Table of Contents


ZIGGO is a flexible, standard-compliant, and control-function-virtualized TSN switch platform ready for industrial control, automotive electronics, and other time-sensitive applications.

This is the document for the ZIGGO CaaS Switch. (We also offer ZIGGO-Device that comply with the IEEE 802.1 TSN standard.)

ZIGGO Open Platform

The construction of the ZIGGO Open Platform consists of three levels: network device, management tools, and a Demo App. More details in ZIGGO-Device.


We provide a demonstration video of the TSN switch. It demonstrates the superior performance of the ZIGGO-CaaS-Switch compared to the normal switch.

The left side of the picture is the ZYNQ development board we use, and the right side is the TSN display board we built.

  • ZIGGO supports the simultaneous transmission of both Information Technology (IT) and Operation Technology (OT) data traffic with QoS guarantee.

  • ZIGGO complies with IEEE standards 802.1AS, Qav, Qbv, and Qcc.

  • ZIGGO provides Real-time and Deterministic Ethernet transport

    • ZIGGO achieve Zero Packet Loss , Microsecond-level Latency with Nanosecond-level Jitter Gate Ability.

    • ZIGGO guarantee Gigabit Throughput.

    • ZIGGO provide gate accuracy applicable to All Ethernet Frame Sizes.

Read before start

Getting started with ZIGGO-CaaS-Switch/ZIGGO-Device is a pretty hard task. Users/developers need to have sufficient basic knowledge and be prepare to for a long periond of learning and debugging.

Please refer to basic_knowledge.md to check if you have ability to use ZIGGO competently.

Getting Started

Please refer to required.md to get prepared.

Please refer to hardware-build.md for the build hardware for ZIGGO Evaluation Toolkit and software-build.md to run time synchronization logic and set up TSN GCL .

System Design

ZIGGO is implemented on ZYNQ-7000 SoC and exploits ZYNQ’s both hardware and software programmability.


We also provide more in-depth documentation explaining specific design principles for ZIGGO CaaS Switch.

Demo APP Tutorial

We also provide a testbed build document(in ZIGGO Device) that allows you to build a real-time Ethernet system using the ZIGGO swtich and ZIGGO Device.

Through this platform, we can measure the delay and jitter of TSN time-critcial traffic, the switch’s gating capability, bandwidth guarantee and gating accuracy.

Replacing ZIGGO CaaS switches with commercial TSN switches can also test its above capabilities.

  • ZIGGO CaaS Switch Release

  • ZIGGO Evaluation Toolkit Release

  • ZIGGO Evaluation Toolkit Source Code

  • Tutorial for build a testbed

  • Test Case for TSN

We will expand each test in the tutorial to multiple test cases to cover different edge cases and comprehensively test the performance of TSN switches.

  • Support Device List

At present, we have only tested our own Ziggo switches and are testing other commercial switches (such as Huawei ,H3C and NXP). We expect to maintain a list of test results in the future.
