Abstract
One important and widely used mechanism to make data transmission more efficient is streaming. Transmitting geographic information using streaming mechanism can be designed and implemented at several levels according to granularity of data to be transmitted. An efficient transmission method is suggested based on a streaming mechanism of which transmission unit is a block or a page. Using the proposed concept, the concept of data streaming which is tightly coupled with operating system is introduced, design of the streaming system is described and some experiments are conducted to showthe performance of the designed system.
