Network Service Mesh to Address Cloud Native 5G Telco Networking Challenges
Explore how Network Service Mesh (NSM) addresses cloud native 5G telco networking challenges in this 40-minute CNCF conference talk. Dive into key networking issues faced by cloud native telco applications, including VPN/traffic separation, NAT-less protocols, and legacy protocols. Learn why Kubernetes networking falls short and how current approaches like Multus, Danm, and CNI-Genie only provide node-level solutions. Discover NSM's potential to decouple infrastructure from applications and its ability to handle complex multi-network clusters. Gain insights from a proof of concept demonstration and ongoing work with the CNF test bed network separation use case. Explore topics such as Network Functions, Telco Interfaces, Traffic Types, and the Decision Graph for implementing NSM. Understand the implications of adding SCTP to Kubernetes and using VLAN for 5G. Address questions about scalability, additional services, and public IP evolution in the context of cloud native 5G networking.
