5G

We will cover a reference architecture for network slicing in this blogpost. 

3GPP as the foremost standards body driving network slicing defines the overall framework for Operators to provide customized network slice instances (NSI) that support various requirements/features. These include a Network Slicing management framework which this blog post will discuss. 

3GPP is the principal standards body driving 5G architecture and standards. It has defined various network slicing specifications in its various working groups.

s telcos and other CSPs begin moving to 5G RAN and 5G Core deployments, these are overwhelmingly based on Cloud-native microservice architectures, REST APIs, Kubernetes-based containers, and NoSQL databases for stateless architecture are commonly implemented in telecom networks. With this blog, we begin discussing life cycle management of 5G networks.

Prior to the advent of K8s and Cloud-Native functions, network functions (NFs) were primarily deployed by CSPs as a combination of physical appliances and some VMs.

To break this out into numbers, a typical CSP will deploy hundreds of thousands of network services as virtual network functions (VNFs) or CNFs. VNFs will run in virtual machines that can optionally be run inside a Kubernetes distribution.

Automakers, OEMs and ISVs are now realizing that cars are moving to a cloud native future. While 5G promises huge advances in business models, monetizing car data means investing in connectivity and software applications.

So far we have discussed 3GPP standards for 5G NR (New Radio) https://www.vamsitalkstech.com/5g/5g-new-radio-nr-platform-architecture/  and 5GC (Core)  https://www.vamsitalkstech.com/5g/5g-core-5gc-platform-architecture/ architecture. While all of the 3GPP releases till Release 15 assume that an…

The goals of the 3GPP are to standardize core functions in the SBA to be microservice and cloud-native. When the Telco cloud becomes ‘Cloud-Native’ and Stateless

We discussed the 5G Service Based Architecture in this post. CSPs know that 5G deployments will take both time and effort.
