DESIGNING TELCO NFVI WITH OPENSTACK

Abstract

The rapid evolution of telecommunications services necessitates the development of robust and efficient network infrastructures. This paper provides a comprehensive guide for designing Network Function Virtualization infrastructure (NFVi) with OpenStack to host Telco real-time workloads. It outlines key considerations such as performance and latency, resource isolation, high availability and redundancy, network virtualization, security, and scaling. Additionally, it delves into critical aspects of storage requirements, the use of Ceph as a Software-Defined Storage (SDS) solution, and detailed real-time communication considerations within NFVi using OpenStack. By addressing these considerations and leveraging the capabilities of NFVi, OpenStack, and storage solutions like Ceph, organizations can create a well-architected and reliable infrastructure that meets the demanding requirements of Telco real-time workloads. Regular testing, monitoring, and adaptation are essential for maintaining the performance and availability of the NFVi environment over time. This paper aims to serve as a comprehensive guide for network engineers, virtualization specialists, and Telco experts involved in the design and implementation of NFVi with OpenStack for hosting Telco real-time workloads.
