Design and manufacturing of telecom equipment
Networking hardware and equipment
We design bespoke hardware and network appliances for high-speed data processing:
- End-user equipment: CPE, routers, residential gateways, set-top boxes, home networking adapters, wireless AP, and thin clients.
- Ethernet switching: stackable and managed access switches, Сarrier Ethernet switches/routers/gateways, security appliances, aggregation switches and routers.
- Industrial network equipment and industrial Internet of Things (IoT): switches for industrial process control, transportation and automotive applications, smart grid energy distribution.
- Custom FPGA network cards for broadcast video, high-performance computing, AI, and data-center applications.
Our developments meet high requirements for data network bandwidth capacity.
I want to mention the high level of proficiency of Promwad. They developed excellent technical solutions in full compliance with the specifications. Transparency of company processes made a very favourable impression.
- Development of system drivers for network chips, wire and wireless interfaces
- Optimization of the network stack for a hardware platform
- Development and upgrade of Linux-based software for L2 switching and L3 forwarding with VLANs, flow control (802.3x), flow/port mirroring, IGMP snooping, GVRP, etc.
- Design of user interfaces and applications for managing network devices and infrastructures via web GUI, command line interface (CLI), simple network management protocol (SNMP), telnet server, JSON RPC, etc.
- Development of VoIP solutions, including SIP user agents with hardware-accelerated audio/voice processing
- Remote desktop software integration: implementation of RDP, Citrix ICA, and VMwareP CoIP protocols
