About the Author

Francesco DiMambro (frank.dimambro@sun.com), has a Bachelor of Engineering degree with Honors in Information Engineering from Strathclyde University, Scotland and a Master of Engineering degree in Digital Systems Engineering from Heriot-Watt University, Scotland. The first company to utilize his talent beginning 1991 was National Semiconductor, in their Local Area Network division. There he developed NDIS 2 Ethernet network device drivers, which were used in MS-DOS, OS/2 (LAN Manager products) and Windows operating systems. In 1995, he moved from Scotland to California and started NDIS 4 device driver development for Infra Red wireless communication devices operating primarily on Windows 95, 98, and NT.

In 1996, he joined Sun Microsystems, Network Products Group and began supporting the Solaris Ethernet device drivers for Sun. He quickly moved to understanding the Sun Ethernet controllers and the performance factors associated their network device driver implementation. That experience prepared him for the task of developing the next-generation gigabit Ethernet device driver for the GigaSwift Ethernet product line.

Sun Ethernet driver performance has been his primary goal, while also increasing device driver quality and usability. With those areas in mind, he has filed eight patents, and with this first article, marks a new adventure in helping users maximize performance of an Ethernet NIC interface.
