What is SYNESIS?

SYNESIS is a packet capture appliance developed and manufactured by TOYO Corporation. SYNESIS captures all the traffic without any packet loss and enable to visualize the traffic.

If you have trouble in the network, SYNESIS support for prompt trouble shooting.

Can we see the demo?

Yes, possible.

Please contact your sales or send your request to

We use Wireshark. What is the differences between SYNESIS and Wireshark?

SYNESIS is a dedicated packet capture appliance which consists of hardware(parts) and software. Therefore, SYNESIS hardware is highly optimized to SYNESIS software to be a best system. While Wireshark is software only, you use it with your own PC or you need to find out the suitable hardware.

The data which SYNESIS captures is effectively/automatically saved in the storage without any packet loss, even at a high data rate. SYNESIS is suitable for full capturing of higher traffic(1 GbE or above), which cannot be realized by Wireshark.

Please let me know the basic workflow and the schedule until the actual deployment of SYNESIS.

A few months needed for delivery at a customer site after an order is placed with TOYO.

(It can be discussed by area and project status)

The number of packets from the packet generator does not match the number on the counter of SYNESIS

The statistical information such as the number of packets start counting after 2 seconds later from the start of capture.  Please start the packet generator after starting capture.

Does SYNESIS support redundancy ? /SYNESIS has two power modules. Is it possible to start SYNESIS with only one power module connected to the electric outlet (in the case of distributed model)?

All the model of distributed type has 2 power supply modules supporting redundancy.

The second power module is provided for redundancy.It is possible to operate SYNESIS with only one power module connected to the electric outlet.


However, when the power unit fails or the power cable is unplugged , SYNESIS turns off immediately, which may lead to hardware failures or loss of data.  Therefore, we recommend supplying power to the two power modules constantly.  This is also preferable in terms of from the viewpoint of optimization of power efficiency.”

How does SYNESIS calculate the line utilization rate?

SYNESIS calculates the line utilization rate based on the number of received bytes and the number of received packets which are acquired from the capture card.


Every second, SYNESIS acquires from the capture card the number of received bytes and the number of received packets.  Then, SYNESIS performs the calculation below.  IFGs and preambles are included in the calculation.
{(Number of received bytes + 20 * number of received packets) * 8 / line speed (bps)} * 100

Is it possible to update the OS security patches and kernel by myself?

You can apply for yourself the security patches and kernel that are provided by TOYO.  If you apply any other security patch or kernel, we decline to offer any guarantee of correct operation afterwards.  In principle, we ask customers to perform update work for themselves.  We will provide manuals for the purpose.
