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.
