Ethernet switching

We design Ethernet switching equipment which serves as an integral part of any intelligent network. Our goal is to make them as non-blocking and scalable as possible. Among the examples of Ethernet switching devices are:

  • stackable & managed access switches 
  • carrier Ethernet switches/routers/gateways
  • security appliances
  • aggregation switches & routers

Industrial network equipment and IIoT

We design extensible switches and routers for the industrial Internet of Things industry. They support auto-configuration, address learning, forwarding and filtering, and special means to handle Quality of Services or QoS. Clients use them in factory automation, smart grids, etc. The examples are:

  • switches for industrial process control
  • transportation and automotive applications
  • energy utility networks or smart grid distribution

Selective Q-in-Q

SDK: Microchip IStaX-APPL-2020.09.

Tested on a PCB135 debug board from Microchip on VSC7558. Q-in-Q operates on the Sparx-5 microprocessor family.

Description: Selective Q-in-Q determines the pairing of a given client VLAN (on the UNI side) and the sought S-VLAN identifier. The S-VLAN identifier is joined to the input unmodified C-VLAN, and the packet is forwarded across the ISP's double-tagged network. The S-VLAN ID is removed from the output, and the client VLAN ID is retained in the packet. Packets that do not match the specified client VLANs are discarded by default.

Get access to our CoreKnowledge in telecom

Problem

Working with several contractor partners in network switch design projects to obtain the necessary expertise always leads to complications and slow communications and eventually increases labor costs.

Benefits

We conducted an internal analysis of all our projects (their number is +350) and noticed an increase in mixed project teams by at least 13-27%, depending on the number of members. According to statistics, the average volume of such projects is about $146,000, and the client's potential savings are up to $19,000.
