Panel: Are Cloud Native 5G Core Network Functions (NFs) Truly Manageable & Secure? – Ramki Krishnan, VMware; Srini Addepalli, Intel; Heather Kirksey, The Linux Foundation; Tom Kivlin, Vodafone; & Balaji Ethirajulu, Ericsson
In the transition towards Cloud Native, 5G Core NFs has an interesting architectural mix of HTTP 2.0 and other network I/Fs. In this panel, we first examine the various manageability/security/visibility challenges of the 5G Core NFs in K8S with 1) Multiple network I/Fs for high performance data plane NFs and for isolation for all NFs 2) Chaining of NFs that are distributed across K8S clusters. While multi-cluster L7 Service Mesh (Istio, Linkerd etc.) seems to be a reasonable solution choice especially for HTTP-based functions, there are unique challenges posed by other NFs operation with other protocols and at lower layers. We will explore options such as an integrated Layer 2-7 service mesh approach leveraging open source efforts such as Open Virtual Network (OVN) to address these challenges – e.g. inter node/cluster secure communication using for Layer 7 TLS or Layer 2-4 IPSEC.
