On May 22 at 9:15 am PDT, Perlman will participate in a plenary session on the technology’s early history. Perlman is the inventor of many fundamental technologies in computer networking including the spanning tree algorithm which is at the heart of today's Ethernet. Intel was one of three companies to initially promote Ethernet as a standard. Forty years later, the standard continues to help spur innovation.
