Network Service
Delivery Controller

One Convergence Network Services Delivery (NSD) is a software based platform that enables orchestration, lifecycle management and service assurance of L3-L7 network services for various cloud and network platforms that includes OpenStack Neutron and Cisco ACI. NSD’s innovative policy driven approach for network service automation and orchestration not only enables rich differentiated services comprising of open source & vendor services but also offers choices for insertion models and service chains.

NSD significantly enhances what is available in OpenStack FWaaS, LBaaS and other *aaS with support for vendor specific features, licensing, high availability, service chaining and common way to orchestrate & configure a diverse set of network services. The solution includes built in analytics and visibility that provides great insight into deployed network services and applications it front-ends. Further NSD adapts network services to any changes in applications or network that they front-end.

Use Cases

Managed Service Provider

Managed Service Providers (MSPs) enabled to offer enterprise grade IaaS platform with the availability of the following functionality:

  • Complete automation of all layers of networking
  • Rich set of network services provided to the tenants
  • New revenue models by offering flexible and dynamicnetwork services

Enterprise IT

The solution offers the following functionality for Enterprise IT operators, providing cloud infrastructure for application owners in various business groups:

  • Flexibility and agility in deploying virtual network services
  • Simplicity of definition via intent policy for the application owners
  • Assurance of network services
  • Best of breed network services and availability of vendor specific features

Managed Network Services Cloud

Cloud operators can now compose rich network services and offer them as a cloud service. New business models to support "bring your own device" (BYOD) via dynamic insertion of customer provided network services over the base set provided by cloud operators.

Application Visibility As A Service

Operational visibility and analytics provided across all layers of networking can be offered as a service to tenants. This not only allows for customer specific visibility into networks and network services but also into the customer applications.


Network Service Delivery platform extensive feature set allows cloud operators tomanage & orchestrate L3- L7 network services in OpenStackclouds.Using NSD lifecycle management, service assuranceand visibility/ monitoring features operators can provide highly available rich differentiated network services offering to their customers.

Network Service Delivery (NSD) platform unique architecture applies the SDN principles of separation of control, management and data planes to the deployment of L3-L7 network services. The architecture is distributed at the control and data plane to support the hyper-scale cloud use cases of Enterprise private clouds, Managed Service provider clouds and Service provider clouds.

The platform implements a pluggable architecture to provide life cycle management and configuration of network services in a manner agnostic to the deployed network services. The platform allows multiple vendor network services to be chained and managed allowing operators to offer rich and flexible network services with no vendor lock-in. The platform supports the community driven intent policy model (GBP) that vastly simplifies networking and network services deployment and operations for operators and end users.

The platform will be made available as an open source project allowing community participation and innovation. Further the platform is architected to be extensible to support multiple network and cloud fabrics under a common API model thus simplifying the operator dilemma of vendor lock-in, hybrid environments and migration.
