 Physical Network Functions (PNFs) are the traditional network functions that run on dedicated hardware appliances, such as routers, switches, firewalls, etc1. Virtual Network Functions (VNFs) are the network functions that run on virtual machines (VMs) on top of a common hardware platform, such as servers, storage, and network1. Cloud-Native Network Functions (CNFs) are thenetwork functions that run on containers orchestrated by Kubernetes on a cloud infrastructure1. The evolution of Network Functions reflects the trend of moving from hardware-centric to software-centric and cloud-based solutions, which offer more flexibility, scalability, and efficiency12. References: 1: Nokia Bell Labs Distributed Cloud Networks, Unit 2: Cloud Technologies and Features, slide 18 2: Nokia Bell Labs 5G Certification Program - Blended Learning, Section 2: Distributed Cloud Networks, slide 11

Network Service Orchestration is the process of managing the lifecycle of network services across multiple domains and technologies. It automates NFV service bydeploying, configuring, and scaling virtual network functions (VNFs) on demand. It is part of the 5G key enablers because it supports the dynamic and flexible provisioning of network slices and edge cloud applications. It does not increase operational complexity, but rather simplifies and optimizes it by using AI/ML and closed loop automation.

On-premise Edge Cloud and Metro Edge Cloud are the cloud deployments that provide the lowest latency. Latency is the time it takes for data to travel from the source to the destination1. On-premise Edge Cloud is a cloud deployment that is located within the premises of the end-user, such as a factory, a hospital, or a campus2. Metro Edge Cloud is a cloud deployment that is located within the same metropolitan area as the end-user, such as a city or a suburb3. Both On-premise Edge Cloud and Metro Edge Cloud reduce the distance and the number of hops that data has to travel, resulting in lower latency and higher performance4. Far Edge Cloud and Central Cloud are not the cloud deployments that provide the lowest latency. Far Edge Cloud is a cloud deployment that is located at the edge of the operator’s network, such as a regional data center or a base station3. Central Cloud is a cloud deployment that is located at the core of the operator’s network, such as a national data center or a cloud provider3. Both Far Edge Cloud and Central Cloud increase the distance and the number of hops that data has to travel, resulting in higher latency and lower performance4.
