About the whitepaper
Network Functions Virtualisation (NFV) has taken root in the production environments of telecoms operators. The individual components of NFV, known as Virtualised Networks Functions (VNFs), are critically tied to a general purpose operating system, as opposed to being integrated into application-specific devices.
This union makes performance and support of core operating system components, like the kernel, the foundational metrics of success. This special report will demonstrate that Ubuntu 18.04 LTS offers the necessary, proven reliability, while also offering supported kernel choices that enhance the efficiency of VNF operations and functions.
- A detailed analysis comparing real-time kernel assumptions against test results designed to reflect telco and NFV workloads (architectures, networking, FS, VM, compute...)
- A results comparison of the Ubuntu 18.04 LTS generic kernel 4.15.0-22-generic, the Ubuntu low-latency kernel 4.15.0-22-low-latency and an Ubuntu Linux kernel patched to be fully preemptive 4.16.0-rt4-PREEMPT_RT_FULL as well as preemptive with low-latency
- Which of the compared kernels provide the most balanced operational efficiency
