5G Network Slices Orchestration for Guaranteed Connectivity
In a project that Amartus has realized for a tier-1 service provider, our team of experts delivered service composition and orchestration, and 5G Network Slices orchestration for guaranteed connectivity.
What was the challenge?
There were four crucial aspects to this challenge:
1. Service composition and ochestration of the following elements:
- Ordering
- Inventory
2. Northbound exposure of services via well-defined APIs for:
- Product Catalog
- Ordering
- Entire Service/Slice Lifecycle
3. Demonstrating the orchestration of a hybrid end-to-end use case to showcase our work in action. The two cases were:
- SD-WAN over 5GIC and customer’s/other fixed underlay
- IoT services within or across 5GIC & Juniper testbed
4. Orchestration of 5G network slices for guaranteed connectivity
What is 5G Network Slicing?
5G network slicing is a network architecture that enables the multiplexing of virtualized and independent logical networks on the same physical network infrastructure. Each network slice is an isolated end-to-end network tailored to fulfill diverse requirements requested by a particular application.
What is 5GIC?
5GIC stands for 5G Innovation Centre, which is the UK’s largest academic 5G wireless communications infrastructure research center. 5GIC brings together leading academics and key industry partners in a shared vision to help define and develop the 5G infrastructure.

How did we solve it?
To take care of such complex and multidimensional task, we delivered service design as TOSCA blueprints together with plugin implementation in Python.
Confirming our industry standards expertise, Amartus team also developed a plugin compliant with TM Forum APIs: TMF641 and TMF638.
TMF641 is the REST API for Service Order Management that provides a standardized way for placing a service order with all necessary parameters. TMF638 provides a consistent mechanism for Service Inventory management.
Where’s the network innovation?
The most innovative part of the project was the 5G part, in which we orchestrated 5G Network Slicing to guarantee end-to-end QoS for real-time video streaming services.
Quality of Service (QoS) is a set of technologies that work on a network to guarantee its ability to dependably run high-priority applications and traffic under limited network capacity. QoS technologies accomplish this by providing differentiated handling and capacity allocation to specific flows in network traffic.
Here’s the scheme that illustrates the end-to-end solution architecture:
