Micro-Service Mesh

Envoy/Istio Sidecar Infrastructure in 6GC

A dedicated communication layer managing service discovery, encryption, load balancing, and observability across thousands of containerized core microservices.

Technical Explanation

As the 6G Core transitions into fine-grained microservices, managing inter-service communication becomes critical. The Micro-Service Mesh deploys high-performance sidecar proxies (like Envoy) alongside every network function container. The sidecars transparently encrypt all traffic with mutual TLS 1.3, balance traffic across replicas, inject fault-tolerance retries, and export real-time OpenTelemetry distributed traces without altering application code.

Key Functions

  • Transparent mutual TLS 1.3 encryption across all internal core microservice traffic
  • Dynamic client-side load balancing and intelligent retry policies for failed requests
  • Distributed tracing exporting end-to-end transaction latency breakdowns across microservices
  • Fine-grained access control policies enforcing zero-trust micro-segmentation
  • Zero application code modifications required to implement advanced routing logic
