Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] One aspect of the present invention provides a method for dynamically adjusting the bandwidth of a software-defined optical access convergence network, the method comprising:

[0038] Multiple paths of the same source and same destination are formed into a path group, and the maximum number of paths in the path group, the minimum number of paths in the path group, the maximum bandwidth of each path, and the minimum bandwidth of each path are set;

[0039] When the monitored traffic value exceeds a certain upper threshold, increase the number of paths in the path group, adjust the bandwidth of each path, and redirect some traffic to paths with less load;

[0040] Wh...

Abstract

The invention provides a dynamic software definition light access to aggregation network bandwidth adjustment method and a device. Multiple homologous homoclinic paths form a path set, and corresponding flows are distributed to the multiple paths. Through aggregation network flow monitoring, the flow distribution path quantity and the flow on each path are dynamically adjusted, not only can a request success rate and a user bandwidth satisfaction degree be improved, user experience is improved, but also a purpose of load balancing can be realized through dynamically adjusting the flow paths, and a resource utilization rate is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more specifically, to a method and device for adjusting the bandwidth of a software-defined optical access convergence network. Background technique [0002] As the main force of wired broadband, optical access technology has also been developed rapidly. High speed, large capacity, long distance, multiplexing, and low cost have always been the goals pursued by academia and industry. However, the development of optical access network faces many problems. The optical access network is close to users and faces diverse and personalized application requirements, while the traditional optical access network supports a single type of service and only has limited QoS guarantee capabilities, making most broadband access services converge (such as monthly subscription Best-effort service) has gradually become a dumb pipeline. On the one hand, the differentiated needs of users cannot b...
