Cloud Native Telco Day Europe 2022

In this session, Daniel Bernier will be demonstrating how Cilium and its eBPF data plane was extended to support telco networking requirements in a cloud-native way. He will demonstrate how Cilium can provide network segmentation and Multi-VRF support with or without the use of multiple interfaces. With this new approach, he will also explain how to build simple multi-cluster VPN or simple integration to an MPLS provider network by leveraging natively IPv6 and SRv6.

Network Service Mesh (NSM), a CNCF sandbox project, offers a framework for building network services that addresses current networking challenges for Telco Cloud-native Network Functions (CNFs) deployed on Kubernetes. What does this imply? And how can NSM be brought in for advanced use-cases? This speech will present a framework for network services extensions using NSM as foundation for addressing the networking challenges seen around Telco CNFs. Such CNFs inherently have high demands on networking capabilities such as VPN e2e network separation & isolation, connectivity through acceleration hardware, L3 forwarding and LB of Telco protocols as a Service (aaS). In addition, Telco CNFs require scalability and high availability. The design is realized by the open-source Meridio project published on GitHub. Issues related to NSM found during the implementation; and how they have been addressed by the community will be put forward.
