5G

We briefly discussed the benefits of slicing from a 5G operator POV. Let us consider the top benefits of this technology from an Operator Standpoint.

Network slicing should be thought of as true business-level virtualization for 5G networks. Operators will be able to share the same 5G physical infrastructure among many multiple tenants – 5G service operators, enterprises and consumers.

The goal of 5G deployments is to provide consumers and business users with highly engaging experiences that leverage the high reliability and high performance provided by the underlying network.

5G applications will all be about low latency and fast data processing at high throughput. These will include not just the wireless core, radio applications but also custom workloads such as video streaming, VoIP, etc. Along with SR-IOV, DPDK is a high-performance option that enables the industry to move latency-sensitive applications to the cloud.

5G use cases need direct connectivity between CNFs (Cloud Native Functions), running on Kubernetes pods,  and physical NICs. SR/IOV has been used for quite some time and thanks to plugin contributions from Intel and others, it is now available for enterprise use.  

This post discusses how to overcome the first limitation of K8s from a 5G standpoint – enabling pods to assume multiple network interfaces. 

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…
