Network for Block Switching of Data

This paper describes a possible sort of data network for the transmission of addressed blocks of data between data terminals. The network consists of a number of closed rings or loops around which data blocks circulate. Data terminals on local loops can read data into empty blocks and read data addressed to them from full blocks. Buffered devices transfer data between local and regional loops and between regional loops and a national loop. Loops so interconnected need not be synchronized; they need not even operate at the same bit rate. Provisions are made for a “busy” signal, for special loops to carry heavy traffic between particular local loops, and for alternate routing.
