Embodiment Construction

[0097] The attached drawings are only for illustrative purposes, and cannot be understood as a limitation of the patent;

[0098] In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0099] For those skilled in the art, it is understandable that some well-known structures in the drawings and their descriptions may be omitted.

[0100] The technical scheme of the present invention will be further described below in conjunction with the drawings and embodiments.

[0101] Such as Figure 1-2 As shown, the present invention proposes a cross-domain collaborative resource allocation method for an optical fiber wireless converged network. The optical fiber wireless converged network includes an EPON network and a wireless optical network. The EPON network includes an optical line terminal OLT and an optical splitter, and the optical line terminal OLT upstream Connected to the bac...

Abstract

The invention discloses a cross-domain cooperative resource allocation method for an optical fiber wireless convergence network. The method comprises the following steps of: dividing the network intoa plurality of branch network regions according to a proximity principle and a whole network approximate average principle; through a load-transferred ONU and wireless node cooperative region resourceredistribution mechanism, redistributing routes for influenced service requests of a dormant region according to service priorities, and selecting a maximum weight path as a current forwarding path of the service request and a source node MAP thereof based on constraint factors; an energy consumption model of a whole network is established through calculation of on-off energy consumption EONU ofONU equipment of an optical network unit, on-off energy consumption EMAP of MAP equipment of a wireless node and forwarding energy consumption Etrans of a service request, and then network service maximization earnings are obtained in combination with a network service earning model. According to the technical scheme provided by the invention, the ONU subjected to load transfer and the wireless node cooperatively sleep, and the route is redistributed according to the priority; and the service quality of the high-priority service is ensured on the basis of maximally reducing the network energyconsumption.

Description

Technical field [0001] The invention relates to the field of resource allocation of optical fiber wireless converged networks, in particular to a method for cross-domain collaborative resource allocation of optical fiber wireless converged networks. Background technique [0002] The power distribution communication network is an important connection between the backbone transmission network in the power communication network and the user's local network, and it carries services such as power dispatch, smart meter reading, and distribution network protection. As the scale of the power grid continues to expand, the number and types of services carried on the power distribution communication network are increasing, making the traditional single networking structure unable to meet the end-to-end and differentiated transmission quality requirements of heterogeneous services. Optical fiber wireless broadband access network not only has the advantages of high bandwidth and low loss of o...
