In April 1962 Leonard Kleinrock published "Information Flow in Large Communication Nets" in RLE Quarterly Progress Reports. This paper, written in May 1961 as a proposal for his PhD dissertation, was the first publication to describe and analyze an algorithm for chopping messages into smaller pieces, later to be known as packets. Kleinrock's MIT doctoral thesis, Message Delay in Communication Nets with Storage, filed in December 1962, elaborated on the impact of this algorithm on data networks. (See Reading 13.3.)
