Interoperability with the Internet Protocol

The UDP/IP core implements the UDP/IPv4 standard RFC 768/791, including checksum, segmentation and reassembly hardware offload.

The UDP/IP core is tested for operation with popular FPGA vendors’ GbE Ethernet MACs.

Increase data transfer rates to 50/100/400 GbE without starting over

Allows for immediate operation at 10, 25 or 40 GbE, while providing a simple path to 50/100/400 GbE.

Offloads all UDP operations so you can work with datagrams

Offloads UDP standard RFC 768 from software to hardware.

L4 UDP Multicasts are pre-selected so that your application doesn’t have to perform this function

An integral IGMPv2 multicast pre-selector removes unwanted traffic.
