He was at the same time (since 1971) employed at the equipment manufacturer Bolt, Beranek and Newman in Cambridge, Master of Arts, where he programmed the Interface Message Processor, work that in part led to his dissertation Adaptive routing for distributed computer networks advised by Jeffrey P. Buzen (1974), in which McQuillan developed ways to reroute messages around faulty and congested areas in the Internet based on delay feedback. These mechanisms were used in the first link-state routing protocols (1978). He also edited the two early introductions to networking, Understanding the new local network technologies (Bolt, Beranek and Newman Technologies, 1978) and A practical view of computer communications protocols (Institute of Electrical and Electronics Engineers, 1978).
He started McQuillan Consulting in Concord, Master of Arts (1982), became a columnist to Business Communications Review as well as an annual organizer of the Next Generation Network (NGN) conferences.
