Embodiment Construction

[0044] The scheme of the present invention can be briefly described as: select a central node from each node, and the central node allocates resources for the current service requests of the remaining nodes, and periodically updates the central node according to the operating status, and the new central node provides the resource allocation for the remaining nodes. The current business requests resource allocation. This solution can flexibly reorganize the network bandwidth resources, so that the network bandwidth resources are allocated on demand, avoiding the problem of network congestion in the prior art, although the transmission path has been minimized; and the central node itself is It is dynamically adjusted, taking into account the actual transmission status of the network, so that the narrowband network can meet the needs of large-traffic data transmission services; the specific plan is:

[0045] (1) Calculate the closeness of each node in the routing domain, and use ...

Abstract

The invention discloses a management method of bandwidth resources of a narrow band network, which comprises the following steps of: (1) calculating the compactness of each node in a routing domain, and taking the node with the biggest compactness value as a central node; (2) taking the central node as a temporary resource manager to manage the current bandwidth resources of the whole network; (3) recalculating the compactness of each node in the routing domain according to cycle, re-determining the central node according to the calculated node with the biggest compactness value, and repeating the steps (3) and (4). The management method has the advantages that: in the method, a flexible recombination strategy is adopted for the network bandwidth resources, and the central node is used for deploying the network bandwidth resources as required, so the method has the capacity of adjusting the resources of the whole network, has very low network management cost, and can realize large-traffic data transmission services in the narrow band network.

Description

technical field [0001] The invention relates to a communication technology, in particular to a method for managing bandwidth resources of a narrowband network. Background technique [0002] The traditional routing protocol adopts the shortest path algorithm, which does not fully consider the bandwidth utilization rate on the service transmission path, and does not have the ability to adjust the resources of the entire network. Re-occurrence of congestion, while other links are in an idle state, affecting the overall performance of the network. In narrowband networks, it is difficult for narrowband links to support the transmission requirements of large-flow data services. Therefore, the aforementioned problems are more prominent in narrowband networks. [0003] Using the TE extension of OSPF to realize the management of network resources is a common practice in broadband networks at present. OSPF (Open Shortest Path First) is an Interior Gateway Protocol (Interior Gatew...
