The Router in a Container (FRR + Linux Kernel VPP)

Running traditional, resource-heavy Virtual Provider Edge (vPE) software routers inside cloud-native Kubernetes environments consumes massive amounts of host CPU, increases system boot times, and slows down application packet processing speeds.

⚠️ The Performance Drop: Standard Linux kernel networking is structurally unsuited for processing packets at 100G+ line rates because it triggers a continuous stream of hardware interrupts and CPU context switches for every single packet passing through the stack.

🚀 The High-Propulsion Container Edge: SRv6 Tek Innovations bypasses standard kernel limits by deploying a containerized Router-in-a-Container stack using FRRouting (FRR) and FD.io Vector Packet Processing (VPP).

Our cloud-native routing architecture optimizes container host efficiency:
➡ Vector-Based Packet Processing: VPP processes packets in groups (vectors) rather than hop-by-hop, maximizing CPU L1 cache utilization and unlocking terabit forwarding speeds on standard x86 servers.
➡ FRR Control Plane Alignment: FRRouting runs as a lightweight microservice inside the container, managing IS-IS and BGP extensions while loading SRv6 uSID instructions directly into the VPP data plane.
➡ Zero Interrupt Overheads: VPP uses high-speed Poll Mode Drivers (PMD) to read packets directly off the network interface hardware, bypassing the host kernel entirely to save processing cycles.

Deploy enterprise-grade routing capabilities directly inside your application containers without sacrificing performance.
