A　real-time　telemonitoring　system　with　multi-physiological　parameters　based　on　the　Internet　is　designed.　The　system　consists　of　home　terminals　and　a　server.　A　home　terminal　consisting　of　a　PC　and　a　multi-parameter　monitor,　provides　physiological　monitoring.　A　server　is　a　powerful　computer　that　stores,　retrieves　and　processes　data　and　provides　P2P　index　service.　This　system　adopts　both　C/S　(Client/Server)　mode　and　P2P　(peer-to-peer)　mode　in　its　network　communications.　The　C/S　mode　provides　physiological　data　upload,　retrieval　and　download,　and　the　P2P　mode　provides　real-time　telemonitoring　and　video　chatting　between　doctors　and　patients.　Experiment　results　show　that　P2P　technology　could　improve　the　transmission　speed　of　Internet　network　and　realize　real-time　monitoring　of　physiological　parameters.
