Embodiment Construction

[0057] As shown in the figure, the implementation steps of the present invention are as follows:

[0058] Step 1: Initialize the network topology, set the capacity of each link as its link weight; set the high threshold and low threshold of ONU sleep, as well as the ONU status report cycle and the optimization cycle of the radio frequency interface.

[0059] Step 2: Whenever a business arrives in the network, calculate the sum of the weights from the node to the OLT that meets the maximum hop limit for service forwarding and add the shortest path after adding the hop compensation factor. If the path exists, it is used as the forwarding path of the service, and the service is forwarded according to the path. Otherwise, if there are dormant radio interfaces in the network, enable all dormant radio interfaces to recalculate routes and perform forwarding.

[0060] Step 3: The transmission of services will occupy the link capacity, modify the weight of the link, and its value is t...

Abstract

The invention provides a hybrid access network energy saving method based on optical network unit (ONU) and radio frequency interface hibernation and belongs to the technical field of communication networks. The method comprises the following steps that firstly, every time a service is generated, a routing method with the sum of weights and hop count compensation is used for calculating a route for the service, wherein if the route does not exist, all hibernation interfaces are woken up, calculation is conducted again, and then the service is forwarded according to a calculation result; meanwhile, when report time of ONUs is up, each ONU sends a report package to an optical line terminal (OLT), and the OLT makes decisions and controls working modes of the ONUs according to content of ONU reports after receiving the report packages; when optimization time of the radio frequency interfaces is up, priorities are allocated for the interfaces, interface services are transferred according to the sequence of the priorities, the interfaces with the service being zero are made to hibernate, and the purpose of saving energy is achieved. By the adoption of the fiber-wireless hybrid access network energy saving method based on ONU and radio frequency interface hibernation, network energy consumption can be reduced, and energy efficiency of network equipment can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to an energy-saving method for an optical fiber-wireless hybrid access network based on dormancy of an ONU and a wireless radio frequency interface. Background technique [0002] In recent years, due to the emergence of interactive games, long-distance video conferencing and other multimedia application services, the user's demand for network bandwidth is constantly increasing. The bandwidth and reliability of the backbone network have been greatly improved due to the progress and development of optical network technology. At the same time, several traditional access methods (such as digital subscriber line DSL, coaxial cable, etc.) have been increasingly unable to meet the growing needs of users due to limitations in bandwidth and flexibility. Therefore, in the access network, the problem of how to provide users with flexible broadband access needs to be...
