Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the traditional optical access network is relatively closed and does not have the ability to open control to users, which limits new service innovation and user experience improvement, and solves the instantaneous burst of southbound control traffic caused by bandwidth customization , increasing control delay and affecting network stability

Embodiment Construction

[0063] With the rise of OTT applications, wired broadband access networks have gradually changed from bandwidth-driven to application-driven. Only the business or users themselves can truly understand their own QoS requirements and usage tendencies. Therefore, network capability openness and programmability have far-reaching implications for future development. Meaning, because the access network resources are insufficient and in a state of competition, the fine control and intelligence of the access pipeline can ensure the priority service of key services and maximize the user network experience under the condition of limited bandwidth resources.

[0064] Software Defined Network (SDN, Software Defined Network) is a basic network architecture based on open interfaces to realize software programmable. Compared with traditional networks, software defined networks have the following advantages: separation of control and forwarding, logical centralized control, open control interfa...

Abstract

The present invention discloses a software defined optical access network-based method and system for time-based bandwidth customization. The system comprises an application layer, a control plane and a data plane. The application layer receives and analyzes a bandwidth customization request of a user, and sends the bandwidth customization request through a northbound interface. The control plane receives and analyzes the bandwidth customization request, reserves network bandwidth resources according to a fact that a network bandwidth margin meets the bandwidth customization request, updates a bandwidth calendar, writes a to-be-delivered flow table into a node flow table and updates the node flow table, determines a flow table delivery time and starts a timer, reads the updated flow table when the time arrives, and sends an open flow message through a southbound interface. The data plane receives and analyzes the open flow message, sends the open flow message to a data abstraction layer according to the effective time of the open flow message, and completes configuration from the flow table to a forwarding device. Through adoption of the software defined optical access network-based method and system for time-based bandwidth customization, the access bandwidth is open to the user and is customized according to needs, actual network demands are met so as to improve the use experience, a network operator can develop a value added service, and the network flow can be smoothed by referring to a reasonable pricing policy.

Description

technical field [0001] The invention relates to the technical field of wired broadband access networks, in particular to a method and a system for realizing timely customization of bandwidth based on a software-defined optical access network. Background technique [0002] The explosive growth of Internet data traffic has accelerated the broadbandization process of the access network. The optical access network has the advantage of high bandwidth and low cost, and has been rapidly developed and deployed in large numbers in recent years. However, in recent years, the rapid rise of the IT industry and the rapid development of OTT services have been widely recognized by users, which has caused a huge impact on the communication industry: on the one hand, OTT services occupy a large amount of bandwidth and directly provide services and billing to customers, making the basic network become simple On the other hand, the openness of IT requires irreconcilable conflicts with the clos...
