Network switch

Managed gigabit switches for industrial and telecom applications

Since 2004, Promwad has been helping customers to be on the cutting edge of telecommunication technologies, creating for them new network appliances, NIC and embedded software.
Our telecom R&D unit has hands-on experience with network switch technology and switch SDK from leading chip vendors. We are vendor agnostic and have an unbiased point of view on different switch hardware.
We do
  • bespoke board design of multi-port (8/16/24/48) gigabit network switch with uplinks and specific interfaces required by customer
  • network system-level software on top of Microsemi IStaX
  • network system-level software on top of Marvell CPSS (Prestera Software Suite)
  • utilize switchdev
  • new Linux kernel driver model for Ethernet switches
  • ONIE (Open Network Install Environment) customizations and installation on target network switch board/hardware
  • SONiC (Software for Open Networking in the Cloud) porting to different switch platforms
  • OpenSwitch software development
