Abstract

The invention discloses an adaptive adjustment method and system for a service bandwidth, and an SDN controller, relating to the field of transport network. The method comprises the steps of monitoring and sampling Ethernet service traffic and packet loss rate periodically according to an adaptive bandwidth adjustment parameter configured by a client; calculating an actual service traffic according to the packet loss rate and a service traffic sampling value; and determining whether to perform service bandwidth adjustment according to the actual service traffic, if yes, sending a bandwidth adjustment instruction to a network element device, and reporting an received adjustment result returned from the network element device to the client. The bandwidth of a private line service of the Ethernet is adjusted dynamically and adaptively in real time according to change of the actual service traffic, so that the actual service traffic of the private line service of the Ethernet is matched with the service configured bandwidth, and the use ratio of the transmission bandwidth resources is improved.

Description

technical field [0001] The invention relates to the field of transport networks, in particular to a service bandwidth self-adaptive adjustment method, system and SDN controller. Background technique [0002] At present, the bandwidth of the Ethernet private line service provided by the operator in the transmission network is fixedly configured according to the maximum bandwidth demand of the customer. When a customer's service bandwidth requirement changes, it is necessary to go through processes such as application, approval, construction, and commissioning to complete the adjustment of the leased line service bandwidth. The current Ethernet private line service provision mode cannot dynamically adjust the bandwidth in real time according to the change of the customer's actual service traffic, and the service bandwidth adjustment takes a long time. As a result, the actual utilization rate of the leased line bandwidth is often very low, thereby increasing the customer's usa...
