation
As Software Defined Networking (SDN) and Network Functions Virtualization (NFV) become the modern approach to quickly deliver and offer network services, such as SD-WAN and valued added service with service chains; declarative & model driven orchestration technologies like TOSCA become the fabric to develop software automation tools & platform to manage the lifecycle of these network service applications and build an ecosystem for multiple vendors to participate & integrate with their VNF solutions.

Comcast architecture leverages a number of information models and orchestration tools including TOSCA and YANG to enable complete life cycle management of SDN and NFV functionalities and to configure the physical and virtual devices that comprise an end-to-end service.

During this webinar, the speakers will share how TOSCA is being used to describe the orchestration between the resources across a complex end to end service(s) such as SD-WAN and Cloud Security. Also how Comcast makes use of the TOSCA orchestration capabilities such as substitution/service decomposition for vendor abstraction to realize some of the VNF use cases. TOSCA’s interface and life cycle operations are used for the implementation aspects. TOSCA’s requirement, capability types, node referencing features helps to define and visualize the end-to-end service as a topology graph of inter-connected nodes and navigate across connected services.

YANG is a data modeling language used to describe the device configuration. Orchestration specific properties are modeled natively in TOSCA and device/network configuration properties are modeled as YANG. The syntax and semantic constraints and capabilities offered by YANG are made use of during service validation and activation.
