Product or Product Family Name

Excelfore Ethernet Network Protocol Stacks

Product Summary

Excelfore has implemented Ethernet protocol stacks which have been integrated and deployed on numerous automotive production programs globally. Excelfore RTP protocol is believed to be the only commercially available RTP stack in production in the automotive industry. The Excelfore AVB stack was the first implementation to be certified by Avnu for both the ‘talker’ and ‘listener’ functions. The Excelfore AVB/TSN stack is running in cameras, video displays, head units, even ECUs. The Excelfore SOME/IP and DoIP stacks also run in network gateways so that CAN, LIN, and other automotive busses can be reached by Ethernet.
