Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] An embodiment of the present invention provides a method for constructing a multi-tree topology. The method constructs a multi-tree topology based on the uplink bandwidth information of nodes, which makes it easy to control the depth of each subtree of the multi-tree topology, thereby helping to improve the efficiency of the multi-tree topology. transmission efficiency. like figure 2 As shown, the specific steps of this embodiment are as follows:

[0028] 101: Determine the role of the node according to the upstream bandwidth information of the node, and determine the subtree to which the node belongs according to the principle that the upstream bandwidth of the subtree is equal or similar.

[0029] The specific method is: th...

Abstract

The invention discloses a method for constructing multi-tree topology and a root node, belonging to the field of network management. The method comprises the steps: confirming the role of the node according to uplink bandwidth information and confirming a subtree that the node belongs to according to the principle that subtree uplink bandwidths are equal or similar; and confirming the position ofthe node in the subtree that the node belongs to according to the uplink bandwidth information of the node. The root node comprises a role confirming module, a subtree attribution confirming module and a position confirming module. During constructing multi-tree topology, the method takes the uplink bandwidth information of the node into consideration and regularly distributes nodes into each subtree according to the uplink bandwidth information of the node, thereby ensuring that the depth of the subtree of the multi-tree topology is easy to control and further being beneficial to improving the transmission efficiency of the multi-tree topology.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method for constructing a multi-tree topology and a root node. Background technique [0002] With the continuous development of broadband multimedia networks, various broadband network applications emerge in an endless stream. Broadband applications such as Internet Protocol Television (IPTV), video conferencing, data and material distribution, network audio applications, network video applications, and multimedia distance education all pose challenges to the carrying capacity of existing broadband multimedia networks. Traditional networks built with unicast technology can no longer meet the requirements of emerging broadband network applications in terms of bandwidth and network service quality, followed by problems such as network delay and data loss. Therefore, the IP multicast technology is introduced to solve the above problems. IP multicast technology is an important e...
