Network Service Mesh Solving Cloud Native IMS Networking Needs

Abstract: With the growing demand for mobile networks and specially IPMultimedia subsystem (IMS), new cloud native orchestration tools providing more flexibility and efficiency start to be used within telecommunication companies in order to improve the robustness and the reliability of these systems. However, Kubernetes, the most used among cloud native orchestration tools does not fulfill completelyall the needs and use cases in terms of networking the telecommunication industry meets. Network Service Mesh (NSM), a new Cloud Native Computing Foundation (CNCF) project, aiming to address complex networking use cases in Kubernetes might solve the different issues IP multimedia subsystem face. Detailed designs and implementations using Network Service Mesh coupled with diverse networking technologies are shown in this thesis with the objectiveof solving the networking IP multimedia subsystem requirements (e.g. the NAT issue and the secondary network). In addition, an analysis and an evaluation of Network Service Mesh is given together with a presentation of the ability of this new project to bring solutions toIP Multimedia subsystem based on a cloud native technology.
