Time critical applications, such as Trading Stock Exchange’s, Airport Terminals etc. require systems that deliver high throughput with low latency, as negligence even by a millisecond can prove catastrophic for business. Bearing in mind the Industry needs, Arastu Systems, a company that specializes in delivering customized IP solution in the Networking and Memory area, today announced Ethernet 10G Digital Switch IP soft core, which is proven and is readily available for usage.

The switch is highly configurable and can be easily customized as per the customer’s needs. The designed architecture for the IP is an optimized cut-through design which enables sub 100ns port to port latency. It easily fits into today?s ASIC and FPGA technologies with low gate count. The core can be configured to support 3 to 24 ports, where each port can act as 10M/100M/1G/2.5G/10G Ethernet with fully non-blocking switching. It also supports features such as software based Multi-cast grouping, VLAN, CAM/RAM based lookup and many more.

Additionally, the IP offers complete support for Layer 2 protocol based switching for Unmanaged Switch and Managed Switch, partial support for Layer 3 protocol and optional support for Precision time protocol (PTP) 1588.


The core fits to the serve the needs of multiple industries such as Industrial, Automotive, Audio Video Broadcasting. It also meets the requirements to fulfill various IoT (Internet of Things) applications on demand. Applications that use the wireless backhaul technology can also rely on Arastu Systems Ethernet solution to replace Application specific standard product (ASSP’s).
