Dynamic allocating an optimum packet size for Chinese Teletex transmission

Summary form only given, as follows. Consideration is given to the effect of grouping data into packets for transmission in an error detect-retransmit system: the Chinese Teletex System. Since the error condition of the transmission line does not remain the same during the whole process of transmission, it is not possible to achieve a high throughput with fixed packet size. For the same error condition of the line, the bigger the packet size, the bigger the packet error probability; therefore more packets will have to be retransmitted. A method of dynamically allocating an optimum packet size to obtain a high throughput is presented. This is different from the approach used by R. Lynn Kirlin (1969) and Wesley W. Chu (1974).
