Technica Realtek Partnership

Technica Switch Software Stack running in the Switch cores.

Technica Engineering and Realtek combine switch configuration, secure communication, and runtime management in one automotive Ethernet implementation. By running the Technica Switch Software Stack directly on the switch, the solution connects Configuration as Code with FLYNC, MACsec-secured communication, and Switch Management via SOME/IP into one consistent workflow for automotive Ethernet networks.

Talk to our experts

Modern automotive Ethernet networks require more than static switch configuration.

Engineering teams need a consistent way to define network behavior, deploy configurations, integrate security mechanisms and access switch functionality during operation. The joint Technica Engineering and Realtek implementation addresses these needs by combining:

FLYNC for structured network configuration

Automated deployment workflows

MACsec for authenticated
switch-to-switch communication

Switch Management via SOME/IP for runtime interaction

This creates a more integrated approach to switch software, helping teams reduce configuration complexity, and bring switch behavior closer to modern software-defined development workflows.

One stack for configuration, security and runtime management

The Technica Switch Software Stack, running on the Realtek switch, provides the software layer that connects switch configuration, deployment, and operation.

Instead of treating these as separate tasks, engineering teams can work with a more unified workflow:

Define configuration in a structured model

Deploy it in an automated way

Secure communication between switches

Access switch functionality during runtime

How the implementation works

From declarative configuration models to hardware-authenticated communication and dynamic management and monitoring of the switch.

STAGE 1

Configuration with FLYNC

Network and switch configuration are defined using FLYNC, enabling a structured and repeatable Configuration-as-Code workflow via an open-source solution.

STAGE 2

Automated deployment

Configuration changes can be validated and applied through an automated pipeline, reducing manual effort and helping teams maintain consistency between design and deployment.

STAGE 3

Secure communication
with MACsec

MACsec is used to establish authenticated communication between two Realtek switches. When the correct MACsec-enabled configuration is applied, the communication channel is established and traffic is forwarded. Without the required secure configuration, the channel cannot be established and traffic is blocked.

STAGE 4

Runtime Switch Management via SOME/IP

At the same time, Switch Management via SOME/IP provides access to switch functionality during operation, enabling interaction with the switch through a standardized interface.
