We have already proposed media cruising signaling protocol (MCSP) for high-speed resource reservation by controlling the link layer from the IP layer directly. Although it would be better to apply MCSP between terminals to make full use of the features of the resource reservation protocol, if media cruising (MC) is applied in an existing application, some problems occur. MCSP currently runs on FreeBSD, but is not implemented in other operating systems (OSs). In addition, ATM is used to control the quality of service with resource reservation, but ATM interface cards are only available for some OSs. To solve these problems, we propose an MC gateway that interfaces between a terminal and an MC network. This paper outlines MCSP and the MC gateway and presents experimental results for transferring moving pictures via a prototype MC gateway. These show the effectiveness of the MC gateway.
