Embodiment Construction
[0018] An embodiment of the present invention provides a token passing method applied to a family, which will be described in detail below.
[0019] In this token passing method, each slave node has its own priority, and the MAC address is globally unique. It is determined when the device is produced. The priority is determined by default according to the service type, and can be set by the user. The priority of the master node is fixed at 0. It should be noted that, in a digital home network, the master node is a home gateway, and the slave nodes are various application terminals connected to the home gateway in the home, such as computers, telephones, televisions, game consoles, security equipment, meter reading Collector etc.
[0020] The token passing method can realize the identification (ID, IDentity) division of the slave nodes controlled by the home gateway; realize the access of 6 kinds of services (expandable to 16 kinds of services at most) and 64 home service termi...
