Todd has been active in the development of reliable multicast software since his early research work in reliable multicast as a graduate student at West Virginia University. Todd’s knowledge of reliable multicast was important in his work with NASA in 1994 and 1995. In 1995, Todd co-founded GlobalCast Communications in Fremont, CA. During his 4 years with GlobalCast, Todd implemented a number of reliable multicast protocols including a prototype of PGM and commercial releases of RMP and Lucent’s RMTP II. These protocols employed different methods of packet recovery, and both had clear strengths and weaknesses. GlobalCast was acquired by Talarian and at that time Todd joined the WhiteBarn team to develop a commercial PGM product as well as reliable file transfer applications built on this framework. In this work, Todd helped shape the PGM specification submitted to the IETF as a co-author of draft IETF RFC 3208. When Talarian acquired WhiteBarn, Todd continued to drive the PGM development effort as well as support the integration of PGM into the Talarian SmartSockets product family. Todd continued in these roles after the acquisition of Talarian by TIBCO. In early 2004, Todd left TIBCO to join the 29West team. |
