Abstract(in English) Ethernet is based on CSMA/CD(Carrier Sense Multiple Access with Collision Detection)protocol. Although this protocol is widely used in local area networks(LANs), it has a problem. The throughput and packet-delay performances degrade rapidly when the offered loads of packets become high. As a solution to the problem, we have proposed CSSS/OD(Carrier Sense Spread Spectrum with Overload Detection)protocol, which is a DS/CDMA(Direct Sequence/Code Devision Multiple Access)based protocol with a carrier sensing function and changes the spreading factor adaptively depending on network loads to improve the conventional Ethernet's performance. In this paper, we propose a stream data gateway as its application, and show its preliminarily examined performances. The gateway is assumed to relay stream data such as voice and video from their servers in the Internet to a 10BASE2-Ethernet segment where clients are connected.
