Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Node frame diagram of the present invention is as attached figure 1 As shown, its information database includes a priority table and a path information table. The priority table is to store the priority of the existing services being transmitted, including those on the shortest path and those on the suboptimal path. The priority table provides priority determination and comparison for incoming services, and then determines whether the service should be diverted to the optimal path or the sub-optimal path.

[0037] The path information table is when the network starts to run, each node sends messages to each other, and the shortest path to each node is obtained through self-learning. During the running process, the path information table itself is constantly updated, and the suboptimal path to each node is saved when updating. This ensures that the shortest pa...

Abstract

This invention provides a QoS protection method for a digital family network, which defines the optimum path for data transmission in the network, in which, two communicating sides transmit a conventioned data packet with the best priority before beginning transmitting data and the data packet determines the service parameter and transmitted priority needed by data transmission then the network assings a bandwidth for the data transmission on a best path based on said priority and the service parameter to guarantee the transmission quality in a digital family network.

Description

technical field [0001] The invention belongs to the technical field of digital home network, in particular to a method for QoS guarantee of digital home network. technical background [0002] Digital home network refers to a new technology that connects PCs, home appliances, security systems, lighting systems and wide area networks within the scope of the home and can be extended to neighbors and communities. The purpose is to realize information sharing between PCs, home appliances and other tools, and cooperate with each other so that users can easily grasp the situation of home equipment and make home equipment better serve users. [0003] Digital home network is a concept that has emerged in recent years. With the development of 3C fusion technology, digital home network has attracted more and more attention and attention from the industry. The so-called 3C integration refers to computers (Computer), communications (Communication), and consumer elect...
