These inefficiencies reduce the effective capacity of a 1200 baud channel to 300-500 baud. In order to correct some of these inefficiencies a few suggestions are offered. The UDP is a very small transport protocol, and as such does not provide absolute data integrity under all conditions. The TCP is a much more robust protocol, and as such is capable of assuring absolute data integrity through the network, with a much higher overhead. It was recognized that while AX.25 Level 2 provided a means of linking digipeaters, as packet radio activity grew, it would be more difficult to use this feature because of collisions.
Experiments Using virtual and datagram circuits are under discussion.
Some views on how Packet Radio could improve the delivery and efficiency of Distance Teaching in Less-Developed Countries. A review of packet growth since the Third ARRL Networking Conference is followed by a discussion of anticipated expansion of packet activity during the next year. A framework for orderly growth is presented, based on the above observations. Amateur radio operators in South Florida are exploring the capability of Packet Radio to provide the National Hurricane Center with high quality weather observational data, and in turn transmit timely forecast information from the Hurricane Center to effected areas. Routing in particular, has long been a fertile research area in computer networking.
