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...

The invention discloses a method and system for realizing bandwidth customization on time based on a software-defined optical access network. The system includes: an application layer receives and parses a user's bandwidth customization request, and sends a bandwidth customization request through a northbound interface; a control plane receives and parses the bandwidth Customize the request, reserve network bandwidth resources according to the network bandwidth margin to meet the bandwidth customization request, update the bandwidth calendar, write the flow table that needs to be delivered into the node flow table and update it, determine the delivery time of the flow table and start the timer, and arrive at Read the updated flow table after a while, and send openflow messages through the southbound interface; the data plane receives and parses the openflow messages, and sends them to the data abstraction layer according to their effective time, and completes the configuration of the flow table to the forwarding device. The invention realizes that access bandwidth is opened to users and can be customized on demand, meets actual network requirements to improve user experience, enables network operators to carry out value-added services, and can smooth network traffic with a reasonable pricing strategy.
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...
