Embodiment Construction

[0057] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0058] With reference to Fig. 5, the resource allocation method of bus system according to the present invention comprises the following steps:

[0059] Step S102, all nodes respectively select a resource from the available resources, and all common nodes send response messages respectively;

[0060] Step S104, the master node judges whether there is a node that selects the same resource at the same time, if not, completes the resource allocation, and if exists, proceeds to step S106;

[0061] In step S106, the nodes that have selected the same resource reselect a resource from the unselected available resources, and send response messages respectively, and return to step S104.

[0062] After the resource allocation is completed, the master node can renumber and allocate resources according to the resource allocation situation, and distribute new resource alloc...

Abstract

A method for distributing resource of bus system includes selecting one resource from available resources separately by all nodes and sending response message separately by all normal nodes, judging whether it is existed that nodes of the same resource are selected simultaneously or not by master node, finalizing resource distribution if it is not or otherwise reselecting one resource separately from available resource being not selected by nodes selected the same resource and sending response message separately then returning back to judging step.

Description

technical field [0001] The invention relates to bus communication technology, in particular to a resource allocation method of a bus system. Background technique [0002] The concept of a home network has been well known many years ago, but so far, there is no set of real home network-based products put into large-scale use. The main reason is that there is not yet a suitable set of physical layer protocols for home networks that have been formulated. At the same time, due to the rapid development of communication technology and audio and video codec technology, the concept of home network is not only the communication network of control and security, nor the communication network of simple high-speed video stream or access, but It is an integrated and comprehensive network system. [0003] From the perspective of application, a home network should have the following characteristics: ease of use, compatibility, and robustness. From the perspective of communication technol...
