A plug and play scheme for IP based devices and their failover schemes for quality of services includes establishing a infrastructure in the Internet so that the IP based devices can be plug and play in the present or oncoming Internet. Through the Dynamic IP and the Internet, a visitor can connect with an IP based device by broadcasting and send or receive information without going to through servers so that the data traffic in the Internet will be reduced. Additionally, with a plurality of the bridge servers being backup with each other, the transmission quality can be insured by means of automatic data transmission through the bridge servers if the connection between the visitor and the IP based device breaks. Furthermore, the infrastructure includes several failover ways to ensure the link between the visitor and the IP based device and reduce the risk of losing connection with the Internet.
