Type of service wide area networkingA variety of long-distance types of circuits can be used for data communication. A description is given of an experiment which optimizes the simultaneous use of terrestrial and satellite circuits in a TCP/IP network. Traditionally, it has been difficult to use effectively the full capacity of high-bandwidth satellite circuits, due to long round-trip times coupled with TCP window-size limitations. The experiment significantly reduced the problem, and the result was effective use of all the available bandwidth and a satellite circuit for a single data transfer. This experiment also demonstrates the use of multiple T1 communication lines and type of service networking over these lines.
