Solution Overview

The Automobile Electronics Division of DASAN Networks has been developing in-vehicle ECUs, including infotainment systems, for global automobile manufacturers.
We are expanding our technical know-how to the automobile sector as Korea's No. 1 internet communication equipment company by combining accumulated network technology with automotive technology and creating synergy effects.

Ethernet-based camera solutions enable easy installation, operation, and diagnosis through bidirectional communication. In this regard, the built-in Broad R-Reach PHY technology provides greater resistance to signal degradations such as crosstalk.

AVB switches provide rich features for best deployment as a core bridge connecting Ethernet-based ECU devices, such as stream scheduling, bandwidth shaping, priority-based forwarding, auto-configuration of IP/MAC address pairs, and electronic powering to enhance cameras.

A gateway function built on top of the switch enables communication between the CAN and Ethernet domains. For inexperienced drivers, the parking assistance system is especially helpful. To provide a "top view," DASAN Networks' AVM combines and processes real-time video streams from the front, back, left, and right cameras. We intend to offer "all Ethernet" in-vehicle communication, starting with infrastructure and ending with services.

Automobile Ethernet Software

It is simple to satisfy market demands thanks to the reliable and verifiable software components provided by automotive Ethernet software modules. With more services (AVB, SOME/IP, UDS on IP, etc.) available, our automobile Ethernet software primarily focuses on Ethernet-based networking and applications.

Automotive OEM, Tier 1, Tier 2, and in-house products have all been equipped with the Ethernet software stack from DASAN Networks (L2 switches, Ethernet cameras, AVMs, and Ethernet test equipment).

Key Features
  • AVB framework
    Mission-critical applications using time-synchronized audio and video transmission bandwidth scheduling and car shaper (CBT) IEEE802.1AS master/slave time synchronization mode, BMCA, 61883 encapsulated in Avnu IEEE1722 packets (PCM audio, MJPEG/H.264 video) Playback of media at presentation time via stream media clock recovery
  • IP framework
    Transmission of data packets between service-oriented, plug-and-play (SOMEIP) standards-based diagnosis IP and CAN in accordance with interaction functional rules (firewall, NAT, etc.)
    NXP's designated packet forwarding engine for the DoIP (ISO-13400-2) protocol stack (PFE)
  • Security framework
    Lightweight authentication using CCM8, GCM, and CBC in block cipher mode and based on the elliptic curve (AES128, ARIA) The interoperability function IWF between CAN and IP is implemented using minimal logic with no additional burden on a custom SoCCPU. Perform IWF on NXP's designated SoC (LLCE). Data forwarding between CAN-to-CAN and CAN-to-IP Support for data collection and filtering
Evolving Framework

Contrary to class AUTOSAR, AUTOSAR-Adapting is a mainstay of automotive software frameworks and offers a robust feature set. In addition, mission-oriented services can be implemented on application processors in real and virtual operating environments with POSIX based on API interoperability, APP execution in RAM, MMU-controlled virtual memory usage, service-oriented communication, multiplex and dynamic scheduling, etc (PSE51).

  • Framework extension
    Integration of platforms based on ARA: Simple transition from Comm's internal architecture to AUTOSAR (Framework bridge – Mesh controller)
    Supports the coexistence of multiple frameworks in Q1 2021
ODM Business

Since 2013, DASAN Networks has been developing AVB stacks for the automotive industry. Our Ethernet AVB stack is compatible with BCM89xxx, OSEK OS, and Linux. Implementations of IEEE 1722a AVTP, IEEE 802.1AS, 802.1Qav, and 802Qat are included in this AVB stack.

Functions for the TCP/IP stack, SOME/IP, SOME/IP SD, DoIP, and UDS are continuously being added as new implementations. We have the resources and personnel to create CAN to Ethernet gateways, AVMs, Ethernet cameras, automotive Ethernet switches, and more.
