The UDP Offload Engine (UOE) IP Core allows for immediate operation at 10 or 25 GbE, while providing a simple path to 50/100 GbE.
The UOE IP core implements the UDP standard RFC 768, including checksum, segmentation and reassembly hardware offload. This offloads much of the work described in RFC 768 from software to hardware. In doing so, line rates of 25, 50, and 100 GbE are achievable.
The UOE IP core enables application-level UDP datagrams to be concurrently sent and received on a LAN or across a network. An integral IGMPv2 multicast pre-selector removes unwanted traffic, and L4 UDP multicasts are pre-selected so that user applications don’t have to perform this function. The UOE IP core is tested for operation with popular FPGA vendors’ 10 GbE and 25 GbE Ethernet MACs.
