Measurement of host costs for transmitting network data

The protocol with RJS at UCLA requires that all programs and data to be transmitted on the data connection be blocked[2]. This means that we simulate records and blocks with special headers. This we found to be another problem because of the computation and core space involved. This computation took an appreciable amount of time and core space we found because of our real core size that we were being charged an excessive amount due to page faulting. The page faulting also reduced our real-time transmission rate to the extent that we
